I don't see what Site you are referring to, The only site I can recall mentioning is, Ron Brothers, "Roster of the 10th Texas Cavalry" . And while It may not be totally complete, It is the best I have Seen.
A good Book on the 10th Texas is Chuck Carlocks Book entitled "History of The Tenth Texas Cavalry (Dismounted) Regiment 1861-1865" printed by Smithfield Press, P.O. Box 821653, N. Richland Hills, Texas 76182. Copright 2001.
