Your information is close, but not complete. Here is how I am related to those living in Fussville, WI. My direct ancestors are Peter Schneider who married Appolonia Schmitz, 28 May 1850 at St. Anthony's in Fussville, WI.
Appolonia Schmitz is a daughter of Mathias Schmitz (buried at St. Anthony's Cemetery, born 15 March 1806, died 17 Aug 1851). Her mother is Anna Marie Hoffman (buried at St. Anthony's Cemetery, born abt 1810, died 1 Jan 1874). She was 64 years old when she died.
More is coming. I am posting it on the Genweb board so all can benefit from my research. Personal responses welcome.
