My Ancestry results conflict a bit with my known (and researched) family tree.
My paternal grandfather's line is exclusively Irish and English. My paternal grandmother's line is Irish (her father) and Finnish (her father). But I score low for "Great Britain" and 15% "Scandinavia", but I have no known Scandinavian routes on either side. I'm not sure what to make of that. Viking rapebabies, maybe?
Similarly, my maternal grandfather's line is mostly Dutch, with one set of great-great grandparents who immigrated in 1907 from the Russian partition of Poland (I don't know precisely which modern day country they would have hailed from). I guess this could explain the high score for "Eastern Europe", but 26% seems a bit high for that one set of ancestors. I guess it's plausible due to DNA recombination.
My maternal grandmother's line is German and Italian (my great grandfather was from Osnabrück, as we're several generations before him) and my great grandmother was from Molfetta (as were several generations before her).
Yet, I don't really score high for Europe West, so perhaps that's also where those Scandinavian markers came from as well.
I popped the raw data into GEDMatch too and tried a few calculators, but they didn't give me much variation from what Ancestry reported.
I'd be interested in any input, but you can save the "hurr durr you paid the joooooos to store your DNA!" bullshit.
