I know of at least three Camp McCullough's in Texas. Smith County, Mclennan County and Bexar County. The one your looking for is near Georgetown Texas. Gurley's men were at this one.

CONFEDERATE TEXAS TROOPS
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.
I did not see a Texas pension for Benjamin E. Bishop or his wife.
