Journals of a Time Traveller

You might think that following my recent posts, that I've lost all faith in DNA testing for Ancestry.  Not at all.  I just object when people take the analysis results of autosomal DNA tests for ancestry, as infallible truths.  They are clearly not.

So far this year, I have commissioned two 23andMe tests, and three FT-DNA tests, a FullGenomes analysis, and a YFull analysis.  I have also used free analysis at WeGene and DNA.land, and have run three raw files on GEDmatch calculators.  You'd might also think that I've done enough testing for one year!  I thought that as well.  Then a new service just entered the market.

Living DNA Ancestry attracted my commission on two particular points.  1) it has an incredible British reference, that promises to break ancestry composition into 30 British regions - in addition to global analysis.  If it works, then this is a must for people with significant British ancestry.  2) it uses the latest cutting edge test chip.  The latest Illumina chip based on Global Screen Array (GSA).  In addition, it uses a European based lab (Denmark), it tests Y-DNA, mtDNA, and autosomes.  It tests more SNPs on all three counts, than other current chips used by competitors offering autosomal plus tests.  Raw files for the test results will be available for download.

The British Reference

Living DNA will be using a British reference broken down into an incredible 30 regions, across England, Scotland, Wales, Orkney, and Northern Ireland.  The reference uses the much heralded POBI (Peopling of the British Isles 2015) data set.  This project collected 4,500 blood samples from people that could claim four grandparents in the same area, from across the regions of Britain.

A little about the POBI project below:

The British reference does not include the Republic of Ireland.  However, LivingDNA are confident that they have collected a good global reference, and I understand, that they are seeking a similar quality Irish data-set for the future.  

In comparison, other providers of DNA tests for ancestry, only reference to Britain, or the British Isles & Ireland, as a single reference point.  And as can be seen by my previous posts, with limited success.

They also hope to provide imports for formats of raw file from other test companies in the future.  LivingDNA do not themselves currently offer relative matching, or health information.  Their service is for now, primarily for ancestry.

The Chip

They will be using a custom version of the latest Illumina chip technology, the Global Screen Array (GSA).  It is encoded with:

650,000 autosomal DNA SNPs

20,000 Y-DNA SNPs

4,000 MT-DNA SNPs.

In comparison for example, the 23andMe V4 chip scans for:

577,000 atDNA SNPs

2,329 Y-DNA SNPs

3,100 MT-DNA SNPs.

I hope that LivingDNA will also use up-to-date haplogroup nomenclature and information.  23andMe with their V4 chip still use very dated 2009 nomenclature.

So, let's see if this new service is any improvement to my results, compared with the hit and miss of 23andMe, and Family Tree DNA (FT-DNA).  Will they be able to identify and locate my English roots successfully?  What will the improved chip make of my haplogroups?

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.

Generation 2 has 2 individuals. (100.00%)

Generation 3 has 4 individuals. (100.00%)

Generation 4 has 8 individuals. (100.00%)

Generation 5 has 15 individuals. (93.75%)

Generation 6 has 30 individuals. (93.75%)

Generation 7 has 28 individuals. (43.75%)

Generation 8 has 26 individuals. (21.88%)

Generation 9 has 10 individuals. (4.69%)

Generation 10 has 4 individuals. (0.78%)

Total direct ancestors in generations 2 to 10 is 127.

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.
