My gggmother is Isabella DUNNAVANT b1861 in Giles TN. I believe her gggparents were Joel DUNNAVANT and Carey BURTON(d of Abel BURTON and Ann COUSINS). I found this information in the Giles County Courthouse, but it was a typewritten outline with no real references or indication of the submitter. There is information going back another 8-10 generations on Carey BURTON's side, but very little on the DUNNAVANT side. I would appreciate hearing from someone who could shed some light, especially on the link between Joel and Isabella.
