I'm trying to locate info on my daughter's paternal gggrandparents. Their names are supposed to be John Peter KOELLEN/KAELIN?/KOHLIN? & Mary RENK/RANK?/REINKE? They had a son George who married Florence BABCOCK of Richland Co, WI. He name his son after his father supposedly. Also, Mary RENK was supposed to have died from a fall/leap from a mental hospital window in Dane County about 1947/8. John died in 1953, not sure where.
