Hensci Terry,
I forwarded a copy of your post to a 'prominent Choctaw friend' in the Washington DC area, this guy has been practicing Indian Law for 40 years and have never come across such documents (I really don't think he was looking). Terry, I encourage you to publish this information as soon as possible. He was flabbergasted, astounded at your posted information. He said this is not taught in NDN law schools when studying the 5CTs and Dawes Commission.
Publish more soon, please and thankyou for doing so...
Eli
