I'm looking for any leads to the parents of Mary and Nicholas Wisneske/Wisniewski. The parents are John and Frances who came from Poland to WI around 1871-1873. I have Mary Wisneski Senoracke's obit and Nicholas Wisniewski's obit and it talks about a sister/half-sister Catherine Sczezinski/Sczeczynski who married Peter Cherek. Thanks in advance for any help.
