My G-Grandmother's name was Izula(r) Florrie Jane Adair Medlock. Her father was Robert Sidney Adair and Mother was Lucy Jane Price. She was his second wife. His first wife was daughter of a James Hood. They lived in the Gwinnett, Co. area during the time period you mentioned. I have copy's of pages from a book written about The History of Gwinnett County. Many of the Adairs are mentioned in the copy's of these pages taken from that book. I'm trying to find out who Robert Sidney Adairs parents were Looks like he could have also been Robert Sidney. Could be the one you mentioned. I also show that Robert Sidney and Jane Price were in Thomasville,Ga. in the 1860's. The book also mentions Judge Adair who it say's was in good health up until 1854. He died Sept. 1st and was buried at Fairview. It says his widow survived until July 23, 1869. I'm sure this is the same family you're researching. You can either post a followup on the board or e-mail me directly. Hope to hear back from you soon.
