Had I remembered, it would have been apparent that Valentine Cameron belonged to a Georgia company. Capt. James C. Thrasher's Co. "F", 38th Tennessee Regiment, organized in Gwinnett County GA. That may explain the "troop rally train" -- this man had plenty of company, so to speak. Cameron either lived there or in Jackson County GA.
