Duane,
R.S. Lyles was from Rusk Co., and is on the Rusk Co., Indigents list as R.S. Lisle.
He was originally from Van Zandt Co., so he went to Van Zandt Co. to enlist.
I have a Photo of Him and the Pocket Bible he carried into the Civil War.

Have you researched the T.M. Leech of the 1st Regiment, Texas Cavalry,
State Troops, 1863-1864. I saw him on the Civil War System Soldiers and Sailors List.
It says his alternate Name was T.M. Leach; Or do you think he is the same as T.M. Leach in
the 10th Texas Cav?
