Thank you for your reply. I suspect Mary is probably buried somewhere in Putnam Co. along side her husband Richard C. Campbell. The married at the Cane Creek Baptist Church in Putnam Co., TN, and several of their children subsequently married McBrooms in the Baxter area.
There was also a John Carr, b. ca 1800 who married Rebecca Jones, b. 1803, dau of Prettyman Jones, of Buffalo Valley, Putnam Co., TN. I don't know of any others. Thanks for you efforts. Jack
