    British & Irish 23andMe results

    As I mentioned on another thread, I am an American of overwhelmingly British and Irish descent (with very little else that I can find; I am only aware of one French and one Swiss ancestor). I am perhaps most interested in determining what extant global populations I am closest to. Various Eurogenes tests on GEDmatch have been the most revealing thus far, placing me very close (somewhere in between?) Irish and Southwest English, comparing my results to the reference panels and using the Oracle results.

    I have seen some 23andMe results from a few present-day Britons and Irish on here, and they are strikingly close to my results. But I would be interested in seeing more, so if any posters would be willing to share, I'd be very grateful. (Either here or as a 23andMe share would be great.) Best wishes to all!

    As I have no known British or Irish ancestry, I'm not really part of your primary target group - but it might be interesting to know I show 9.9% of it, a pretty significant amount, even though known family history is just about all Swedish. Apparently something like 4-10% B&I is very common in Scandinavians.

    Some other mainland European groups show even more - I've seen Dutch users with no known Isles background but something like 24% B&I in Ancestry Composition. Many figure it's down to 23andMe having way more people in their database with a British/Irish background compared to other European backgrounds, so some DNA that's generically Northern European currently gets categorised as B&I.

    Anyway, here's my AC:

    99.9% European

    Northern European
    62.2% Scandinavian
    9.9% British & Irish
    2.3% French & German
    0.5% Finnish

    I have heard of some full blooded French people scoring around 30% or so in the British and Irish category at 23andme on the Ancestry Compisition test.

    Sure, here's my 23andMe results in Speculative. My known ancestry is predominantly British and Irish, with some French and German. It's possible my French and German should be higher.

    Thanks to all who have replied! FWIW, below are my results in speculative mode. They are fairly close to Stephen1986 and his brother, though with a bit more of an Iberian/Broadly Southern European contribution. I have no knowledge of any direct ancestors from Iberia/Southern Europe, and I tend to think these numbers reflect Iberian heritage in my "celtic" ancestors.

    My father was RC, born 1913 in County Tipperary Ireland as were all of his ancestors back to the late 1700s and probably a lot earlier. My mother was Protestant born 1920 in London England and all her ancestors I have found were from London or near by counties in southern England.

    My 23&me results in Speculative Mode were as follows:

    99.8% European
    0.2% Unassigned

    99.4% Northern European
    82.0% British & Irish
    3.9% French & German
    0.6% Scandinavian
    12.9% Nonspecific Northern European

    0.4% Nonspecific European
    0.0% for all other 23&me populations

    Does anyone know if 23andMe's "British & Irish" might represent the more "Celtic" (i.e. pre-Norman/Viking/Anglo-Saxon) ancestry of the Isles? And that those with greater admix of Germanic inheritance have on average lower percentages of "British & Irish" by 23andMe's qualifications (and more Broadly Northern European, Scandinavian, etc.)?

    I think that's probably the case to some extent, but it's pretty difficult to tell Germanic from Celtic by DNA. The "Celtification" of Britain was to a great extent cultural assimilation of pre-existing populations rather than a genetic population turnover. Obviously there was some admixture, but the waters are muddied by the Celtic presence in central and western Europe, making many modern mainland groups look similarly admixed. Some of the Germanic populations that flowed in later had probably already had some opportunity to admix with Celts before they left present Denmark or northern Germany.

    Britain and Ireland tend to cluster very close to the rest of northern Europe in PCA (like 23andMe's Global Similarity Map) and often have considerable overlap. In the Global Similarity Map the English basically occupy the same space as the Norwegians, whose cluster I'm plotted in the middle of. The Irish are a little more apart, but that seems to vary a lot from study to study.
