Exact opposite of my test.
I have traced many lines back to England but I had 0% British, 84% Scandinavian with the rest Eastern or Southern Europe. All my matches have high 35%+ British Isles, some 97% or more, with only partial Scandinavian results. I am getting many matches with Central Europe, which I do not have. In fact, more than half of my matches have no background in common.
I figured my high Scandinavian results were due to Vikings in the British Isles, but with matches like I am seeing, I do wonder.
