In researching my Hefner line , and reading love letters written between my ggg-Grandparents Mary Lorenna Eib and James William Young during the time of the Civil War, there is mention of Marys cousin Jacob Eib from Harrison Co WV.
James and Mary Eib Young were the parents of two daughters , Hettie (who never married) and Carrie, who married my gg-Grandfather Lloyd Beryl Hefner May 27,1890.
Is this the Jacob Eib you're looking for ? If so, we have a connection. I don't know who Mary's Father and Mother were. Maybe we can share information.
