Thanks,

I've been through those online muster rolls but they are almost exclusively company information. There are very few references in them to brigadier generals or colonels commanding brigades. I was hoping to find the AdjGens records of brigadier appointments. The online info on the NARA site contains the Special Orders of the AdjGen of Texas 1862-1865 which contains much commanding officer info. Unfortunately it starts on 4 Jan 1862 so doesn't include any 1860-1861 info or records of appointments resulting from the 26 December 1861 reorganization.
