Interesting. I've also documented my mother's family coming primarily from the German/Swiss Alsace Palatinate but oddly have NO Central European DNA showing up. I have a mix of Finnish-Volga/Ural and Middle Eastern. Go figure. My grandfather did look very Middle Eastern and I've always suspected Jewish ancestry, but the Finnish-Volga/Ural I'm very interested in where that's coming from. I hope AncestryDNA does more research and narrows some of this down a bit.
