Can anyone tell me the name of the township that Cooper, OK was in? My gggrandfather, Joseph Stewart, lived there and according to a letter that I have that he had written to his son, he was elected Justice of the Peace of the township. The letter has Cooper, OK written at the top and he mentions a couple of his kids in Kingfisher. So I'm assuming tthis Cooper is the same Cooper that used to exist in Blaine County. Any help would be appreciated.
