I am seeking information regarding the following Hoffman family. The parents moved from Prussia to the US in about 1857 and lived in or near Columbus, Columbia County, Wisconsin at least through June 1880. I find no trace of them in the 1900 or 1910 census for Columbus. Any information or leads greatly appreciated.

Email addresses come and go. My permanent address is 410 West Park Place, Spokane, WA 99205.
