I am trying to research my mother's family. Her mother was Emma Titz, born in Peterkow, Russia and her father was Edward Riemer, born in Zagrov, Poland. They were married in a Lutheran church at Douglas, North Dakota in 1908. The families migrated from Usteen Colony, Poland; Passen er Territory, Poland and Jitomuv, Volhynia. I am looking for any available infromation.
