    Is Welsh a proxy for English or Native Irish?

    Upon receiving my mums results, I noticed a surprising 4% Welsh. Having looked through most of my matches I have noticed that several, including a few of my cousins have scored Welsh.

    Iím not sure if I should take this seriously. Is this a proxy for English ancestry?

    Welsh people donít and havenít migrated to Northern Ireland in the past so I am struggling to see where Welsh ancestry wouldíve come from in my matches.

    I don't know. I got 9% Welsh with a range of 0-23%.

    My y-chromosome line is Welsh, and I have a number of Welsh surnames in my pedigree. Overall, however, I got 66% Scotland, with a range of 50-69%. That makes sense, too, though, because I have a boatload of Scots surnames in my pedigree on both sides.

    I've noticed something similar with respect to my English matches, were a number of individuals, with no recent Welsh ancestry, are scoring in the 4-8% range. However, a similar argument could be made for Irish percentages and with the recent considerably higher than expected Scotland percentages, in the English population. Either the algorithm is catching 'real' shared components, that reflects a shared genetic history, or it's selecting a 'best fit' for that section of an individuals' genome. Remember the reference population genomes do not cover the full gamut of genetic variability found within a population, and this corner of NW Europe is more genetically similar than it is different

    I wouldn't take much notice of a region of just 4% in your results unless it is known in your heritage already. I get 9% Scotland but I doubt that I have any recent Scottish ancestor. I would think that it would be more likely where I'm from to have a more recent English ancestor than a Scottish one.

    My Welsh is likely high, and in my case it's likely to be English, but that doesn't mean it couldn't also represent Irish in a different person.
