Ludwig (Louis) Zinke (1817-1881) and his wife Friederike (1818-1899) are buried at Rienzi Cemetery, Town of Empire, Fond du Lac Co., WI. They lived in the City of Fond du Lac, where he was a grocer. Is someone interested in this couple and their descendants? I have scattered items of documentation that I would like to exchange, and would like to piece together the rest of the family including children and grandchildren.
