Her name was Rosilla in the 1870 census, Rosa in 1880, and Rosline on marriage records.
At census time on 6/4/1900 Rosa, 42, was head of the house in N Okaw Twp. She had been married 24 years with 10 children but only 7 still survived. Living with her were: Allen E, 22, Rachel, 19, Cleveland, 15, Earnest L, 11, Olive M, 8, Clide S, 6, and Leon J, 4. Rosa was a farmer, Allen had no job. Neighbors were unfamiliar names. Where was Jerome?
Her birth date must be wrong as she was not part of the family in the 1860 census.
