I am looking for information on the Schnepf family. I have very very little, but am hoping someone else is familiar with this very rare name.

My GGG grandmother was Mary Fedelia SCHNEPF. She was born in Baden in 1827. She married Frederick KEINER (born 1822 in Cabling Rein) on 29 Sep 1853 in Watertown, Jefferson County, Wisconsin, USA. Mary passed away in 1871.

I have nothing on siblings let alone her parents. Would appreciate any leads. Thank you.
