The online info available from the Brunson and Faris/Phares genealogies my be helpful. Also, there are two books that may be helpful. Warren Skidmore wrote one and Jerry Alsup wrote the other. The history of Joseph Skidmore of Randolph Co VA (now WV) may be helpful also. It notes that some of his family left the area and wen into VA and NC. They spread out from there.
Happy hunting! My children's ancestors are listed in a online genealogy called My Eastern Ky Family (if I remembe correctly). They are descended from the Hamiltons of Boyd Co. KY.
