My brother has done a lot of research, but I have just started. Did the Ancestry DNA and was very surprised. We were told a lot of Irish on both sides and that came out 52%, also told some Scottish and (Great Britain) that was 13%, we were told possibly French, American Indian, German, Scandinavian etc, so I thought we were about half Irish and little bits of a bunch of other stuff, well came up with 30% European Jewish, along with a couple trace amounts, Scandinavian being the only one included on our list at 1%.
DH also did his and expected mostly French and German, got mostly Iberian Peninsula, and Scandinavian.
