I am searching for the ancestors of my fourth great grandfather, Richard Thompson. He was born about 1766 and married Mary Moore in Halifax, VA on 03 March 1789. He and Mary departed VA for Grainger Co., TN about 1791, traveling with a group of her family including brothers Mackness and Rice Moore (children of James Moore, Sr. and Mary Rice). Mackness married Sarah Sally Thompson; also in Halifax in 1789, and she was probably the sister of Richard. William Thompson is a common name used over and over in generations of this family.
