James N. Sorrells was probably James Nathaniel Sorrells, b. 1807, d. 1882 in Walton County, GA.He married Lucy Ann Haynes.He is believed to be a brother to Sarah "Sally" Sorrells who married Whitmill Harrington Adair.In my database Sally is the second of at least 12 children born to William Alexander Sorrells and Dorcas Sanders.
The James Sanders you mention was possibly an uncle, perhaps a great-uncle, to Sally.Her grandfather was James Sanders but I doubt that he was the James Sanders you mention.
John B. Adair could be an uncle -- John Bluett Adair, son of Bozeman.I think there was a John Bone Adair around there somewhere at the time, too -- probably a nephew to Whitmill.
I am descended from Sarah "Sally" Sorrells and Whitmill Harrington Adair through their daughter, Jane, who married John L. Brooks in Paulding County in 1841.
