I have found online an extensive resource of the Treat Family from John Trott in the 1400s to modern day. From about generation 11 to the bottom of the document are concentrated in Searcy Co., Arkansas and Oklahoma.
NB: My Treat family connection deviates from the author of the document's line in the 12th generation, as I am descended from Stephen Treat and Sarah Reece through Richard Treat (Wright Co., MO, b. 1838) and not Jackson Andrew Treat, who remained in Searcy Co., Arkansas. Being as it may, I thought the document's relevance would be more apropos to you than me.
