It took abit of searching but I finally encountered a descendant of one the original members of the community.He directed my attention to a magazine article of May 1983 in the "Looking Glass", a magazine then published monthly in Hatfield, Arkansas.
Essentially, the first "name" for the community was "Sulphur Springs", for the white sulphur water spring that keep so many alive in the early and meager years.Jim Blake was the first to establish a store and post office next to the springs and held it for a number of years.Mr Blake decided to move to Battiest, Oklahoma and sold his store to a Jim Winters.Mr Winters didn't want to hassle with a post office so a local Choctaw Indian named Larson Watson built a small building alongside the store, took over the post office, and changed the name of the community to Watson, Oklahoma.
The address for the magazine is as follows (it may still be publishing): The Looking Glass P.O. Box 240 Hatfield, AR 71945 (870) 389-6725
I will donate a copy of this article to the Idabel Library genealogy section for future study or review.
