Requesting any information on Amiel F Polzin born Feb 9,1889 in Stettin, Germany. This information came from his WW1 registration card. He died Sept 8, 1944 in Minnesota. He married Winnifred "Winnie" McCartney born March 27, 1892 from Iowa. We are having difficulty finding information on the Polzin side. Any information would be greatly appreciated. Any hints on German geneology sites? Thank you, Mirja Mahonen
