My Grandfather is Gilbert Kania (1924-1979). He lived in IL and WI. He was married once before my Grandmother Audrey, to his first cousin. They had a child named Gilbert Martin Kania Jr. Eventually Gilbert and his cousin divorced. She remarried and the son took the new husbands last name. I believe he is now Gilbert Martin Darcy. Gilbert was married to a woman named Geraldine and living in IL when he passed away. I can't locate her either. Any information would be helpful. I believe Geraldine to be born around 1944. Her maiden name is Zimmerman and she was remarried after my Grandfathers death.
