TCWeeder, I wish to thank you heartly for adding a major piece to the Silesia interim migration record of Germany, to Silesia and then the Volga. Frank Jacobs, a male “paternal” descendant of my ”maternal” parent’s family, using Y DNA to track my mother’s family. (Y DNA was required from a male member of the Klaus family as male Y DNA from my Jacobs family would not touch her family record. Of course the written history (thank you) fleshed out the story.)
