I really don't know. My gggrandmother was Sithey Darby, b.1812 Ohio, to Samuel Darby and Charity Redyard. She married Henry Fry in 1830, Jackson Co. I have found a lot of Darby's. Haven't found an Addie but she may be a cousin and i haven't researched that yet. Sithey was a twin to Britain Darby. Don't you love these names - Addie, Sithey, Britain? If I can be of further help please write again, although I wasn't much help here. So glad to hear from you. Coralie Minner Schepansky
