My great grantmother, Anna STARK was born in Fort Atkinson, Jefferson county, WI in 1868. Her father was August STARK and the 1870 census indicates that her mother's name was Albertine. Albertine E. FEHRMANN was born approx 1838 in Prussen and married August STARK Dec 30th 1867 in Jefferson WI. Albertine's parents are listed as Friederick and Frederike FEHRMANN. It sounds like Caroline could very well be Albertine's sister.
