Living DNA - June 2017 updates

Living DNA produced their first update.  An update by a "DNA for Ancestry" business can sound like an admission of failure.  To some, it could sound like a recall due to product failure.  "Your previous ancestry was a mistake".  This only applies if you have bought into some marketing campaigns, that autosomal DNA tests for ancestry actually work even close to 100%.  Surprise, they don't!  They are cutting edge, in development, and far from accurate below a Continental level. They are still somewhere in the twilight between being nothing more than a genetic lottery, and actually becoming a tool that is useful.  Therefore "updates" are to be welcomed.  They are a sign that the business wants to improve the test accuracy.  That is to the credit of Living DNA.

My latest results?  First of all, a quick recap on my actual ancestry, as supported by family history, local history, ethnicity, and by a traditionally researched record based family tree that includes over 270 direct ancestors over the past 380 years.  I'm English.  Indeed, all of my direct ancestors, appear to have been South East English.  More precise, I'm East Anglian.  On family history and recorded genealogy, I'd suggest that between 75% and 85% of my direct ancestors over the past three centuries were East Anglian, almost all from the County of Norfolk.  Others on my father's side, if not in East Anglia, still in Southern England.

That I feel, makes me an interesting subject for ancestral auDNA testing.  You see, my ancestry is very localised here in South East England.  DNA tests such as 23andMe that claim to accurately plot ancestry over the past 300 - 500 years should get me.  But they don't.  This is because their algorythms, and reference data set designs fail over different ages.  They also (although they sometimes deny it), fail to discriminate against older population background.  We East Anglians and South East English have been heavily admixed with non-British populations on the European Continent.  Not so much over the past 500 years, so much as over the past few thousand years.

The new Results.

Below is a table, comparing my recorded ancestry, with my early Living DNA results in Standard, now my revised results.

Living DNA has now introduced two new modes of confidence called complete and cautious modes.  First the Complete results:

Conclusions

No auDNA test, by any DNA-for-ancestry company has yet come close to assigning me 100% English or even British.  They don't get me.  23andMe gives me 32-37% "British & Irish".  FT-DNA gives me "36% British".  Therefore, to be fair, Living DNA, giving me 70% "Great Britain or Ireland", give me the best result.  However, Living DNA has started out with the largest, best quality British data-set of any DNA-for-ancestry company, and is often accused of a bias towards Britain in it's results.  If so, then my 70% still looks weak.  They are planning on producing similar quality data sets soon for Ireland, Germany, then France. Therefore any results, will as I started out saying at the beginning of this post, be perpetually progressive.  Businesses that do not improve data sets or algorithms, will not get any better.  They are not progressive.

I get Southern European in other tests besides this one.  Living DNA points to Tuscany.  FT-DNA before a recent update gave me 32% Southern European, although they have revised this down to a little noise from South-East Europe!  23andMe gives me 2% Southern European - but this appears nothing unusual for an English tester.  None-the-less, I am interested in trying to better understand, why some of these tests give me this "Southern European" admixture, for which my family history, local history, and recorded genealogy has absolutely no account.  It equally reflects in ancient calculators that give me a little bit more Neolithic Farmer than for other English, which on average, already have a little more Neolithic Farmer than other British or Irish populations do.

The New Complete and Cautious Modes

How do I feel about these?  At Sub-Regional level, the Complete mode starts to get silly.  For the first time, Living DNA at this level, starts to even suggest some ancestry from Wales, SW Scotland, and Northern Ireland.  Only small percentages - but I just don't buy them.

However, the Cautious Mode, I start to like.  My British ancestry doesn't increase, but it looks more realistic, although with strange enigmatic suggestions still of Italian ancestry in the mix.  At Sub-Regional level, Cautious Mode also looks a little more likely.  My East Anglian remains at 37%, I however, lose Lincolnshire (which does exist in my record), but retain Cornwall.  I think Cornwall unlikely - however, there is just a small hint that something could be there, in surname evidence of a brick-walled great great great grandparent.  So maybe, just maybe.

East Anglia

I seriously doubt that my East Anglian ancestry over the past 300 years genuinely falls much below 75%.  Living DNA only appears to recognise a half of it at 37% - but they claim to be easily able to identify East Anglian DNA.  They call it "Distinct" because of it's high levels of Continental admixture.  They have admitted that based on their early data sets, that it was hard to separate from Germanic.  I don't know why it isn't stronger in my results.  I honestly do believe that the test underplays it on my results, even though it is the strongest of any population in my test results.  My East Anglian ancestors lived mainly in Eastern, Central, and Southern Norfolk.

Living DNA also provide a chart of the Continental "contributing regions" to East Anglian ancestry:

Finally, a chart breaking down their proposal of my British ancestry at Cautious mode:

I'm not disappointed with Living DNA.  That it does identify me as 37% East Anglian is I believe, incredibly good, and far advanced over any other DNA-for-ancestry test.  I'm looking forward to more updates in the future.  Well done Living DNA.

Ancient ancestry - K11 Ancients Common and rarer Alleles, and a fresh assessment

Emmanuel Benner - Prehistoric Man Hunting Bears

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 Paper Trail and Family History

I was born in Norfolk, to a local family.  My current gedcom database includes records of 2,490 family members and ancestors for my children.  I currently have records of 279 of my direct ancestors.  All but two (a 3 x great grandfather and his named father of Switzerland) 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.

  • Brown = East Anglia, England
  • Blue = South Central England
  • Orange = Lincolnshire, England

Father's Ancestry

On my father's side, I currently have 131 of his direct ancestors recorded.  The majority were in Norfolk, but some distant ancestors on record also lived in Oxfordshire, London, Suffolk, Cambridgeshire, Northants, Berkshire, and a great great grandparent from Switzerland.  This map demonstrates his English ancestral events in his database, over the past 330 years:

Mother's Ancestry

On my mother's side, I currently have 146 of her direct ancestors recorded.  They were all in East Anglia - almost all in the County of Norfolk, with a few distant ancestors over the county border in Suffolk.  Her ancestry over the past three centuries has a particularly dense cluster in Broadland, East Norfolk.  This map demonstrates the ancestral events in her database, over the past 330 years:

Online Family Trees

Screenshots of my great grandparent's trees (2017-08-24) on Ancestry.co.uk

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 (updated July 2017)

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.

Below are my Living DNA regional ancestry, based on Standard Mode.

Below are my Standard Mode results broken down into sub regions.

Living DNA has now two new modes of confidence called complete and cautious modes.  First the Complete results:

Below are my Complete Mode results in regional:

Below are my Complete Mode results for sub-regional:

Now the Cautious results:

Below are my Cautious Mode results in regional:

Finally, below are my Cautious Mode results for sub-regional:

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.  Living DNA give me 37% East Anglia.  I predict from my recorded genealogy, that I most likely have around 75% East Anglia in reality, however, that a DNA test could even identify a half of such a small sub region is I feel very impressive.

The Tuscan percentage, I could not explain.  However, the recent discovery on record of Swiss ancestry at Generation 6 could correlate to it.  It could explain some of the enhanced (for an English tester) southern European ancestry on a number of tests.  Although most likely only responsible for 0% to 5% of my DNA, I do have a Swiss great great great grandparent.  Could he account for that percentage, or do I have an additional Southern European ancestor at around that generation, that I haven't yet found in the record?

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.

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, 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 was also impressed by the Ancestry.com / Ancestry.co.uk Genetic Communities feature, that correctly assigns me to the "East Anglia & Essex" genetic community, with "very likely" and 42 initial DNA matches within it.  In comparison, the 23andMe offering of Your Ancestry Timeline is nonsense and totally inaccurate.

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/French.  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.  Ancient admixture calculators (see further below), consistently suggest that my autosomal DNA has a slightly more South European flavour, than is average for a North west European.  I cannot account for these sort of percentages within my known recorded genealogy, other than one Swiss 3 x great grandparent.  I'm currently open minded to having other unknown Southern European ancestors within the past ten generations, either that, or it is some sort of English population background signal, perhaps related to unknown prehistoric admixture, Roman British admixture, Norman Medieval admixture, or a combination.  The randomness of genetic recombination perhaps, with an almost endogamous maternal family history set in Norfolk.

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

Haplogroups act as genetic markers that follow strict rules of inheritance, passing down only one direct line of ancestry.  They can be traced back into prehistory, and have a high reliability.

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), Azeribaijan, 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 AD 1723.  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 and Unetice Culture.  More recently H6a1a has been recorded in the Netherlands ( 1883–1665 calBCE) in Bell Beaker 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.

My K12 results and populations

ANCIENT FARMERS 58.9%

West European Farmers (4000-5000 years)  25.2%  References include Neolithic genomes from Portugal, and Chalcolithic genomes from Spain. The similarity between these farmers and other Mediterranean farmers points to a rapid spread of agriculture in Europe around 7000 years ago.

East European Farmers (5000-8000 years)  22.9%  References consist of genomes from Turkey, Greece, and other parts of SE Europe from the Neolithic period. These represent descendants of the first farmers to colonize Europe from the Near East.

Neolithic-Chalcolithic Iran-CHG (5000-12000 years)  6.7%  Based on Neolithic and chalcolithic period samples recovered from Northwest Iran. The farmers from the Zagros mountain Iran region descended from one of multiple, genetically differentiated hunter-gatherer populations in southwestern Asia.  They are estimated to have separated from Early Neolithic farmers in Anatolia some 46,000 to 77,000 years ago, and show affinities to modern-day Kurd, Iranian, Pakistani and Afghan populations.  The Neolithic Iranian references used for this component, were recovered from the Kurdistan region of Iran, and appear to be around 9000 years old. The Chalcolithic Iranian references have been dated to around 5000 years old. The Caucasus Hunter Gatherers (CHG) appear to have genetically contributed to present day Europeans, W Asians, and S Asians.

Levant (4000-8000 years)  4.1%  Based on neolithic and bronze-age period samples recovered from the Levant area in the Middle-East. The references for the bronze age Levant farmer (BA) samples were recovered from the Ain Ghazal, Jordan area and were dated to about 4300 years ago.  The first farmers of the southern Levant (Israel and Jordan) and Zagros Mountains (Iran) were strongly genetically differentiated, and each descended from local hunter-gatherers. By the time of the Bronze Age, these two populations and Anatolian-related farmers had mixed with each other and with the hunter- gatherers of Europe to drastically reduce genetic differentiation. The impact of the Near Eastern farmers extended beyond the Near East: farmers related to those of Anatolia spread westward into Europe; farmers related to those of the Levant spread southward into East Africa; farmers related to those from Iran spread northward into the Eurasian steppe; and people related to both the early farmers of Iran and to the pastoralists of he Eurasian steppe spread eastward into South Asia.

STEPPE CULTURES 30.8%

Andronovo-Srubnaya (3000-4000 years)  14.3%  The Andronovo culture, which are believed to have aided in the spread of Indo_European languages, is a collection of similar local Bronze Age cultures that flourished around 3000-4000 years ago in western Siberia and the west Asiatic steppe. This culture overlapped with the Srubna culture in the Volga-Ural region of Russia.

Yamnaya-Afanasievo-Poltavka (4000-5000 years)  10.1%  Believed to be among the first Indo-European language speakers. The Yamnaya genetically appear to be a fusion between the Eastern European Hunter Gatherers that inhabited the western Siberian steppe, and a populations from the Caucasus region. Descendants of the Yamnaya would later change the genetic substructure of indigenous Neolithic Europeans via invasions of Europe from the Eurasian steppe.

Karasuk-E Scythian (2000-3000 years)  6.4%  This cluster is based on ancient genomes from the Karasuk culture, supplemented with two Iron-Age Eastern Scythian samples. The Karasuk percentage should be interpreted as a diffusion of DNA from the Eastern Eurasian Steppe populations post Bronze Age, via Turkic expansions, as well as more subtle diffusions via NE Caucasus populations.

WESTERN EUROPEAN & SCANDINAVIAN HUNTER GATHERERS (4000-5000 years)  8.8%

These were the indiginous populations of Europe that substantially contributed to the genetics of modern Europeans. It is believed that these hunter gatherers arrived in Europe around 45000 years ago from the Near East.

EASTERN NON AFRICANS (modern)  1.5%

Eastern Non Africans are one of the earliest splits from humans that migrated out of Africa to the Near East around 100,000 years ago. It is believed that ENAs split from the population in the Near East around 50,000 years ago. Populations such as Papuans and Aboriginal Australians are modern descendants of ENAs. The ENA component here is based on Papuan and Aboriginal Australian references.

Neolithic and Bronze Age Ancestry K11 Rarer Alleles

This is the K11 admixture calculator with rarer alleles created by Dilawer Kahn, now available for a small fee as a test on Geneplaza.  I had previously commissioned Dilawer to run my 23andme DNA raw data through the calculator, but this is a nicer presentation.  The test seeks to estimate ancient ancestry admixture using his rarer alleles principle.

My results:

Western European Hunter Gatherers

It is believed that ENAs split from the population in the Near East around 50,000 years ago. Populations such as the Andamanese Onge and Papuans are modern descendants of ENAs. The ENA component here is based on Papuan references.".

My Eastern Non-African admix is 1%

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.

Brooker Surname Study

Above map modified from "© OpenStreetMap contributors".  The red dots represent baptisms of BROOKER (including derivations such as Broker, Brocker, etc) between 1550 and 1600.  The larger the red dots, the more baptisms in that parish.

The area focuses on South-East England.  There was also a secondary cluster in Warwickshire, and stray families in Manchester, Yorkshire, Devon, and Norfolk.  However, I have not catered for all of those on the above map.  See the below larger scale map for Brooker baptism counts in those areas by county.

The Blue dots and notes mark ancestral birthplaces and dates of my recorded surname ancestors in Berkshire, Oxfordshire, and Deptford, London.  My line traces back reasonably securely to a John Brooker born at Long Wittenham, Berkshire, circa 1722.

The Purple dot and text represents Thomas Chandler of Basingstoke, Hampshire.  Living there circa 1740's, he appears to have shared my Y-DNA markers L-SK1414 judging by some of his Chandler surname descendants that have tested.  At some point before 1722, we must have shared Y line (paternal) ancestors.

From this map I can conclude that during the late 16th Century, the BROOKER surname was most common in Sussex, Kent, Surrey, and Hampshire.  There was a secondary cluster in Warwickshire.

Distribution of BROOKER baptisms AD 1550 - AD 1600 by English County.  County boundaries modern, but East and East Surrey united for historical purposes.  Includes records of derivations of Brooker surname.

Surname Origin

This interesting surname derives from two possible origins. Firstly it may be of English topographical origin from the Old English word "broc", a brook, stream, plus the agent suffix "-er", used to describe a dweller at, hence "dweller at the brook". There is also a place called Brook in Kent and Wiltshire, from the same Old English word "broc" as above. Also the name may be an occupational name used to denote a broker, originating from the Anglo-French word "brocour", one who sells an agent in business transactions. The earliest recordings of the surname appear in the 13th Century (see below). John le Brouker was recorded in the 1327, Subsidy Rolls of Sussex. William le Brocker was listed in the 1326, Feet of fines Rolls. The Close Rolls in 1332, record a Elena Brocker. Kirby's Quest for Somerset recorded an Adam Brocker in 1328. Geoffrey Broker, aged 17, an immigrant to the New World, sailed aboard the "Merchant's Hope", bound for Virginia in July 1635. The first recorded spelling of the family name is shown to be that of William Brokere, which was dated 1296, Subsidy Rolls of Sussex, during the reign of King Edward 1, "The Hammer of the Scots", 1272 - 1307. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.

A DNA Reference for East Anglian Ancestry

GEDmatch Kit M786040

 The above map of East Anglia, plots the ancestral events from my Gramps genealogical database, for my mother's ancestry alone.  All 100% of the events in her family history occur in East Anglia, with a significant concentration on the loam soils of East Norfolk, north of the River Yare, and shouldering up to the marshes of the Halvergate Triangle.  It includes events for the immediate families of 127 direct ancestors, stretching back to the 1680's in places.  Events include such things as births, baptisms, marriages, burials, deaths, census records, occupations, residence, etc.

Surnames include: Tovell, Tovil, Tammas, Tovell-Tammis, Lawn, Gorll, Gaul, Rowland, Dawes, Curtis, Key, Goffen, Goffin, Waters, Merrison, Morrison, Smith, Dove, Porter, Springall, Thacker, Daynes, Daines, Quantrill, Wymer, Rix, Hagon, Page, Nichols, Nicholes, Shepherd, Ransby, Briggs, Barker, Rose, Brooks, Larke, Dingle, Annison, Britiff, Symonds, Sales, Jacobs, Yallop, Moll, Hewitt, Osborne, Ginby, Ling, Briting, Hardyman, Hardiment, and Norton.  Surnames are all English or of Anglo-Danish origin.

Recorded religions are: Anglican Church of England, Baptist, Congregationalist (Presbyterian), Methodist, and Weslyan Methodist.  No Roman Catholicism, Islam, or Judaism.

The area has no significant immigration events in recent centuries, however, it has long held connections with the Dutch.  It is not near to the drained Fens (to the West of East Anglia), so would not have attracted any significant immigrant labour.  The City of Norwich has had communities of strangers, including medieval Jews, and more substantially, protestant refugees during the 16th century, from the Netherlands.   French Huguenots followed to Norwich.

The best known immigration to East Anglia, took place during the 4th to 11th centuries AD, from across the North Sea.  The elites of the Anglo-Saxon kingdom, claimed descent from the Angles, from Angeln  in the Schleswig-Holstein region of Northern Germany, that borders Denmark.  The area is rich in Anglo-Danish place-names.  East Anglia fell deep into the Dane-law.

The above photograph is of the wedding of my mother's parents, at Limpenhoe, Norfolk, in 1932.  It includes four of my great grandparents, and a great great grandmother.

I like to present my mother's heritage as a good reference for an area of particular interest.  An area that saw substantial early medieval immigration and admixture, from across the North Sea.  23andMe reports our haplogroup as H6a1.  Uploading the raw data to James Lick's mthap analyser, and to WeGene, both give a best match of H6a1a8.

That so much of her recorded ancestry, is so deeply rooted into East Anglia over the past 330 years, and particularly that one part of Norfolk, would suggest that she has strong East Anglian ancestry stretching back at least to the early medieval, and perhaps earlier.  I have recorded marriage between third, and second cousins, within her East Norfolk direct ancestry.

I have plotted my ancestral places that are tagged in my Gramps genealogical GEDCOM database.  These Places represent events -births, baptisms, marriages, or residence, etc.  These Places  belong to my direct ancestors, although they may also include siblings of ancestors.  Overall, I have modified this map in order to illustrate the distribution of my East Anglian (almost entirely of the County of Norfolk, with a few over the border in Suffolk) ancestors over the past 350 years - as so far revealed by paper genealogical research.

The BLUE markers represent the places of my father's recorded ancestors.  The RED markers represent the places of my mother's recorded ancestors.  The more events recorded for any place, the larger the marker.  You can click on the image in order to see a full resolution image.

The RED markers include pretty much all events for my mother's ancestors, as presently recorded in my family history database.  She has no recorded ancestry from outside of Norfolk, for the past 350 years.  She has an incredibly strong Norfolk ancestry.  Particularly in the East of Norfolk.

The BLUE markers do not cover all of my father's recorded ancestors, as I have also detected ancestry for him in Oxfordshire, London, and possibly Lincolnshire.  These ancestors lived outside of the mapped area.

When my mother and father initially met each other in 1956, they believed that they came from quite different parts of Norfolk, from opposite sides of the City of Norwich, with my father moving from East Dereham to my mother's neighbourhood in the Hassingham area.  Yet this map suggests that over the past 350 years, some of their ancestors have lived much closer.  The chances of them both sharing common ancestry during the Medieval, or even more recently are good.

This might support the findings of the POBI (People of the British Isles) 2015 study, that not only emphasised the homogeneous nature of the English, but also suggested that the old Anglo-Saxon kingdoms could still be detected as localised gene pools to today.

I have previously created the below map, using red dappling to mark out the main zone of my mother's ancestry, onto a map of East Norfolk, as it would have appeared during the 5th Century AD, before sea levels fell, and drainage works created the more recent Norfolk coast:

My hypothesis is that my mother's ancestors clustered in an area of East Anglia, that would most likely have experienced an influx of North Sea immigration between the 4th and 11th centuries AD from Frisia, and perhaps Angeln and Denmark.

I also modified the below map from Wikimedia Commons.  Attribution is: By Nilfanion [CC BY-SA 3.0 (http://creativecommons.org/licenses/by-sa/3.0) or GFDL (http://www.gnu.org/copyleft/fdl.html)], via Wikimedia Commons.  This map, as the legend states, illustrates the distribution of my recorded direct ancestors (bother on my father's and mother's sides are in RED) across the wider area of England at a single generation level, based between 1756 to 1810.  It suggests a combined ancestry, concentrated in Norfolk, East Anglia, but with a few lineages in Wessex / Mercia.
