I believe that if you'll check more closely, you'll find that the James Abernathy who conveyed the tract of land to Nathan Abernathy was the 2nd son of Elizabeth Cox, widow of the James Abernethy who died in 1785. James Abernathy bought the Bissell, Rumfelt and Farrar places in one tract from Moses Bonner and his wife Charity in 1778, Book 17, p.21. John Rockett's wife (Sarah Abernathy) was given the Farrar place and the Bissell and Rumfelt portions went to elder brother David Abernathy and his wife Patty or Martha. Youngest brother (George) sold land along with his widow'd mother to one of the Rocketts in 1799 and later received other lands from his brother James. David Abernathy (died shortly after signing his will on 18 Jun 1795 in Lincoln County) was therefore a son of James Abernathy & Elizabeth Cox while Patty "the Widow Bissel" was a daughter of David Abernathy Sr whose will was signed 24 Aug 1808, after the 24 Jul 1804 will of Jacob Forney Sr which proved that his son-in-law David Abernathy (Jr) and daughter Christina (Forney) Abernathy were still alive at that time, as was Patty Abernathy aka "the Widow Bissel". I am as yet unable to explain who the Nathan Abernathy (who briefly owned the Hebron Baptist church property) was related to the James who died in 1785.
