Most pension applications I have seen have one or two comrades who authenticate his service. Are there any on the papers you hold. This could aid in identifying his unit.

Below is information on your man in the 30th Texas.

30th Regiment, Texas Cavalry (Gurley's) (1st Texas Partisan Rangers)
30th Cavalry Regiment [also called 1st Texas Partisan Rangers] was organized at Waco, Texas, during the summer of 1862. It was formed with about 800 from Waco and Round Rock, and Hill Country. Assigned to D.H. Cooper's, Gano's, and Parsons' Brigade, Trans-Mississippi Department, it fought in Arkansas and later in the Indian Territory. The unit reported 16 casualties at Poison Spring and 19 at Cabin Creek. During May, 1865, it disbanded at Austin, Texas. Colonel Edward J. Gurley, Lieutenant Colonel Nicholas W. Battle, and Major John H. Davenport were in command.

His record in the Compiled Service Records yields only:
