Results for Knott County KY are probably backwards

So, it's an agricultural processing county mostly?  What's up with that?

Presumably it used to be a mining area. There's a town in the county called Coalgate. Perhaps there was a Mr Coal, but it is, just about, on the main Oklahoma coalfield.

Coal County was, in fact, named neither for a Mr Coal nor for the coal to be found there, but for its pre-existing main settlement of Coalgate.
Which, however, is named for the coal to be found there.
