I'm trying to obtain information about my GG Grandmother Reva Oster (AKA Rebecca Oster). She was born in 1869 in Russia (I don't know where in Russia) and died in Louisville, KY in 1921. According to her death certificate her parents were Anton Oster and Hanna Finkelstien. I believe that she came to America with her family around 1880, and that she had at least two sisters. In the early 1890s she married Jacob Jacobson and they had seven children. Any leads would be wonderful!!
