My grandmother, Dora(Dworje) Ferber was born in 1891 in Austria. She immigrated to the US in 1906. Her parents were Zvi Elimelach(Harry) Ferber and Esther Rivka(Rebecca) Feuerrman. I have one indication that my grandmother may have been from Krystynopol, but have not been able to find any records. I would like to find any siblings she might have had, as well as ancestors. Thanks.
