This was one of several replies I meant to make once the NPS index was working again. I'm still not sure what they did to improve the service while it was down.
Joseph W. Evans has a service file with Co. "A", 34th Texas Cavalry Regiment. Anyone interested in copies can order through a message board service created to fill this need. The link appears at the top of this page. Scroll back there and enter information about the soldier and his unit.
