The link you sent doesn't seem to work. I couldn't find any information that this Susan (Joynes) Conley was related to a Henry Guyan on genealogy websites. Her mother was Mary "Sarah" Caudill. Her Caudill brothers supposedly fought against those evil British (sorry Canadians) at Kings Mountain and Eutaw Springs during the American Revolution. Mary "Sarah" Caudill's husband, Thomas Joynes, fought along side her brothers. One Caudill brother died at the Battle of Eutaw Springs.
Also, many sites like Wikipedia don't link the name the Guyandotte River to Henry Guyan. I believe the Susan Conley's story must be true as told to William Elsey Connelley. Henry Guyan may have been a great uncle to Susan?
Susan Conley's father-in-law, Captain Henry Connolly, commanded 200 troops against the British in the Revolutionary War. From his pension application made in the 1830s, he was at the Battle of Cowpens. His father, Thomas, was badly injured at the Battle of Kings Mountain.
