Mary Long, b. est. 1760, married John Owens of Laurens District, S.C. "Died probably 1823 [A broken tombstone in Duncan’s Creek Cemetery next to her son, Thomas Owens, states Ma?? Owens, d. 1823, and that is surely her]".
I have now identified the above broken tombstone;it is not that of Mary Long Owens (who would have been ADAIR at the time of her death).It belongs to her granddaughter, Mary Long Owens, b. Nov. 28, 1818 (twin). d. Aug. 1823.Mary Long Owens was the child of Thomas Owens and Ailcey Duckett.
I still do not know when Mary Long (Owens) Adair died.
