Marilyn, I am sure by now that you have resolved the question of the birthdate of Sarah Jane Isaacs. But just in case.... this is what I have on her. In 1880 Jackson County Ky Census she is listed as a 5 yr old child....that would make her born 1874 or 1875. Yes she is the child of Linville Isaacs and his second wife Elizabeth Azbill/Azbel. Sarah Jane did marry a Becknell. I am descended from Linville Isaacs and his first wife Elizabeth Hisel. I hope this helps. Sincerely, Debbie Wilson Fehr
