My husbands grandfather was Gustav Heidemann. Born Sep 15, 1874 and died 24 Apr 1952 in Freeborn County, Minnesota. He was the son of Michael and Louise (Zabel) (Schmidt) Heidemann. She had children by her first marriage.Louise died April 28, 1928 possibly Stargarrd, Germany. Her husband died June 22 1902.These dates were written in a family bible.Anyone have any connection to any of these ancestors?
