Recently I was sent a complimentary test by a new British ancestry DNA company, Living DNA.
The company, based in Frome in Somerset, has just launched in the UK, but is working with experienced mathematical genomicists like Professor Simon Myers of the University of Oxford (one of the team of academic researchers (https://www.gensci.net/) from various UK universities who in partnership with Living DNA developed the autosomal ancestry test) to help interpret customers’ results.
“This is a whole new approach to DNA ancestry testing, and it is highly personal. No other method – either in scientific literature or in the field of personal genomics – can identify the ancestry of a single person to the level of regions within the UK.”
Dr Dan Lawson, University of Bristol
As such, Living DNA claims to have developed the world’s first DNA test which allows people to break down their British ancestry to any of 21 regions in the UK, and that shows how their worldwide ancestry from 80 population groups has evolved over history.
The 21 regions covered are:
- Aberdeenshire – Aberdeen and the surrounding areas of Northeast Scotland
- Central England
- East Anglia
- North Wales
- North Yorkshire
- Northwest England
- Northwest Scotland
- Northumbria – “a unique genetic signature that can be detected within the region today”
- South Central England
- Southeast England
- South England
- Southwest Scotland and Northern Ireland – “There is a shared genetic signature for the areas now known as Northern Ireland and the Southwest of Scotland, including Dumfries and Galloway. The areas are divided by a watery barrier, yet historical migrations across the sea have led to a shared genetic legacy between them.”
- South Wales Border
- South Wales
- South Yorkshire
This test uses the latest GSA Illumina chips, and their algorithms have been developed in partnership with members of the team behind the landmark People of the British Isles study of 2015. Living DNA is keen to stress that this is a geographic test, focusing on where people have lived, rather than on ethnic diaspora/population community groups such as Jewish Askenazi.
The aim of the project is to show how we are all connected and the company is keen to use DNA testing to help combat racism by demonstrating that race is only socially constructed – there is not genetic foundation for the concept of race. To that end, the company is working in schools on projects with Show Racism the Red Card.
“Compared to other ancestry tests out there, Living DNA is like viewing your family history on a high definition TV. By combining the latest DNA testing technology with the most robust academic research, we can give users the most accurate picture of their estimated ancestry.”
David Nicholson, managing director, Living DNA
Claiming to be the most academically robust on the market, the test does not use admixture but examines the way DNA is linked together. The aim is to bring academic work to individual consumers around the world, including family historians. As the test is new, results will be updated continually and results amended over time. This is particularly the case for areas where samples are currently low, such as with the area of southern Ireland.
For my test, I did not need to send a DNA sample. I simply submitted my raw data (taken from a prior genetic genealogy test). The test works autosomally, reading from the 22 of the 23 chromosomes that make up each person’s DNA using technology based on the Living DNA Orion chip (comprising software and unique reference databases). Autosomal DNA is inherited randomly from our ancestors, meaning that siblings can show a different inheritance in this test. One brother may have inherited more DNA from a Welsh 4x great grandmother, for example, than his sister. Thus the test provides a unique insight into each individual’s geographic inheritance.

Professor Myers told me that while the team is able to quite precisely identify regional contributions within the British Isles, the genetic differences they are identifying are also very subtle. Most people’s ancestors are likely to come from a more geographically diverse set of locations in the 6-10 generation period than are exactly traceable using genealogies. In general, it’s harder to precisely pin down contributions that make up only very small amounts of DNA geographically, because they give less data for analysis.
On first glance, my results make sense compared with my known ancestry. They indicate that I have 90.7% British Isles DNA, which matches roughly with results from other autosomal tests.
In comparison, my Ancestry test indicated 85% Great Britain, Family Tree DNA suggests 72% British Isles, while DNA Land has me as 76% Northwest European (which covers Scottish Argyll_Bute_GBR and British in England; Icelandic in Iceland; Norwegian in Norway and Orcadian in Orkney Islands).
Within the Living DNA’s 90.7% British Isle results, my genetic breakdown is as follows:
- South Central England 18.2% [update Aug 2017: 19.3%]
- Central England 14.3% [update Aug 2017: 4.5%]
- South Wales Border 9.8% [update Aug 2017: 23%]
- North Wales 9% [update Aug 2017 8.8%]
- South Wales 7.6% [update Aug 2017: 9%]
- Northumbria 6% [update Aug 2017: 5.5%]
- Cornwall 4.7% [update Aug 2017 4.3%]
- East Anglia 4.4% [update Aug 2017 2.3%]
- Devon 3.6% [update Aug 2017 2.5%]
- Northwest England 3.2% [update Aug 2017 2.5%]
- Southwest Scotland and Northern Ireland 2.6% [update Aug 2017 2.7%]
- Cumbria 2.6% [update Aug 2017 2%]
- Orkney 1.6% [update Aug 2017 1.4%]
- Aberdeenshire 1.1% [update Aug 2017 2.8%]
- British Isles (unassigned) 1.8% [update -]
- Southeast England [update Aug 2017 1.3%]
As I have recently been learning Welsh in order to help with family history research (as well as visits to Wales), I was pleased that, according to these results, the Welsh contributions adding up to 26.4% indicate that I am 1/4 Welsh. In these results, the “Welsh borders” also includes some English regions bordering Wales (such as Shropshire where I have known ancestors). However, Professor Myers clarified that usually, Welsh ancestry is not mistaken for other places. 5/32 of my 3x great grandparents were born in Wales. Others may have had Welsh ancestry which has been picked up autosomally. [August 2017 update: my Welsh contribution now adds up to a whopping 40.8%. It remains to be seen how much of this is from the English border counties . . . ]
Description of the Central region from the Living DNA website.
Regarding my ancestors from Central England, this area seemed a bit vague. The description references Mercia, which in the past included Staffordshire, Worcestershire, Warwickshire and Shropshire. Of my 32 3xgreat grandparents, 15 were born in this region. The test broadly divides Central England into two zones, one more Northerly and one more Southerly.
I was a little confused by the definition of the “S. Central England” region (which would also include Gloucestershire, Somerset, Oxfordshire etc.), as I do not have any recent ancestry from those counties. However, Professor Myers told me that Wiltshire, where 2 of my 3xgreat grandparents were born, heavily overlaps and they would expect/hope for ancestry from Wiltshire to be attributed to this region (and sometimes also to S. England). I told him that I had ancestry from Hertfordshire and Bedfordshire, also, and he suggested that this might contribute more to the N. Central England region, but that as these regions are neighbouring and also extremely similar genetically, some overlap is expected.
Two of my 3xgreat grandparents are from Norfolk and my genetic connection to them has been proven through another genetic DNA test. East Anglian DNA is very similar to that of Germany – indicating that of all the British regions, this is the most Anglo-Saxon. Others contain the presence of Vikings, Jutes, Danes, Normans and, of course, Celts. Although, my East Anglian results are only small here, they fit with the small percentage contributed by these Norfolk ancestors. Professor Myers explained that as my Norfolk-born great, great grandmother, Maria Pymer Jolly, is separated from me by four generations of random inheritance (or non-inheritance), this means I won’t always get exactly 6.25% (the percentage presented by a 2x great grandparent) of DNA from her. She might genuinely have only given me 4-5% of my ancestry – with other ancestors being over-represented instead. He went on to say that the test is not *so* precise currently that the proportions for these small contributions are exactly accurate.
For me, the oddest results were those indicating that I have ancestry from Cornwall and Devon. I wondered if within the 10 generations, I might have South Western ancestors who moved the relatively short distances north to Wales or Wiltshire. Plymouth in Devon, but on the border of Cornwall, is just 143 miles from Devizes, where one of my 3x great grandmothers was born, for example. Newport in south Wales is just over 60 miles away from Devizes. Professor Myers agreed that this interpretation of local movements seems very sensible, as the test is reasonably confident there is some ancestry from these regions at some point.
For the 1.8% unassigned (British) ancestry, he explained that this means Living DNA thinks the ancestry is from the UK, but in their evaluation of uncertainty in my results (where they essentially reanalyse my genome after “resampling” its parts, a standard statistical approach) this 1.8% could not be confidently pinned down geographically. After a second look at the data, Professor Myers said his “best guess” for the 1.8% is actually Southern England, which could fit with my Wiltshire ancestry.
My 2x great grandfather, William Jolly, was born in Montrose, Forfar (now Angus) but his parents were from Kincardineshire, which Living DNA places in Aberdeenshire and/or Northwest Scotland as it falls right at the border of the two different regions). It is possible that the evidence of ancestry in South west Scotland & Northern Ireland, Orkney, Aberdeenshire, and possibly Cumbria, all comes from this part of my family tree.
There is still more research to be done on my tree by more and more analysis by Living DNA on my genetic data. However, the results so far appear to be a positive start to understanding my British genetic ancestry.
Living DNA goes on to say that, “If you know anyone that’s already taken a DNA test they can upload their DNA for Free and will benefit from a new type of DNA Matching in mid 2018. . . DNA Matching is in final stages of testing for Living DNA clients, we are still aiming to get this live by the end of the year. People taking part and uploading their DNA for free don’t get the regional UK breakdown just DNA matching when live and all the other things that will come out of the project. Therefore it’s not a substitute for a Living DNA test.”
