looking for information on Wiedemeyer family from Westfalen area who relocated to Carroll, Iowa approx. 1864. Anton Wiedemeyer in particular, relocated to SFO and became known as John Whitman. Was a family of about 8 children. Believe that there was a son's wife whose married name was Agnes Wiedemeyer. Had lost contact with her. Now deceased. One daughter married a Kanne, also from Carroll. Information please.
