Jackie and Jim:
Saw Jackie's post that she had tracked her great-grandfather to S.C. and that the trail there runs cold. I encourage you to contact the Old Edgefield District Genealogical Society, Court Square, P. O. Box 546, Edgefield, S.C. 29824. The telephone is (803) 637-4010. I recognized the Vann family name as being one of the old names of Edgefield District; descendants live there yet.
OEDGS maintains an excellent genealogical library. When I checked their site to get the web-address, I noted that the Society does maintain at least one verticle file on the Vann family. The full-time director of the Society is Tonya Browder; library hours are 9-4 Monday through Friday. The web-address is:
I commend the library as an excellent genealogical resource. The Old Edgefield District Genealogical Society is the largest genealogical society chapter in South Carolina.
