Levonne, there were two branches of the older Gaddy/Gaddey family, one in Marion District of SC (Ithamar) and the other in Anson (Thomas, Ithamar's older brother). There are numerous Gaddy burials in the Deep Creek Baptist Church cemetery in southern Anson County, NC, a very short distance from a "white" church of the same name. The original Deep Creek (in which blacks and whites worshipped together)had moved from the Chesterfield area of SC in the early 1800s or thereabout. That makes me think your tie will be with these Gaddys, rather than the branch in the Marion area. I'd suggest you concentrate first on Anson County--the Historical Society, Genealogical Society, and the public library in Wadesboro, NC. See if anyone has run the census "slave schedules" or has a list of Deep Creek burials. Contact me directly by e-mail if you have difficulty locating addresses or the like. And happy hunting!
