Frank, unsure if this will help or not, but my great-great grandmother was Elizabeth Menke Deiters Bendlage b. 1830 in Hanover, Germany. Not sure of when she came to the U.S. but know she married John Bernhard Bendlage on 7Oct1849 in Il. or Ia. most probably. Elizabeth had a sister, Adeline, who married a Groene. Adeline lived at West Point, IA and Elizabeth lived in the Washington Township, Lee Co., IA area (Wever to Fort Madison) after her marriage to John. The Bendlage's came up the river after immigrating to New Orleans, first settling in the St.Louis and Clarksville, MO area before moving onto the Fort Madison area.
