I am looking for information on the family of John NEISIUS and Mary ERNST. They were enumerated in the 1860, 1870, and 1880 censuses in Rubicon. In 1880, there was a man living with them named Jacob NEISUS, who was listed as grandfather (perhaps father to John instead). In the 1870 census, a Catherine ERNST lived with them, probably Mary's mother. Thanks. kathy
