George,

Sorry, George but I just don't have anything much on State Troops....this is from the Soldiers and Sailors System.
By the way, this is the only Cleveland (out of 38 in the system) that was a Major.

L. G. Cleveland (First_Last)
Regiment Name White's Co. D., 1 State Troops, Texas Infantry
Side Confederate
Company D
Soldier's Rank_In Captain
Soldier's Rank_Out Major
Alternate Name
Notes
Film Number M227 roll 7

Check this out! Can this be Captain Sheppard????? Same outfit. I did a search in the above unit to see if Sheppard was there and got this hit. What do you think?

J. B. Shepherd (First_Last)
Regiment Name 1 Regt. Texas State Troops
Side Confederate
Company C
Soldier's Rank_In ?
Soldier's Rank_Out ?
Alternate Name
Notes
Film Number M227 roll 33

George, I wish I could be of more help but that is all I have for now.

Thanks,
Gary
