I dunno. The Greenlands? The Trentlands? Remember the kind of names that currently exist. The North is a kingdom, The Westerlands, The Crownlands, The Stormlands, The Iron Islands..these all go straight to the point with their names. The Vale, Dorne and the Reach less so but it's still nothing special. They're just named after the culture of the inhabitants. So don't go all out with something elvish or something as it doesn't fit in with the world at all.
