Gregg, this is a post I received from Patricia Adkins-Rochette on a book she wrote on Texas State State Troops. Maybe she can help you.

Please be advised that in my 1,022-page book, I have transcribed 240 militia listings of Texas State Troops with the accompanying militia brigade correspondence. ..Yes, I have all - i.e. I tried to include all - of the original records from the Texas Archives that addresses the then 34 counties of the seven militia brigades of North Texas. ..Also, I'm the first to transcribe all of the seven militia brigades' correspondence, which has a surprising amount of Indian Territory history.
