I just have a feeling your Sameul was the brother of my Phoebe Riggs Brindley.But about all I have that early is passed down stories, that she was born about 1769 in Tn, the Dau. of Dr, Asa Riggs. Phoebe and Frazier Brindley's first child was born in Jeff. Co Tn.in 1795. They moved to Franklin co GA ca 1800, then to Blount co Al in 1819. She had a bro. Clisby, but he does not seem to be the ones I find.Thier son was named Asa Riggs Brindley. I have records from Tn where Frazier and a SamuelRiggs were on land deeds. so they had to related.
