The new K11 Ancients Common and Rarer Alleles tests are being run by Dilawer Khan, creator of the Gedrosia stable of admixture calculators available on GEDMatch.com, and of the EurasianDNA.com website.  This new test uses a new set of principles, based on using ADMIXTURE to produce more reliable ancient results.  I commissioned him to run my own 23andMe file through the tests, to produce the following results and PCA's/

PCA for Common Alleles (my position "Norfolk"):

PCA for Rarer Alleles (my position "Norfolk"):

The K11 Ancients common Alleles results should reflect the older ancestry most accurately.  In summary, that gave me:

  1. 48.6% Neolithic Farmer
  2. 26.5% Copper Age Steppe Pastoralist
  3. 24.9% Western Hunter-Gatherer

Thank you Dilawer.

How have other tests seen similar admixture?

I previously commissioned David Wesolowski (Eurogenes stable on GEDMatch and of Eurogenes Blog) to run my raw file through his K7 Basal-rich test.  He produced the following results:

  1. 57.1% Villabruna-related
  2. 28.8% Basal-rich
  3. 14% Ancient North Eurasian.

These are two very different tests, of admixture between different sets of population, of different time periods.  What I do find interesting is the 14% percentage of ANE (Ancient north Eurasian) relates quite favourably to what I understand it's admixture percentage is to Yamna or Steppe pastoralist.  Dilawer gives me 26.5% Steppe.   I have previously heard that the Yamna were circa 50% ANE, and the remainder of mixture of other Western Eurasian Hunter-Gatherer groups, including Caucasus Hunter-Gatherers.

The K11 Ancients test does suggest that I have a surprisingly high amount of ancestry from the Neolithic Farmers, that were in Europe previous to the arrival of the Steppe migrants around 4,900 years ago.  This is actually consistent with my other Ancient admixture test results.  The K7 Basal-rich test for example, had given me 28.8% Basal.  The Basal Eurasians are a hypo-theoretical "ghost" population that was among the founding admixture of the Neolithic Farmers, in a similar way that the ANE were among the founding admixture of the Steppe Pastoralists.  Again then, the two tests do tally reasonably well in determining where my personal percentages of ancient DNA  originate.

Why do I have so high percentages of Neolithic Farmer and Basal Eurasian I do not know.  My DNA flavour is a slight extreme, and atypical even for an English person, and more so for a Briton.  My recorded genealogy is all SE English, mainly East Anglian.  I would love to see the results of other East Anglians, as I suspect to them, that I am not such an extreme.  However, even if this was the case, it doesn't explain why modern East Anglians would have lower Steppe, and more Neolithic than either West British, Scandinavians, or even ancient DNA from Anglo-Saxons.  Higher percentages of Neolithic ancestry today are usually found to the South, peaking in Sardinia, then Iberia.  A favoured explanation is that the SE English could have had a lot of input from the South, via the French during Norman and Medieval periods.  I'm not totally convinced - yet.

A third new ancient admixture test that I might use here in the MDLP Project Modern K11.  On GEDMatch Oracle, it proposes a number of genetic distances to ancient DNA samples:

1 British_Celtic @ 6.948432
2 Bell_Beaker_Germany @ 8.143357
3 Alberstedt_LN @ 8.426399
4 British_IronAge @ 9.027687
5 Halberstadt_LBA @ 10.273615
6 Bell_Beaker_Czech @ 12.190828
7 Hungary_BA @ 12.297826
8 Nordic_MN_B @ 12.959966
9 British_AngloSaxon @ 12.993559
10 Nordic_BA @ 13.170285

Using 4 populations approximation:
1 Bell_Beaker_Germany + Bell_Beaker_Germany + Corded_Ware_Germany + Hungary_CA @ 1.085814
2 BenzigerodeHeimburg_LN + BenzigerodeHeimburg_LN + Corded_Ware_Estonia + Hungary_CA @ 1.089547
3 Alberstedt_LN + Bell_Beaker_Germany + Corded_Ware_Germany + Hungary_CA @ 1.117882
4 Bell_Beaker_Germany + BenzigerodeHeimburg_LN + Hungary_CA + Srubnaya_LBA @ 1.149613
5 Bell_Beaker_Germany + British_IronAge + Hungary_CA + Karsdorf_LN @ 1.185312
6 Alberstedt_LN + BenzigerodeHeimburg_LN + Hungary_CA + Sintashta_MBA @ 1.226794
7 Nordic_BattleAxe + Hungary_BA + Hungary_CA + Karsdorf_LN @ 1.234930
8 Nordic_BattleAxe + BenzigerodeHeimburg_LN + Hungary_CA + Unetice_EBA @ 1.238376
9 Alberstedt_LN + Hungary_BA + Hungary_CA + Yamnaya_Samara_EBA @ 1.247371
10 Bell_Beaker_Germany + Hungary_CA + Nordic_LN + Srubnaya_LBA @ 1.268124

If I look at four population distances, then based on the samples available in the test, I'm looking pretty European Bell Beaker, with Corded Ware and Yamna appearing. My closest single population in the samples is a surprising British Celtic!  More samples from the European Neolithic might turn those results around.

The Beaker phenomenon and genetic transformation of Northwest Europe 2017. A layman's take.

They say that you cannot write prehistory, but here in Britain, prehistory is currently being rewritten, and it's thanks to DNA.  A new study , "The Beaker Phenomenon, And The Genomic Transformation Of Northwest Europe" has been published on BioRxyv.  A new study that recently analysed the DNA of 170 ancient human remains in Europe.

A little background...

1. British Archaeology and the Bell Beaker

British archaeologists have long been aware of a late prehistoric artifact culture found across the British Isles, and across large areas of Western Europe.  It bridged the Late Neolithic and Early Bronze Age periods around 4,400 to 3,800 years ago.  It was characterised by the use of fine bell-shaped beaker pots, usually red ceramic fabric, heavily decorated with simple motifs.  These motifs were characteristically impressed with a fine toothed comb or dentated spatula.  Many Bell beaker burial rituals have been excavated and studied.  The inhumed body would usually be crouched on the side, roughly on a north to south alignment.  A bell beaker would often be stood near to the body, at the feet, or near the head.  Other grave goods often included barbed and tanged flint arrowheads, flint flakes and blades, antler picks, sometimes one or two more beakers, amber beads, copper awls, and gold earrings / hair rings.  64% of British Beaker burials were flat graves, but sometimes a barrow or cist would be erected above it (Beaker Pottery of Great Britain & Ireland. DL Clarke.  CUP 1970).

Above, a flint barbed & tanged arrowhead of the Beaker Culture, that I found and recorded during a surface collection survey some years ago.

Archaeologists studying the artifact culture in Britain, compared the British finds to those on the Continent in order to try to find an origin for these people.  They suggested either Brittany in North West France, or the Lower Rhine Valley, in the Netherlands and Northern Germany.  Some alternatively promoted Iberia as the origin.

Then British Archaeology entered an intellectual phase where it became fashionable to dismiss migration or invasions of people, in favour of cultural exchange.  Pots not People.  Rather like today, we British wear denim, t-shirts, listen to R&B, and drink coke.  However, we have not been displaced by North Americans - we just absorbed the artifacts of another culture.  From the 1970s on, many late prehistoric migrations were dismissed by British archaeologists as cultural exchanges rather than representing population displacement.

2. The New Population Genetics and the Steppe Pastoralists.

A new field of study has been gathering pace with the arrival of the 21st Century, that uses genetic evidence, to explore past migrations, movements, admixtures, and origins of peoples.  The earliest pioneers used blood types, then mitochondrial DNA mutations, followed by STR of Y-DNA.  Some of the early conclusions supported the new orthodoxy of British Archaeology.  Stephen Oppenheimer's infamous publication "The Origins of the British" championed that there had been little change in British populations since the Ice Age.  They were to be proven wrong.  Early conclusions, based on little evidence, misunderstandings that were later corrected with more data, seriously damaged the reputation of population genetics in British prehistoric studies.

The most common Y-DNA haplogroup of Western Europe, particularly of Ireland and Britain was R1b.  Early mistakes gave this male haplogroup an Ice Age origin of the Basque Region in Southwest Europe.  As more data gathered, and debate developed, it became apparent that the origin was not the Basque region, but the Pontic and Caspian Steppes of Eurasia!  It became associated with an archaeological culture in Southern Russia called the Yamna.  The R1b and R1a haplogroups appeared to have spilled off the Steppes into Europe during the Copper Age during a significant migration event around 4,900 - 4,600 years ago.  In Eastern and Central Europe, this migration of pastoralists appears to be responsible for the fused artifact culture known as the Corded Ware (again, after a prehistoric pottery style).

A few lectures on Youtube to watch:

Havard lecture by David Reich 2015.

CARTA lecture by Johannes Krause 2016

That brings us up to date.  In summary, population geneticists have discovered a movement of people, not just pots, from the Steppes into Europe.  Modern Europeans descend from an admixture of three major founder populations: 1) the Western Eurasian hunter-gatherers, then a layer of 2) Early Neolithic farmers (that originated in Anatolia and the Middle East), and finally, 3) the Steppe Pastoralists.  The actual mix varies not only from person to person, but also regionally across Europe.

So how does the Bell Beaker Culture of Britain and Western Europe fit into all of this?  The strong assumption over the past couple of years was that the diffusion of R1b Y-DNA haplogroups occurred then, so therefore, it was a simple extension of this westward drift across Europe that originated on the Pontic and Caspian Steppes.  It first spawned the Corded Ware Culture in Central Europe, but then when it met Western Europe, spawned the Bell Beaker Culture.  However, until now, this hypothesis hadn't been tested.

The Beaker phenomenon and genetic transformation of Northwest Europe 2017

Has now examined some of these questions, through the examination of an unprecedented scale of ancient DNA sampling. The link to their published document (which is still awaiting peer review) is at the top of this post, and I'd invite others to read it for themselves.  An article covering the document can also be read on the Scientific American.  However, I personally with my layman head take five suggestions from the study.

  1. They found that the DNA of human remains on Continental Europe did not suggest one cohesive or homogeneous population.  There was in this case, evidence of cultural diffusion.  Different peoples were taking on the Bell Beaker artifact assemblage in Western Europe.  Pots rather more than people.  This was a great surprise, as we still know from the earlier study, that much of our DNA and Y-DNA in particular, originated around 400 years earlier from the Eurasian Steppes.  However, although the Central European Corded Ware Culture does still appear to have been a response to that great influx of new people from the Steppes, the picture with the Western European Bell Beaker is more complex.
  2. An exception was Britain.  Here, the remains associated with Bell Beaker Culture were all one population, and they were very different to the earlier Neolithic population of Britain.  It appears to have been a case of population displacement.  They suggest at least 90% displacement!  It means that very few or none of our Neolithic ancestors built the amazing monuments of Neolithic Britain.  They were built by earlier peoples, that our ancestors displaced.
  3. They confirm a Lower Rhine origin as most likely for the British Beaker People.  The ancient DNA that most closely matched British Beaker DNA, came from Beaker human remains in the Netherlands and Northern Germany.  This correlates nicely with the 1970 archaeological study mentioned above.
  4. It's confirmed.  Previous to their entry into the British Isles, there is no evidence of any Steppe ancestry, no Steppe autosomal DNA, no Steppe Y haplogroups such as R1b-L21 here.  (Nor any mtDNA haplogroup H6a1).  The Beaker people from the Lower Rhine, brought the initial layers of this DNA to Britain.  The founder population were admixed, but with significant percentages of Steppe ancestry, particularly on Y lines.
  5. The previous Neolithic Farmer population were mainly Y haplogroup I2, and appear to have descended mainly from populations in the South, from Iberia, rather than from the Danube, although before that from Anatolia.  The modern population that is closest to them today are Sardinians.

Also as a layman, I guess that this suggests that most, or even any "Neolithic Farmer" DNA suggested by our ancient ancestry calculators, was most likely picked up elsewhere than Britain, and brought here by later migrants (descended through that mixture of cultural diffusion and admixture), rather than directly from the British Neolithic population.

I also notice a correlation with an Irish study last year ("Neolithic and Bronze Age migration to Ireland and establishment of the insular Atlantic genome" Cassidy etal.  Queens University Belfast 2016), that again, suggested major displacement of earlier peoples in Ireland, at the end of the Neolithic, by a population with largely Steppes origins.

An English Ancestry - Documentary and DNA

Foreword

A little foreword. The following is not some sort of ridiculous claim to being "100% British", pure, or any other sort of nonsense.  The English are after all, a very admixed population.  It is just what I have found.  If at any time I should happen upon ancestors from anywhere from Afghanistan, to Zimbabwe, I'd be equally proud of them.

This blog post enables interested parties to compare the documentary genealogy of an East Anglian, to the DNA for ancestry tests.  Warning - it could make you lose some trust in some DNA for ancestry test results!

The Paper Trail and Family History

I was born in Norfolk, to a local family.  My current gedcom database includes records of 1,882 family members and ancestors for my children.  I currently have records of 274 of my direct ancestors.  All were in South-East England, predominantly in Norfolk, and appear to have been English.  Most of my recorded ancestors over the past 330 years, appear to have been rural working class.  They most likely descended predominantly from the medieval English peasantry.

Here is a recent pedigree fan chart demonstrating recorded coverage of my direct ancestry over the past 11 generations:

That is my documented family history and ancestry.  I would dare postulate that most of my ancestors previous to this record, most likely descend from the peasants and freemen of medieval East Anglia, and also in the Thames Valley of Oxfordshire, and Berkshire.  What else can I add?  

The Genetics

So how does the above documented genealogy compare with the genetic genealogy?  Let's see.

First of all, the auDNA (Autosomal DNA tests for ancestry), generally agree that I'm 100% European, and at least mainly North-west European.  I can't argue with that.  At that level auDNA tests work reasonably.  Let's look at my personal auDNA tests for ancestry, see what they report:

Living DNA Standard mode

This new DNA test, with a very rich and good quality data set for the British Isles, has so far proven to be by far the most accurate that I have so far commissioned.  I recommend it particularly for testers with significant British ancestry, as it tries to break British ancestry down into 21 regions.

100% European
Regional:
74% Great Britain & Ireland
10% Europe (South)
7% Europe (North and West)
10% Europe (unassigned).

Sub-regional:

39% East Anglia
8% South Central England
5% South East England
5% Lincolnshire

2.5% Cornwall
2.4% North Yorkshire
2% South England
1.9% Devon
1.6% Central England
1.5% North West England
1.3% South Yorkshire
1.2% Northumbria

3.5% unassigned Great Britain & Ireland

10% Tuscany (Europe South)
5% Scandinavia (Europe North and West)
2% Germanic (Europe North and West)
9.7% Europe unassigned.

The Living DNA Test was surprisingly good at detecting many of my ancestors at sub-regional level, into the English regions.  Not perfect by any means - but with an impressive accuracy compared with any other auDNA tests for ancestry that I have investigated.  The Scandinavian, Germanic, and some of the unassigned percentages I am confident, were really East Anglian.  The Tuscan percentage, I cannot explain - but I will be watching out for other SE English test results, to see if it is a background pattern.

23andMe V4 chip, Ancestry Composition speculative mode (before any phasing):

100% European:  94% NW European.  3% Southern European.  3% Broadly European.

Broken down to:

32% British & Irish

27% French & German

7% Scandinavian

29% Broadly NW European

2% Broadly Southern European (including 0.5% Iberian)

23andMe V4 chip, Ancestry Composition speculative mode phased with one parent (mother):

100% European:  96% NW European.  1.8% Southern European.  2.2% Broadly European.

37% British & Irish  (23% from father, 14% from mother)

22% French & German  (12% from father, 10% from mother)

1% Scandinavian  (from mother alone)

36% Broadly NW European  (23% from father, 13% from mother)

2% Broadly Southern European (1% from father, 1% from mother)

The 23andMe test for ancestry fails to recognise English - and commonly splits our English ancestry into British & Irish, French & German, Scandinavian, Broadly North west European, and often with a small percentage of Southern European.  However, it is NOT the worse auDNA test for ancestry by any means.

auDNA Tests for Ancestry - a conclusion

The tests prove very good at identifying that I am pretty much 100% European, and usually see me as mainly North-West European.  Ironically, as my Y-DNA below demonstrates, I do have some distant Asian ancestry on that particular line.  The only test that might some how pick this up is the latest FT-DNA My Origins (2:0), but it is probably coincidental.

The tests in general, are not so good at identifying me as English, or even as British.  In the cases of the FT-DNA, Ancestry.com and 23andMe tests, they have not made any attempt to create reference data sets for English populations, in order to distinguish their medieval (and earlier) admixture between older British, and Continental populations.  Instead, they tend to bundle English with Irish, Welsh, and Scottish.  As a result, English testers receive confusing results with lower than expected levels of British / Irish, and percentages of French, German, Scandinavian, and Southern European that they are wrongly assured are the results of recent family admixture from those parts of Europe.  Only Living DNA has made an effort to untangle this issue.

I accept that my results are consistently atypical for a British tester, even perhaps an extreme for an English tester.  They are more Continental than the average.  Sometimes French.  Sometimes Germanic, Sometimes Scandinavian.  I cannot account for this with my documented and recorded family history, which is localised, rural, totally South-East English, and strongly East Anglian.  I receive lower than average (for a British person of British recorded ancestry) British ancestry from all three DNA test businesses.  The only answer that I can see, is that my ancestry is so strongly rural and localised in East Anglia, that I have higher than average admixture from the 5th to 10th Century AD immigration events - the Anglo-Saxon, and perhaps Anglo-Danish, and Anglo-Norman.  It isn't really a surprise - particularly when you look at the above map of my mother's recorded ancestry.

This does though raise the question, how much are these auDNA tests affected by background population admixture?

The second aspect to my results, is that they keep producing a Southern European influence.  On 23andMe, this manifests itself as only a small percentage - but phasing reveals that I inherited it from both parents.  I surveyed 18 English testers on 23andMe, and on speculative mode, no less than 16 received small percentages of Southern European.  Therefore, it would in this case appear to be a case of population background.  However, FT-DNA 1:0 threw a whopping 32% Southern European at me, but then retracted that in the new version.  23andMe hints at Iberian.  DNA.land suggests North Italian and Balkan.  Then Living DNA suggests 9.6% Tuscany!  I cannot account for these sort of percentages within my known recorded genealogy.  I'm currently open minded to having unknown Southern European ancestors within the past ten generations, or to it being some sort of English population background signal, perhaps related to unknown prehistoric admixture, Roman British admixture, Norman Medieval admixture, or a combination.

I want to discuss and look at third party analysis of these results further down in this post, but first, I want to report my DNA Haplogroups, as I feel that they are more precise:


My Haplogroups

My Y-DNA Haplogroup

This is the haplogroup that you inherit on your direct paternal line, from your father, from his father, and back in time.  I have tested my Y-DNA at 23andMe, then FT-DNA Y111, Big Y, and have had further analysis of my raw data at YFull, and FullGenome Corp.  In other words, it has had a lot of investigation!

Y Haplogroup L (M20)

This is regarded as rare in Europe, and generally thought of a minority haplogroup spread across Western, Central, and Southern Asia.  Going further downstream, I currently reach:

Y Haplotype L1b2c (L-SK1414)

This is regarded as a very rare sub clade, of a rare haplogroup!  The FT-DNA Y Haplogroup L Project, currently contains only five SNP confirmed L-SK1414, and thirteen STR predicted L-SK1414.  I know of one other SNP confirmed sample, and a few more STR predicted.  The confirmed (including myself) are from: Southern England (English), Lebanon (Druze), Turkey, USA (German) and Makran, SW Pakistan (Baluchi).  The STR predicted are from Southern England, France, Russia, Kuwait, UAE, Eastern Iran, and Saudi Arabia.

I currently regard the origin of Y hg L1b2c as most likely to be in the region of Iran and Iraq.  I believe that I most likely had a single Y ancestor, that travelled from Asia to Southern England sometime between 2,000 years ago, and 500 years ago.  A "medieval" Asian traveller".  No autosomal DNA tests have so far yielded any evidence of any Asian ancestry above that expected for an English person.  Therefore, any auDNA evidence has likely been washed out by genetic recombination.

My earliest documented surname ancestor on record is my 6xgreat grandfather, John Brooker of Long Wittenham, Berkshire, born circa 1725.  Some of the STR predicted L-SK1414 descend from a Thomas Chandler, that lived about the same time (early-mid C18 AD) at Basingstoke, which is only 32 miles from Long Wittenham.  Most likely, John Brooker and Thomas Chandler shared a common Y ancestor.

Red are L-SK1414. 

FT-DNA currently see my known haplotype as L-FGC51036 (downstream of SK1414).  YFull currently list my haplotype as L-FGC51074 (SK1414).

My mt-DNA Haplogroup

This is the mitochondrial DNA haplogroup that you inherit on your direct maternal line, from your mother, from her mother, and back in time.  I have tested my mtDNA at 23andMe, then FT-DNA mtFull Sequence. My 23andMe raw data was also correctly predicted by the James Lick mthap analyser website and by WeGene.  In other words, it has also had a lot of correlation and investigation!

MT Haplogroup H (Helen)

This is the most common mtDNA haplogroup in Europe, but it is also common in Asia, where it is believed to have originated.  Possibly originating in Arabia, before moving up to Central Asia.  Further downstream?

MT Haplogroup Branch H6a1a8

H6a1, based on studies of ancient DNA to date, most likely originated on the Pontic and Caspian Steppes of Asia. It has been found in the ancient DNA of human remains, from the Copper Age Steppe pastoralist Yamnaya Culture.  H6a1 and H6a1a have both been found in the ancient DNA of human remains, from the Early Bronze Age East European Corded Ware Culture.  No H6a1 or descendant branches have yet been recovered from earlier contexts in Europe.

Therefore it would appear that my mtDNA was carried into Europe from the Eurasian Steppes during the Early Bronze Age, as a part of the great Yamna expansion of that time.  Most haplogroups associated with this expansion have been male Y haplogroups, which makes H6a1 of particular interest, because it was carried into Europe by Steppe women.

I haven't found enough current data on branch H6a1a8 to determine when or how it entered Lowland Britain, but it most likely formed during the Bronze or Iron Age, and so far, I've mainly seen North American and Austrasian H6a1a8 testers that feel that they most likely have British or Irish maternal ancestry.

I trace my direct maternal (mtDNA) line to my 6xgreat grandmother, Sarah Hardyman (nee Briting), who lived nearby at Bunwell, Norfolk, and was born circa 1725.

Upper Palaeolithic and Mesolithic Hunter-Gatherer ancestry

My Y line as we have seen, was most likely in the area of modern day Iran or Iraq, perhaps in the Euphrates and Tigris valleys, or perhaps in the Zagros Mountains, hunting animals such as the Ibex.  My mt-DNA line was most likely in a hunter-gatherer band somewhere in Asia.  Perhaps Central Asia.  What about my other Ice Age ancestors?

David Wesolowski's K7 Basal-rich test

Villabruna-related

The Villabruna cluster represents the DNA found in 13 individuals in Europe from after 14,000 years ago.  They were Late Ice Age hunter-gatherers.  They appear to have links with the Near East.  The current thought is that they replaced earlier groups of hunter-gatherers in Europe.  The DNA of people in the Middle East and Europe pulled together at this time, and they may represent an expansion from the South-East.  Much of the Aegean Sea would have been dry, with low sea levels (glaciation), so the migration may have been easy.  It is believed that they had dark skin, and blue eyes.  They were possibly, the last hunter-gatherers of Europe and the Middle East.  They may have contributed to our DNA both through or either, later Asian or European admixtures.

David gives the English average as 56.7%.  My result is 57.1%

Basal-rich

The Basal Eurasians are a hypothetical "ghost" population derived from DNA studies.  It is suggested that they splintered from other modern humans 45,000 years ago, presumably outside of Africa, somewhere around the Middle East.  They significantly contributed DNA to the Early Neolithic Farmers of the Fertile Crescent and Anatolia, and consequently, on to all of us modern West Eurasians.  

 David gives the English average as 26.5%.  My result is 28.8%

Ancient North Eurasian

Another Ice Age hunter-gatherer "Ghost" population, but this one has been associated with human remains and an Upper Palaeolithic culture (Mal'ta-Buret') at Lake Baikal, Siberia.  We know that it significantly contributes to modern West Eurasians, through earlier admixture on the Eurasian Steppes.  Copper Age pastoralists then carried it westwards into Europe with their later expansion.

David gives the English average as 16.6%.  My result is 14.0%

Neolithic and Bronze Age mix ancestry

My Y line at this time as we have seen, may well been Early Neolithic Farmers in the Fertile Crescent of Mesopotamia.  My mtDNA line would have most likely have been women of the Yamnaya culture on the Eurasian Steppes, in Copper Age pastoralist tribes.

Global 10 Test

The recent Global 10 test, run by my friend Helgenes50 of the Anthrogenica board, resulted in:

  • 55% Baalberge_MN (European Middle Neolithic)
  • 38% Yamna_Samara (Eurasian Steppe Pastoralist)
  • 7% Loschbour:Loschbour (Late Eurasian hunter-gatherer)

That is 55% European Neolithic Farmer, 38% Yamnaya Steppe Pastoralist, and 7% European hunter-gatherer.

Breaking through - my Brooker Line

My 2xgreat grandmother Emily Smith (nee Barber), with her son Sid Smith in Norwich.  Emily was born 1859 at Hedenham, Norfolk.

What did my 3 x great grandfathers do for a living?

3 x great grandfather 1.  John Brooker.  Shepherd, and an agricultural labourer.  Born 1820 at Rotherfield Peppard, Oxfordshire, lived later in life in the surrounding villages of Harpsden and Shiplake. Married Mary Ann in 1845, they had ten children.  He died in 1912.

3 x great grandfather 2.  Henry Shawers.  Harrow Weaver.  Born about 1826, the son of a copper smith, I have still not found their origins. He lived in the East End of London.   He married Elizabeth at Bethnal Green, London in 1857, and they had at least two children, while they were living at Haggerston, London.

3 x great grandfather 3.  William _____.  Miller.  Born 1815 at the village of Saham Toney in Norfolk.  He was named as the father of my illegitimate born great great grandfather.  At the time, William was a journeyman miller, and he had been married to another woman less than a year.

3 x great grandfather 4.  William _____.  Shoemaker.  Born 1820 at East Dereham, Norfolk.  He was named as the father of my illegitimate born great great grandmother.  She recorded him as her father on her marriage registry entry.

3 x great grandfather 5.  Robert Smith.  Umbrella maker.  Born 1807 at Attleborough, Norfolk.  He lived as far as I can tell, all of his life in Attleborough.  He married Lydia there in 1827.  They had six children, until her death in 1844.  Robert then married Frances.

3 x great grandfather 6.  David Peach.  Shepherd and a drover.  Born 1807 at Maxey, Cambridgeshire.  Maybe as a drover, he met my 3xgreat grandmother, Sarah, from Norfolk.  He took her back to the Etton area.  They married at Holywell, Lincolnshire, in 1835.  They had one daughter, my ancestor.  However, shortly after, David was convicted at Lincoln Assizes of stealing two steers.  He was transported as a convict for life to Van Diemens Land (Tasmania).

3 x great grandfather 7.  Robert Barber.  Agricultural labourer.  Lived at St Michael, South Elmham, Suffolk.

3 x great grandfather 8.  James Ellis.  Agricultural labourer.  Born (1812) and lived at Hempnall, Norfolk.  Married Esther.  They had nine children.

3 x great grandfather 9.  William Curtis.  Agricultural labourer.  Born at Strumpshaw, Norfolk  in 1830.  Married Georgianna in 1852 at Hassingham.  They had nine children.  William died in 1926.

3 x great grandfather 10.  Robert Rose.  Agricultural labourer.  Born 1829 at Lingwood, Norfolk.  He married Sarah Ann at Limpenhoe in 1853.  They had eight children.  Robert died in 1908.

3 x great grandfather 11.  William Key.  Agricultural labourer.  Born 1804 surprisingly, in the City of Norwich, Norfolk.  I suspect that the family were not there for long.  He married Mary in 1823 at Freethorpe, Norfolk.  They had five children.  William died in 1869.

3 x great grandfather 12.  Richard Goffen.  Inn Keeper and Master Carpenter.  Born 1795 at Reedham, Norfolk, where he appears to have lived out his life.  Down by the river, he may have been one of the carpenters working on the wherry vessels.  When he married my ancestor Elizabeth at Reedham, Norfolk in 1843, he was already a widower and 26 years her senior!  However, Elizabeth gave him seven children.  Richard died a happy man in 1866.

3 x great grandfather 13.  James Tovell.  Agricultural labourer and farm bailiff.  Born 1815 at Geldeston, Norfolk.  He married Mary at Chedgrave, Norfolk in 1841.  They lived around the Loddon, Norfolk area for a while, before crossing the river Yare, and settling at Halvergate, Norfolk, by the marshes.  Mary gave him seven children, including two before marriage.  James died at Halvergate in 1900.

3 x great grandfather 14.  William Lawn.  Agricultural labourer.  Born 1804 at Halvergate, Norfolk.  He married Elizabeth in 1831 at Great Yarmouth, Norfolk.  She gave him five children.  William passed away in 1885.

3 x great grandfather 15.  The missing one.  My only unrecorded 3 x great grandparent.  The unrecorded biological father of my illegitimate born ancestor at Rackheath, Norfolk.  The mother was Sarah Thacker, who was born at Salhouse, Norfolk, in 1823.

3 x great grandfather 16.  Reuben Daynes.  Agricultural labourer.  Born 1822 at Brandon Parva, Norfolk.  He moved to Besthorpe, Norfolk, and married Sarah in 1848.  She gave him six children.  Reuben died in 1908.

The Southern European DNA enigma. Option 3. Autosomal DNA Analysis does not work

Here I'm considering the third option to my enigma.  My known ancestry is 100% English.  However, autosomal DNA tests for Ancestry, by commercial companies, and by third party analysis, suggest that I have a mixture of European ancestries, including varying percentages of Southern European.  I'm trying to best explain this phenomena.  In previous posts, I considered 1) that my paper record is incomplete, or biologically incorrect.  2) that something ancient is picked up in analysis of present day English testers - that maybe reflect shared algorithms with ancient admixture, perhaps prehistoric, or Roman.

Now in this post, I consider the third option.  That commercial DNA companies exaggerate their claims to be able to differentiate to any successful degree, between different regions of Europe in my ancestry.  If this is indeed the case, it has significant repercussions for testers for example, in the USA, Canada, Australia, etc.  If they have a poor paper trail, and poorly known ancestry, maybe it's all too easy for them to regard such DNA tests for ancestry, as indisputable and accurate truths.

Commercial DNA companies for Ancestry, are under pressure to supply to market demands.  Their markets have been dominated particularly by USA customers.  Some of them seasoned genealogists with good quality paper trails.  Others, attracted by the easy option to know their ancestry before the, as 23andMe puts it, the Age of Migration before the past few centuries.  Instead of spending a lifetime chasing documents, they can simply send a DNA sample to a company, and know their roots.  People trust the science of DNA testing for ancestry.  That is the demand that commercial companies can cater for.

But what if their abilities to accurately detect ancestry from Autosomal DNA is exaggerated?

Lack of agreement between analysis.

As one evidence.  Test autosomal DNA with three different companies, and you will receive three different results.  That is well known in genetic genealogy circles.  Some apologists excuse it away by pointing to the different companies claims, to be focusing on different periods.  23andMe say that they zoom in on 500 years ago, by rejecting short chains.  Is it really, really possible yet, to be able to zoom in on one particular period?  I'm not convinced.  Is it even possible to securely locate all ancestry from the past 500 years?  I'd expect genetic recombination to wash away an awful lot of ancestral DNA long before that.  The truth is that beyond our great great grandparent's generation, there is less and less chance of us carrying any surviving DNA from any one particular ancestor! Especially from the autosomal DNA passed down on your father's side.  You might have a Balkan g.g.g.g grandfather, but chances are, there will be no evidence of their existence remaining in your autosomes.  His DNA, and all that belonged to his Balkan ancestry, will be lucky to survive the following 250 years, never mind 500 years.  My Y-DNA has strong evidence that I had an Asian ancestor on my paternal line, arrive in Southern England between 1,800 and 500 years ago.  However, nothing remains in my autosomal DNA analysis that suggests Asia.  Washed away.

Getting back to those three companies giving three different ancestries. My South European percentages have varied from 2% (with a hint at Iberia), to 19% (with a hint at Balkans), to FT-DNA's claim of 32%!  Eurogenes K13 hints at Iberia in it's admixture programs on GEDmatch.

Population References

One more thing.  Autosomal DNA tests for ancestry do not use ancient DNA references.  Not yet anyway.  They instead use present-day references, often from their own customer client bases, based on what ancestry they claim.  This is not necessarily the DNA that existed in past populations.  Populations and genes shuffle, genetic drift forms.  I recently read a report that FT-DNA Y data for NW Europe heavily biases to Irish ancestry.  Therefore, references from Americans of Irish and / or British descent, will bias to the West.  The quality of a reference is critical.

Is it all Bunk?

Am I saying that autosomal DNA testing for Ancestry is all a waste of time?  Actually no, not yet.  The tests DO find me to be pretty much 100% European.  That is a success.  Some tests even find me with a degree of confidence, to be NW European.  That is awesome.  However, beyond such regional level, should we be trusting such tests to be providing concrete results, infallible "truths" with a high degree of accuracy?  Shouldn't we be cautious, and regard such speculations as just that - speculations, to be assessed by other forms of evidence?  Some of my ancestors might have lived in Southern Europe.  Maybe Option 1 was correct - one of my Norfolk ancestors brought a Portuguese wife home from the Peninsular Wars.  Perhaps.  Maybe Option 2 was correct - the patterns that DNA companies pick up as Southern European, are ancient, related to Neolithic, Iron Age, or Roman admixture from the South, or sharing ancient ancestry with Southern Europeans.  Maybe.

I'm not at all disenchanted with DNA testing for ancestry though.  I've commissioned five so far this year, including three autosomal DNA tests.  This leads me to my most recent commission.  Perhaps this one will convince me more.  It's a very new test.  I'll post on that next.



Revisiting Southern European for Ancestry

This photo of A Capela dos Ossos (the bone chapel) in Évora, Portugal.  Taken by myself.

First, a recap

I'm English by ethnicity, birth, upbringing, known family history, and by record.  That record, I've researched on and off for more than 25 years, primarily in record offices, but in more recent years also online.  On my personal database I presently have 207 direct ancestors recorded.  All lived in Southern England, with the majority in East Anglia.  All appear to have English surnames.  All recorded religious denominations, English.  The majority were rural working class.  I have a typical English ethnicity and phenotype.  My recorded genealogy stretches back at the furthest to the 1680's.

I'd expect some admixture in there.  I know from my Y-DNA that I have Asian admixture from between 500 and 1,800 years ago on my paternal lineage.  Surely some Hugeonauts, Strangers, Romany, or others at some point.  However, a rare and single event on one line of ancestry doesn't hang around very long in autosomal DNA.  It can be washed out very quickly by genetic recombination - as my Asian, as detected by my Y-DNA, has been.  You should only really see significant traces of admixture, when it is either recent (within the past few hundred years at most), or entered on multiple lines of ancestry.

Therefore, I'd have expected a commercial Autosomal DNA test for ancestry to come fairly close to 100% for British, or even English.  But instead, so far, I've received:

Eurogenes K13 does often suggest Iberian references for admixtures on my results further down the proposal list.  Still, thumbs up for Eurogenes K13!  It gets me as Southeast English correctly!

So... 23andMe claims that I have 2% Southern European and that it comes from both parents, although before phasing, it hinted at Iberian.  FT-DNA claims that I have a whopping 32% Southern European!  DNA.land claims that I'm 19% South European, but Balkan with some Italian, rather than Iberian!  Eurogenes K13 Oracle 4 suggests that if I do have admixture, that it most likely includes Iberian.  My family tree has no evidence of any Southern European people, names, or any Catholicism, etc.  Confusing or what?


Origins of the British, Irish, and English

Above photo taken by myself of the Ring of Brodgar, Orkney

I've modified this from a post that I made on a DNA forum, in response to people discussing out-dated origin stories, in response to a thread looking at ancestral composition for the English.  There is so much misinformation out there, and few people actually try to look at the latest evidences.

It starts by looking at the key points of a recent Irish study.

Cassidy, Martiniano, Murphy etal Study of Neolithic and Bronze Age migration to Ireland

http://www.pnas.org/content/113/2/368.full.pdf

https://www.theguardian.com/science/2015/dec/28/origins-of-the-irish-down-to-mass-migration-ancient-dna-confirms

Key points.

  • Ancient DNA from earlier Neolithic farmers suggests an origin from the Near East.

  • Later DNA from Bronze Age suggests a new population had arrived and dominated, with origins from the Eurasian Steppes, including the present day predominance of Y haplogroup R1b, lactose tolerance, and blue eyes. This displacement event appears to have occurred throughout much of Western Europe. The founder population on the Steppes has been linked to the archaeological population known as the Yamna or Yamnaya.

A background to the Yamna hypothesis to help people understand what the above study supported:

The Yamnaya were a population that existed across the Pontic and Caspian Steppes from what is now Ukraine, to Kazakhistan. They themselves were an admixed population, with ancestry from various different groups of Eurasian hunter-gatherers, and from the ANE (Ancient North Eurasian). They carried a number of successful adaptations, including the use of the wheel, improved selective breeding of horses for both riding and haulage, lactose tolerance, use of horse drawn wheeled carts, and a very successful pastoral based economy revolving around the herding of a number of species of livestock.

They are strongly figured to have carried an Indo-European language into Europe and elsewhere (South and Western Asia). That Indo-European language being the ancestor of the vast majority of modern European languages today. They may have also carried many of the most common haplogroups of modern Europeans, including Y hg R1a, R1b, and some mt hg H types among others.

There is a hypothesis that the earlier peoples of Europe, the Early Neolithic farmers, who had largely descended from early farmers in the Levant / Anatolia, had been suppressed by a number of possible environmental and climatic events. This might have paved the way for such a successful displacement of European populations.

As the descendants of the Yamna swept westwards into Europe during the Copper Age, so they spawned a series of new archaeological cultures including the Corded Ware of Eastern and Central Europe, and the Bell Beaker culture of Western Europe.

The Bell Beaker culture spread from Central Europe to the Western Atlantic Seaboard, and from Portugal up to Scotland. Classic artifacts include archer burials in round barrows, the bell beaker ware pottery, round scrapers, and barbed and tanged arrowheads. It was the dominant culture of Early Bronze Age Europe.

One suggestion is that it spawned the later Iron Age Celtic cultures, including the classic Western Atlantic Seaboard Celtic Culture. This culture may have simply evolved locally and through trade links along that seaboard.

The Irish study above supports the Yamnaya hypothesis. It supports displacement during the Early Bronze Age, and that the present day, fairly homogeneous population of Ireland, largely descends from Copper Age Eurasian Steppe pastoralists.

Okay, so what if we apply that also to the late prehistoric British populations? Scottish and West British today appear to have a close genetic distance to the Irish. How about the lowland SE British? It might be the case, that they had fresh admixture, exchanged with the Continent, and particularly with the expanding Germanic cultures. These events could have occurred even during late prehistory.

Now People of the British Isles (POBI) Study 2015:

http://www.peopleofthebritishisles.org/nl6.pdf

This genetic study looked at the British Isles including Northern Ireland, but excluding the Republic of Ireland. It tested a large sample group of present day British with known local ancestry.

Key points.

  • Orkney had the most distinctive population, with a known high percentage of Norse ancestry.

  • The Welsh were distinct from the English. However, they were the most diverse group, with a clear division between the North Welsh and South Welsh. Cornwall was also distinctive from English.

  • Northern Ireland clusters with Scottish.

  • There was no homogeneous shared British “Celtic” population. The Scottish, North Welsh, South Welsh, and Cornish being quite distinct from each other.

  • The South-East British (most of the English) were surprisingly homogeneous, although the boundaries of the old Anglo-Saxon kingdoms could still be distinguished.

  • The Continental Anglo-Saxon contributiion to present day English people appeared to be circa 10% to 40%. This contradicts Bede's claims of a genocide. The English descend more from earlier British populations than they do from Anglo-Saxon immigrants.

  • Although the Norwegian Viking contribution to Orkney was distinctive, the Danish contribution to Eastern England could not be detected. This may be because of the close genetic distance between Danish Viking and some earlier Anglo Saxon settlers makes it impossible to see.

  • Although there was no “Celtic Fringe”, the Welsh appear to be closest to the late prehistoric British population.

  • Any Iberian contribution appears to be tiny and insignificant.

  • There appeared to be a contribution in Southern Britain, particularly in Cornwall, from a population shared today by the North French. This contribution appears to have occurred during late prehistory and is historically unknown.

Okay, so that is suggesting a diversity across the British Isles that extends into Prehistory. A key finding to this thread is that it found the English to be an admixed population, with earlier British ancestry dominating Anglo Saxon ancestry from the Continent.

Finally, I think it is worthwhile bringing up another recent study:

Iron Age and Anglo Saxon Genomes from Eastern England. Schiffels, Haak, etal. 2015.

This qualitative study focused on ancient DNA from a number of Iron Age and Anglo Saxon cemeteries in the Cambridge area of SE England, referenced against modern populations.

Key points.

  • The East English derive 38% of their ancestry from Anglo-Saxon immigrants

  • The closest genetic distances on the Continent between the Anglo Saxon settlers and present day Europeans was to the Dutch and Danish.

  • They found evidence of admixture and intermarrying. Individuals with both Iron Age British, and Anglo Saxon ancestry.

  • People of Iron Age British ancestry were adopting and embracing Anglo-Saxon culture and grave goods.

  • The richest graves were of local Iron Age British ancestry (with Anglo Saxon cultural artifacts). The poorest graves were recent Anglo-Saxon arrivals.

My conclusion:

  • We have to be careful about who we regard as the Celts. A Celtic culture did exist, but it wasn’t necessarily brought to the British Isles and Ireland by an Iron Age people. It may have developed on the Western Atlantic Seaboard from earlier Bronze Age peoples.

  • Those Bronze Age peoples, predominantly descended, from Eurasian Steppe Pastoralists, that had swept across Europe, bringing innovations. They are the oldest peoples of Ireland and the British Isles, but they did not form a homogeneous Celtic Fringe. There must be more to it.

  • The Anglo-Saxon event in SE Britain was a major and significant migration. However, it was not the genocide of Bede's claims. Hengist and Horsa were clearly mythological origin characters akin to Romulus and Remus.

  • The modern day English are an admixed population. They have a foot both in earlier British ancestry, and in Anglo-Saxon / North Sea migration.

On the Trail of our Y Ancestor

Early examinations of the Chandler / Brooker Southern English L-M20 Y haplogroup samples, seem to be suggesting that they share a common ancestor quite recently, perhaps between 300 and 600 years ago.  That might mean that a Y ancestor carried the haplogroup into England, perhaps between the 13th and 17th centuries AD.

Where did that Y-DNA come from?  It could have been carried directly by one Y ancestor from a homeland, or it could have transported to England gradually over many generations, from a homeland in Western Asia.

An early match has been forwarded by Caspian, forum user at Anthropogenica.  It is a 111 STR marker, from Birjand / Southern Khorasan, in Eastern Iran.

Could this be the home of our Brooker family Y ancestors?  That is to say, if I was to trace my father, back to his father, to his father - and to continue along this route, might I eventually find my ancestors on this paternal line, in Eastern Iran?  It's an early possibility.  More data, more tests, might eventually give me a better answer.

Edit. 25th May 2016

Early analysis by Gareth Henson, informally suggests a tmrca (time since most recent common ancestor) between myself and the guy in Eastern Iran, of circa 3,000 years ago, or if you prefer, 1000 BC. That would mean that we shared a common lineage until around the time of the Later Bronze Age in British terms. Our common  Y ancestor most likely lived nearer to his home in Western Asia than to mine in North West Europe. 

That isn't long ago. It might suggest that our most recent common ancestor lived in Western Asia around about the time of a series of tensions and conflicts  between Greeks and Persians.  On the other hand, Anthropogenica user Anabasis, using the Clan McDonald TMRCA Calculator, suggests a more recent date, around 1,800 to 1,500 years ago.  That in his words puts it into a context of "In that times Roman - Sasanian wars happened along Eastern Anatolia. Greek- Persian wars were 1 millennium earlier.".  However, he warns, that STR data is not a trustworthy indicator of a TMRCA.

What I love though, is that it stirs the imagination.  Whether 1,500 years ago, or 3,000 years ago - I, an East Anglian, had a paternal ancestor somewhere most likely, between Eastern Anatolia, and Afghanistan.
