Just searching & found your post -- OMG 13 yrs ago! If you're still looking for descendants of Hardiman and Permelia's children, my line is from their son, Washington George b. 1839, and I have info on that line. Let me know. Also, my brick wall is finding parents of Hardiman; have you been successful in that regard? Found a cousin in Atlanta that has xlnt documentation of Hardiman and Permelia's children and has been published to the web. If you're interested, will point you in the right direction.
Thanks, Suzanne Bennett Mejica
