Claudette, My husband has Erdmann's on his side of the family. What type of information are you looking for? If interested, I may be able to help you with current generations. I don't know how much help I can be on the ancestors, but may be able to find some info through a family member married to one of the Erdmann's who is head of genealogy here in the local library. She has done alot of research. Good luck! Denise
