This is getting wierd. I have a James T. Snead in my records, born c. 1832 in Patrick Co., VA. He was the son of Samuel & Esther Snead (don't know Esther's maiden name). He was married to Mary V. Meador. They lived in Princeton, Mercer Co. at the time of the 1860 Census. Then he disappears from records. I assumed that he died, but he may be your James T. Snead. I have not been able to connect him to John T. Snead, but they may be brothers. I notice in the postings that someone seems to have information on the Snead/Meador connection. James T's son William Moody Snead also married a Meador.
