I don't remember if I contacted you about this or not. There is a bio of Louis Schumm Sr. on pages 764-765 and his picture in the 1904 book History & Bios of La Porte County, IN by Rev. E. D. Daniels. It mentions a wife Mina (Domke) and two children Louis & Rosa. Nothing about the Bauchs. Perhaps Mina (Minnie) remarried after Louis died.
