Earnest, I did a lot of work relative to the history of the 31st basically to Know the history of Lt Joseph Tivey one of the founders of Kerrville. The rosters exist both here at this web site and at Footnote.com. Should be relative easy to get the individual soldier records for both. I will send you the history that I worked up, plus other notes, if my wife gives me a chance. I will need your e-mail. I will look at Footnote. They coppied all the soldier records from the National Archives and have them on line. You can also apply for a copy from this web site for a fee, which goes to support several history sites like this.
