Hi, Alan. As per your advice last year I am going to NARA to look through UNFILED PAPERS for my Pennington in Terry's Regiment of Texas Cavalry. This summer we have been to the Archives in Texas and found a little information. They did give me a good source that I don't know if others know of: Texas Heritage Museum, located at Hill College, Hillsboro, TX. They have a research center for Civil War. They did help me with a little information on Terry's Regiment, though very little is known.
