I don't have any kingdoms named :| I just added the cities and countries. The kingdoms ARE separated by grey lines on the maps, but I didn't name them :| 

But the Storm Plains could be a kingdom, a proud, horse raising kingdom with a gnarly cavalry, close partners with the Kingdom to the north who also had a viscous cavalry, but their cavalry got turned feral. And the northern area of the plains is being taken by Ogual.

Or you could just pick a random place, name it and note which kingdom it is. Come up with a cool name and I'm down.
