Thread: Does LivingDNA often overestimate British DNA%?

  1. #1

    Does LivingDNA often overestimate British DNA%?

    Iím aware that this test only goes back ten generations, but seeing as we can pick up ancestry from much further back than this, does this render extremely high percentages of British dna on this test a bit inaccurate?

    It seems when other people take different tests, the % of British DNA comes out lower and more mixed. Likewise, people who donít have any known British ancestry seem to pick up random bits through LDNA. Thoughts?

    I know my ancestry fully back 5 generations and it's 100% British. Living dna gives me 100% British . I wouldn't like to say if that's accurate going back a further 150 years.

    LivingDNA gives me 9.4% British which is a bit suspicious, especially as a Finnish person. Running the autosomal data through other calculators usually gives me 0% British.

    Yes, members of the German genealogical society with well documented lines going back 1000 years have come back with results as high as 90% British Isles. I'm approximately 1/3rd German and receive 88% British Isles, 0% Germanic or French.

    Between the ongoing Irish, Scottish, Swedish and German projects we should get some clarity in future updates.

    I am an American with about 80-85 percent British isles ancestry according to my known paper trail going back about 300 years. I have tested with ancestry and my heritage who both put my British isles ancestry at about 70 percent. Both of these companies assigned me between 16-18 percent Scandinavian and 6-7 percent Southern European. I do have a small amount of documented ancestry from Sweden but nothing to explain 16-18 percent. Family tree dna put my Scandinavian at 26 percent but they are so inaccurate in general that I didnít give that much thought. Living dna put my British ancestry at 94 percent which seemed very accurate in my case. The rest of my ancestry they assigned to Scandinavia. The 5 percent Scandinavia they gave me fits better with my known ancestry. So at least in my case living dna is accurate and it is the other major companies who overestimate Northern European for people of British descent.

    Yes, I believe that it does. My results at Living DNA
    90.3% B&I
    5.5% Scandinavia
    3% Europe South (Iberia and Italy Tuscany)
    1.1% Africa Yorubaland

    My documented and verified French and German are completely missing!

    It seems they've been grouped in with Southeast England...

    For me, yes by a large measure.
    The more I learn about this DNA stuff the less I know.

    For Dad, it was a mixed bag. It did a brilliant job highlighting the same regions in the British Isles where we had known ancestors, but fell flat in missing that nearly half Dad's ancestry was from the continent (it only had him as Scandinavian and Finn/West Russian, no French, German, Belgian, Dutch, etc). Like others found, it just dumped the German(ic) into the Germanic English regions.

    For comparison, Dad's K36 and his LivingDNA:
    https://fusiontables.google.com/embe...mplt=2&hml=KML

    Europe 100%
    Great Britain and Ireland 71.1%
    Southeast England 20.6%
    East Anglia 13.6%
    Lincolnshire 12.2%
    South Central England 9.5%

    South Yorkshire 4.7%
    Cumbria 2.4%
    Northwest Scotland 2.4%
    Devon 2.3%
    Cornwall 2.2%
    North Yorkshire 1.2%
    Europe (South) 14.3%
    North Italy 11.1%
    Aegean 3.2%
    Europe (North and West) 8.2%
    Scandinavia 8.2%
    Europe (East) 6.4%
    West Balkans 2.6%
    East Balkans 2%
    Finland and Western Russia 1.8%

    ^^I think all Dad's GB/I regions above are correct, just the percentages for some are over-inflated.

    My results at Living DNA were just slightly overestimated.

    98.7% United Kingdom
    1.3% Scandinavian

    According to my research about 4-5% from my Southeast England region should be pulled to German/Dutch. It will be interesting to see what the German update does but for now Living DNA was accurate for me. By the way they repeated this small "error" for my sisters, Mother and paternal aunt.
     
    Estimated ancestry after reviewing Ancestry.com, 23&Me, FTDNA My Origins, Living DNA and known family history:
    33% English, 27% Scottish, 18% Welsh, 18% Irish, 4% German/Netherlands
