Found this whilst trying to figure out what three members of a Scottish family I'm researching were doing in Poland in the mid 17th C.http://www.scotland.org/about/history-tradition-and-roots/features/culture/1576.html
One of the links at the bottom of the page is an article claiming there were about 30,000 Scots living in Poland in 1621?
Of course I'm not trying to suggest that Polish L21s are therefore of Scottish ancestry, but I suppose at least some of them could be.
So far no R-L21*s of Polish descent who look likely to be the progeny of Scots have shown up. Our only members with Polish ancestry belong to the distinctive Baltic Ashkenazi cluster, and that has not shown up in Scotland yet.
If the figures quoted are only half accurate though I expect some will turn up.
I have to wonder what the draw was, the people I was interested in weren’t even living near the coast, Bartons as it happens.
Yes that Ashkenazi cluster you found is very interesting isn't it, one of them would be a good candidate for the WTY project.
