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.

K36 Timeline - Ancient Ancestry

This new DNA tool can be found here.  It's just a little bit of fun.  It requires results from your DNA test results run through the Eurogene K36 calculator (available on GEDmatch).



15,000 years ago (Upper Palaeolithic - LGM):


Total Europe 81%
including:
Hunter-gatherer North & East 71%
Hunter-gatherer South 10%

Anatolia 19%

I've previously explored my Ancient Ancestry from this period in the post Celebrating my Ice Age ancestors.





4,500 years ago (Late Neolithic / Copper Age):

Indo-European Expansion 70%
European Farmer 28%
Local European HG 1%

Anatolian Copper Age 1%

I've previously explored my Ancient Ancestry in the two posts Celebrating my Neolithic Ancestors and Celebrating my Steppe and Beaker ancestors.

Review

As with any ancient DNA calculators, this shouldn't be taken as a serious result, but as a fun approach, to compare results with others.  It's great that as enthusiasts, we can now start to explore our ancient admixtures for ourselves.  Compared to CARTA:

From CARTA 2016.

The results look a little weighted towards the "Indo-European" (Copper Age Steppe Expansion), and this repeats when compared with my other ancient calculators.  I suspect that my actual European Neolithic (Early Farmer) percentage is a little higher than 28%, and my IE rather lower - but it's all just fun.

In addition, I'd still stay clear of labelling the Steppe Expansion as "Indo-European" or entering the linguistic debate.  Finally, the 15,000 year old map.  I think that it plays down some of our ancestry from Asia north of the Caucasus, or at least Eurasia, and would be better labelled Western Eurasia than as Total Europe.  My Y line proves that I have some Ice Age ancestry from SW Asia, from the area of Iran.  Of course, this is the issue with any test on autosomal DNA, it's going to rock around, even between siblings, due to each random recombination.

However, an excellent tool, thank you to the creator.


Celebrating my Ice Age ancestors

Ice Age Genealogy

The MDLP K11 Modern and K13 Modern calculators were released on Gedmatch.com today.  I thought that I'd celebrate by taking the opportunity to post more on ancient origins, as suggested by personal DNA calculators.

The below calculators do sometimes conflict.  Perhaps they are a long, long way from perfect.  However, one issue is that they tend to be built to look at different populations, and a different times.  Nonetheless, I feel that they are starting to tell us something.

A major revelation to myself, is that go back, say towards the end of the last Ice Age, 13,000 years ago, and the ancestors of this present day Englishman were scattered in the most unexpected places, over a wide area.

My Y ancestor at the time was most likely an ibex hunter in the area of Iran and Iraq, possibly in the Zagros mountains.  My mitochondrial ancestor, was most likely a woman in a band of hunter-gatherers in Central or Western Asia.

most likely at that time, had mammoth hunting ancestors in Siberia (Ancient North Eurasian).  I had hunter-forager ancestors in the Middle East or Arabia (Basal Eurasian).  I may have had ancestors in the Caucasus themselves.  I may have even had some hunter-gatherer ancestors in Southern Europe.

My Ancient Ancestors 13,000 years ago, were most likely, scattered in small hunter-gatherer bands, from Southern Europe, across to Central Asia, and from Siberia, down to Arabia.  That's the Late Ice Age ancestry of this Englishman.  I'm a Eurasian.  The idea that my Upper Palaeolithic ancestors were cave men in the British Isles, or even in North-West Europe, is an illusion.

The other factor is that, perhaps in slightly different percentages - all Western Eurasians today share the very same Ice Age ancestors - English, Iranian, French, German, Pakistani, Spanish, Armenian, Russian, or Norwegian.  We are all pretty closely related cousins in one post Ice Age family, that has literally exploded with agriculture, then industrialisation.

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.

Alternatively, the FT-DNA test, although many in the population genetics community feel that it is unreliable:

Visit to Lowestoft Record Office

The Barber Family of St Michael, South Elmham, Suffolk

I recently found evidence that my ancestor, 3xgreat grandfather Robert Barber of St Michael, may have been the Robert Barber of Suffolk that was transported in 1844.

I also made contact via GEDmatch, with the owner of a sample that shares 56 centiMorgans of DNA with my sample, including a 27 centiMorgan segment.  It is all on my late father's side.  This is by far the most significant DNA match that I have yet encountered on GEDmatch.  Email correspondence with the owner (Margaret), revealed that we share a paper trail, with the Barber Family of St Michael.

The trail follows my father's maternal side.  His mother's mother, was born Emily Barber, at Hedenham, Norfolk in 1859.  Her father was George Barber, born at St Michael in 1830.  George was a son of Robert and Mary Ann Barber.  I thought that Robert was baptised nearby at Alburgh, Norfolk, the son of George and Hannah Barber (nee Blaxhall).  I thought that Mary Ann was baptised Maria Page, daughter of John and Mary Page (nee Brooks), and that she married Robert at All Saints, South Elmham, in 1828.

However, making contact with a DNA relative challenges an insecure tree.  Margaret pointed out a nearby Robert and Maria Barber family.  I started seeing more Robert Barbers, more Marys, More Marias.  Online digital records for Suffolk are not as good as they are for Norfolk. Confusion!  This is an example where Online Genealogy falls down.

So I checked with the Archive branch of the Suffolk Record Office had the original St Michael records - should no microfilms or fische be available.  They were over at Lowestoft.  Yesterday I drove over, to strike the iron while it was still hot.  I was quite pleased with the resources in the office.  I did not have an excuse to request the original registers - although digital is lacking, they have good copies on fische and film.  In addition, the Saints Villages of South Elmham had all been indexed and typed up by volunteers.  So what did I find?

The baptism font in St Michael's, South Elmham, Suffolk, yesterday.  This would have been used in the below baptisms of ancestors.

There were a LOT of Barber families in the area, since the parish registers start in 1559.  The very earliest reference is to a baptism at St Michael's, of a Robert, son of Robert and Brigett Barber xxxi Auguste 1589.  A lot of sons born in St Michael alone during the following century - this was going to be difficult.  Indeed, in the St Michael registers, Barber entries continue on a regular basis until 1713.  Then a break!  No doubt there were a lot of Barber families living in the surrounding parishes and district, but the next St Michael Barber entries start with our family in 1818:

Baptisms St Michael's, South Elmham

  • Lydia, daughter of Robert & Mary Barber (born Dec 11) Husbandman. Bap. 19 Dec 1818.
  • Emma, daughter of Robert & Mary Barber, husbandman. Bap. 28 Apr 1821.
  • Isaac, son of Robert & Mary Barber, husbandman.  Bap. 14 Jan 1823.
  • Maria, daughter of Robert & Mary Barber, labourer.  Bap. 3 Jun 1827.
  • Charlotte, daughter of Robert & Mary Barber, labourer.  Bap. 25 Nov 1827.
  • George, son of Robert & Mary Barber, labourer.  Bap. 11 Apr 1830.
  • Eliza, daughter of Robert & Marianne Barber, labourer.  Bap. 7 Apr 1833
  • Jacob, son of Robert & Mary Barber, labourer.  Bap. 6 Nov 1836
  • Jacob, son of Robert & Mary Barber, labourer.  Bap. 18 Sep 1843
  • Emily, daughter of Robert & Mary Barber, labourer.  Bap. 18 Sep 1843

Maria is Margaret's ancestor, George is my ancestor.  I am a little confused as to why there might be two Jacob's, perhaps the first died, but I'm not sure.  I did find a later burial of a Jacob Barber age 23, who died after falling from a moving horse pulled wagon.  However, the clumsy genealogist in me didn't record the date!  Note also that the last two baptisms were joint.

I could not locate the marriage of Robert Barber to Mary (Ann).  This was a disappointment.  I did look through the other Saints Villages of South Elmham.  Neither did I find or confirm Robert's birth.  I had previously online found a baptism at Alburgh, Norfolk - a close by parish, just over the river.  however, as Robert claimed that he was born in Suffolk on the 1841 census, I have deleted that link from my tree.  Another case, where I lost more ancestors from the tree, than I gained from this research.  however, the point of genealogy is to improve and refine, based on evidence.

I do believe however, that I have located Robert's death.  I have also eliminated him as the transported Robert Barber of Suffolk.  I found the below burials:

Burials St Michael's, South Elmham

  • Robert Barber, aged 8 days.  Bur. 19 Aug 1840
  • Robert Barber, aged 50 years.  Bur. 22 Feb 1846
  • George Barber, aged 20 weeks of St Peter's.  bur. 30 Dec 1860
  • Eliza Barber, aged 6 days.  Bur. 22 Jun 1862.

The baby Robert, could have been Robert and Mary's.  The fifty year old Robert Barber, does look like my 3xgreat grandfather.  Indeed, it explains where he went between the 1841 and 1851 census.  He was not transported.  Checking Suffolk criminal records at the Record Office, I found that the 1844 sentence of a Robert Barber was over in West Suffolk, at Bury St Edmunds Assize.

I had jumped the gun again - based on the very partial online record.  I keep learning this lesson, but it should also serve as a lesson to genealogists abroad, that rely only on digitalised or transcribed records of English ancestors online.  What you are seeing is a partial record.  There can be so many John Smiths, or even Robert Barbers, in a small area. A visit to the County Archive (Record Office) revealed so many more records of Barbers in the South Elmham area, that cannot be seen online at Ancestry.com, FindMyPast.com, nor on FamilySearch.org.  Beware!  I see awful, incorrect family trees (not just my own ha ha), whenever I view personal online trees at Ancestry.com.

The Tovell Family of Wrentham, Suffolk

While I was at Lowestoft, I thought that I would take a quick look at another ancestral family of mine, local to this Archive.  The Tovell Family that lived at Wrentham, Suffolk, during the late 18th Century, and fall on to my mother's side of my family tree.  Although members of a local Congregationalist chapel, for some services, they referred to the local parish church.  It was in a transcript of those parish registers, that I found a number of burials of the children of my 4xgreat grandparents Tovell:

Wrentham, Suffolk Burials

  • Thomas Tovell, an infant.  Bur. 29 Jan 1773
  • Elizabeth Tovel, an infant.  Bur. 29.Mar 1778
  • Sarah Tovel, infant.  Bur. 13 Jan 1780
  • Thomas Tovell, an infant.  Bur. 31 Dec 1782.

They went on to have a third son baptised Thomas Tovell in 1785, who was my ancestor.  Sometimes though, the infant mortality of those times can get to you.

Genealogical updates - 3rd Feb 2017

Above photo of Emily Smith (nee Barber) and her son Sid Smith (a First World War veteran) in Norwich, Norfolk.  Emily was born at Hedenham, Norfolk in 1859, and was my late father's maternal grandmother.  In the 1871 census, she was recorded as an 11 year old crow keeper.  Emily went into service in Norwich, where she met my great grandfather Fred Smith, a wheelwright born at Attleborough, Norfolk.

New Gedmatch

I've recently had two genetic matches that actually work out in the form of documentary evidence.  the first came via FT-DNA Family Finder, when I was approached by an Australian genealogist, who it turns out, is the fourth cousin of my mother, via the Thacker line.

Then over the past few days, I spotted a new kit on GEDmatch, that shared 56 cM, with the longest segment at 27 cM.  It is on my father's side, no match to my mother's kit.  My closest ever GEDMATCH.  It's early days, but a quick comparison on our documentary records show a documentary match.  We both descend from a Barber from the hamlet of St Michael, South Elmham, Suffolk.  Gedmatch puts us at four generations apart, but I suspect a few more.  I feel a need to visit St Michael and the Suffolk Record Office to clear this family up.  Only a week ago, I discovered online that my 3xgreat grandfather Robert Barber of St Michael, may have been transported by the Suffolk Assizes to Norfolk Island, and onto Van Diemen's Land (update: See next post - he was not!).

I still had more success with "expanding" my family tree by contacting genealogists back in the old days, by surname interests listed in the annually printed GRD (Genealogical Research Directory), or in monthly genealogical magazines.  However, there is something fascinating about discovering distant relatives by comparing chromosome browsers online.  To think, and to see those shared DNA segments is very cool.  It shows how little bits of personal DNA filter down, often to unknown people in the street, with no idea of relationship.

Thacker News

I received another commissioned certificate from the GRO (General Registry Office UK).  I didn't waste money, it belonged to an ancestor - Susannah Thacker, a 3xgreat grandmother.  She was born at Salhouse, Norfolk in 1823, to an anabaptist family of agricultural labourers.  She had given birth illegitimately to my 2xgreat grandfather George Thacker in 1847.  After that, I had no idea where she went.  Her son George Thacker, was brought up at Rackheath, Norfolk (next to Salhouse) by his grandparents.  He recorded Susannah Thacker in the father entry of his marriage registration.  Until I saw that, I only knew her from census data as Susan Thacker.

I recently searched online for her, I wanted to know where she went.  I only found index references from the GRO.  I ordered.  Now I know that in fact, she left her son George with her parents, but went on to marry a widower, a Samuel Birch, at the Norwich Registry Office in 1855.  They lived in Norwich.  That seems good.

George Thacker with his wife Sarah (nee Daynes) circa 1877.

Genealogy - why?

Anyone that loves a who dunnit, or a crime novel, should love genealogy.  It is all about detective work.  looking for clues and evidence.  Collecting it.  Answering mysteries - even as mundane as "what happened to the Peach's of Maxey" (the father was transported for stealing cattle), or where did my 3xgreat grandmother go?  Awesome stuff.

Gedrosia and our DNA

Attribution: Fielding Lucas, Jr. [Public domain], via Wikimedia Commons

This post is partly an excuse to upload and store the above creative commons image.  My Y-DNA terminal SNP (L-SK1414) twin was a Balochi speaker in Makran, SW Pakistan.  In classical times, Makran was located in the Kingdom of Gedrosia.  It's almost ironic that an open source range of autosomal DNA testers on GEDmatch have been named after Gedrosia.

Gedrosia was a dry, mountainous country along the northwestern shores of the Indian Ocean.  The indigenous name for Gedrosia is thought to have been Gwadar.  It was conquered by the Persian king Cyrus the Great (559-530 BC). The capital of Gedrosia was Pura, which may survive today as modern Bampûr.  In 326 BC, The Macedonian king, Alexander the Great disastrously crossed the Gedrosian Desert, on the return from his campaign in India, and lost 12,000 of his men to the savage conditions.

So, although the GedrosiaDNA GEDmatch heritage calculators may have little to do with the legendary land that may have been host to my Y ancestors, out of interest, how do our atDNA test results tally with the GedrosiaDNA calculators?  These calculators are designed to measure Ancient Eurasian Admixture.

Conclusions

We both appear to have inherited around 40% of our DNA from ancient Western (European) Hunter-Gatherer populations, nothing unexpected there.  Western Hunter-Gatherers not only lived in Europe, but appear to have contributed to some later Eurasian populations such as the Yamnaya and Early European Farmers.

We both have low counts of Ancient North Eurasian - particularly my mother, who scores only 19% ANE (Upper-Paleolithic genomes from the Lake Baikal region of Siberia, identified as Malta, Afontogora 2, and Afontogora 3, dated to 17 to 24 kya).  It has been noted during online discussions, that the English appear to have slightly lower percentages of ANE than do their close neighbours.  ANE is sometimes used to indicate Yamnaya ancestry (ANE was a component), that spread from the Eurasian Steppes into Western Europe during the Early Bronze Age.

I have 3% Balochi compared to 1% Balochi for my mother.  It may mean nothing, but it could just perhaps indicate something in the autosomes that associates on my paternal side with my Y-DNA story.  The indicators (particularly K15) suggest that I have more SW Asian ancestry, presumably from my paternal side - again, it just could associate with what we know about my Y haplogroup L-SK1414.

We have around 24-25% Early European Farmer ancestry, representing early Neolithic descendants of an admix of WHG and "Basal Eurasians".  This signal apparently peaks around 80% in modern Sardinians.  However, the "Natufian" reference are higher - 38-39%.  According to GEDmatch: "Natufian was an Epipaleolithic culture that existed from 12,500 to 9,500 BC in the area of Israel. They were derived about 50% from an original Out-of-Africa population, referred to as Basal Eurasians. If you are a European and show Natufian admixture, this does not imply that Natufians interacted with your ancestors. All it means is that Natufian like admixture was mediated to you via intermediaries, such as the early European Farmers from the Near East".  I'm not sure what to make of that.



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.
