Jacob was my maternal great-grandfather on my grandmother's side. I believe he was born in Czecholovakia--or at least his family was from there. He was married to Katherine (Katie). He had two daughters Mary and Helen and several sons: Jacob, Joe, and John. (I think that's all) He lived in Pennsylvania for awhile at least until my grandmother was a young child (she was born in 1909)I would love to find out any information about family. Where they were from in Europe. . .do I have any cousins out there, etc. I don't even know his birthdate, etc.
