Ephraim Wilson

My gggrandfather was Lorenzo Wilson. He joined the 8th Mississippi Infantry (True Confederates) at Raleigh, Mississippi. He was captured at the Battle of Chattanooga (Missionary Ridge) and was sent to the Federal prison camp at Rock Island, Illinois, where his died. His fathers name was possibly Ephraim Wilson, and moved to Mississippi from Georgia around 1800. My family has been unable to confirm this for years. Anyone with any information please contact me.
