Thanks for the reply.
William A. Cox joined the infantry when he was seventeen. His brother Cornealus L. Cox joined the Cavalry with Hilliard's Legion the next year when he was seventeen. That unit was merged to form the 10th Confederate Cavalry. He rode with that outfit till the end of the war and was paroled with Johnson's Army in North Carolina.
Cornealus returned home got married and had about 12 kids. He is buried at Pleasant Grove Congregational Church in Chambers County. He has no inscription on his grave of any Civil War Service.
Our family oral history has William killed late in the war in Virginia. Again thanks for the reply.
