Howdy, Robert !
Compiled Service Records of Confederate Soldiers Who Served in Organizations From the State of Texas. These microfilm rolls can be found in some of the larger Texas public Libraries and in some National Archives regional facilities.
You`ll find the men in this unit on this roll:
M323 - 192 Crump's Cavalry (Lane's Cavalry, 1st Partisan Rangers)
For swift service, I recommend you get his service records from here:- http://history-sites.com/research/index.html
Hope this helps,
