My grandfather was Jozef Zonak. His Mother's name was Ludwika/Leokadia Zonak Wyrostek. Her husband's name was Piotra Wyrostek. I am trying to find my grandfather's birth certificate. If anyone has any information on the Zonak family. I would very much appreciate your help. There is a rumor that my grandmother Ludwika was raped by a german soldier who's family she was taking care of. I was told he was the father of my grandfather but I have no backup to prove this. Any help would be appreciated.
