Rebecca, My gggrandfather was Micajah Smith and his wife was Elizabeth Duty. They were both from Chatham Co., NC. I think that this Elizabeth was the daughter of Thomas Duty and Martha Brantley. I base this on the fact that the Colby Smith family and a Brantley family of Chatham Co., NC came to Georgia together about 1798. The Brantley family reportedly was that of Joseph Brantley of Chatham Co., NC. I think Elizabeth and her sister, Caroline came to Georgia with their Brantley relatives, not with their father. The Brantleys and the Smiths were close neighbors in Washington Co., GA . I wish I could offer you documentation but I cannot, so you will have to think of this as logical speculation!! Better luck with some one else!!
