Hi. My Kaufmann's immigrated from Grindelwald, Switzerland around 1870 through Ohio to Indiana. My immigrants were Johannes "John" KAUFMAN/KAUFMANN Sr. (1819-1884), his wife Magdalena NUSBAUM (1829-1901) and their kids, including my gg-grandfather Peter (1860-1932). John's father was Christian KAUFMANN Jr. born around 1790 in Grindelwald and his mother was Magdalena KAUFMANN (not sure if that's her maiden name or not) (1789-1852). Christian Sr. (1758-?) married Anna ZIMMERMANN. If this sounds like it could be your family also, I would love to trade info. I have my direct line going back to the early 1500's, but not much else.
