    That's surprising. I thought that U106 is more numerous in Sweden.

    L238 is almost non-existed in England, so it's not "Pan-Germanic".

    Study shows Ancient Icelanders really had a mix of Celtic and Norse ancestry.

    "Abstract:
    Opportunities to directly study the founding of a human population and its subsequent evolutionary history are rare. Using genome sequence data from 27 ancient Icelanders, we demonstrate that they are a combination of Norse, Gaelic [Celtic], and admixed individuals. We further show that these ancient Icelanders are markedly more similar to their source populations in Scandinavia and the British-Irish Isles than to contemporary Icelanders, who have been shaped by 1100 years of extensive genetic drift. Finally, we report evidence of unequal contributions from the ancient founders to the contemporary Icelandic gene pool. These results provide detailed insights into the making of a human population that has proven extraordinarily useful for the discovery of genotype-phenotype associations."

    I think a study should be done on the Portuguese island of Madeira. It is known there is Sub-Saharan ancestry that was absorbed there from slavery (and likely migration from Cape Verde also) but I just found a GEDmatch result from there today and the person is around 1/8 Sub-Saharan. Up to now, I had seen results all throughout the single digits but none exceeding 10%. When you model their Sub-Saharan ancestry as Fulani they could be modeled as 20% Fulani, and the rest Iberian.

    All that has been determined by professional studies is that around 16% of the maternal lines are Sub-Saharan there, but I suspect there are parts of Madeira where the African input is higher than we might think.

    Sardinians being like Neolithic Anatolians is quite amazing.

    I think the other Islands are less unique and more like mainland Europeans.
