Sorry it has taken so long to answer.
I have the following (on computer without looking for the papers): Edwin Mozley b. 1764 Va. d. 1820 Ga. married Sarah Gathright same date you have, b. 1775 d. 1831, I show one son; John Edwin Mozley b. 1-25-1798 Ga. d. 11-13-1867 Fl. married Martha Hicks Morgan.
I will look for my other papers to see what else I can find.
My relationship will be thru Sarah, I will be a half 3rd great-grandnephew.
Let me know if this helps....
