Thanks for your help. That explains why Buttran isn't on the Georgia militia register. If this man was 1st Lieutenant of Randolph County Reserves, he's not in Confederate service, which explains why his name isn't on roll with any Confederate military organization.
The other officer name is William M. Lowe, Lieut. Col. of the so-called 13th Alabama Cavalry Regiment. As a resident of Hunstville, Lowe enlisted in Co. "I", 4th Alabama Regiment, received a wound at Manassas and a discharge on Dec. 9, 1861. By late 1863, he had begun to raise on irregular mounted command south of the Tennessee River, but was never authorized by the Secretary of War or any Confederate commander in Alabama. Lowe captured at Whitesburg AL, Mar. 11, 1865, he was released on oath at For Delaware, June 6, 1865, citing his command as the 13th Alabama Cavalry.
Lowe later became an Alabama Congressman who defeated Joe Wheeler in a contested election for the U.S. Senate, but was denied his seat during a lenthy recount lasting almost two years.
