Sorry. Going through old posts and found this message. My Grandfather Anton Joseph Zahn immigrated to Napoleon, ND from Prussia. His first wife died and I know one of his children was Elizabeth Zahn married to a Glatt in later life. After his first wife died he married my Grandmother Brigitta Fettig who had immigrated from Odessa, Russia. Her married name was Schwan and she was a widow with three children. Ben, Eva and Agatha. Don't know if this will help.
