Looking for Christian's port of entry (or place of origin in Germany). We believe that he arrived around 1889 with wife Anna, and children, John, August, and Sophia to Chicago area. John married Katharine Koch-- Sophia married Katherine's brother, George Koch. John and Katharine moved to Michigan (and eventually so did Christian and Anna). August went to San Franscisco area and married. Sophia and George stayed in Chicago... as did their descendents for four generations. All paperwork that I have located has been consistent on the spelling of the last name.
