I am interested in the Stampley family because John Stampley b. 1750 m. Martha Phoebe Curtis in South Carolina abt. 1775.My primary research is on my Curtis family but I have also taken an interest in the Stampley family.I have a George Stampley b. abt. 1740 who married Elizabeth ? abt. 1768.I show a daughter, Margaret, but she seems to be a different person.I show her date of birth abt. 1794 and show her married to Joseph M. Slater in 1827.I am unsure what the relationship is between John and George.Some think they are brothers, I think John is a nephew.One of the problems as your query illustrates is that there are many gaps in the historical records available to research the early Stampley family relationships.George had a brother, Henry Stampley, who was in the Natchez area in the 1770's.I believe Henry played a role in the Curtis party moving to the area in the early 1780's.One theory worth persuing is that your Margaret is a daughter of Henry and his wife Margaret.The first Baptist Church in Mississippi, Salem Baptist Church, was formed at Margert's home in 1792 after Henry died.
