Thanks for the link, Noaide. It's very interesting.
In the Table 1 it is particularly intersting to note that the frequency of I1a is 46.55% in the Finnish speaking Southern Ostrobothnia (SO) but only 36% in the Swedish speaking Ostrobothnia (SSO). I think this suggests that I1a arrived in Finland before the mass migrations of Swedes in the 13th or 14th century. I think those latecomers had relatively much of R1b unlike earlier Scandinavian immigrants. The highest frequency of I1a seems to be in Satakunta (52.08%) that is now almost totally Finnish speaking.
