I'm looking for info on Henri Ritzschke and his wife Christinia. They came to america 1869 and settled in Oshkosh, WI. They had 6 kids. Carl b 1842, Henry b 1850, Frederick b 1849, Herman b 1839, Anthony b 1852, Frank b 1855 (all in Germany). I know they spelled their name like this when they came to the us, but a few changed it upon arriving in WI.
