Port Gellhorn is the only region named after a person and I have thoughts about it

Vice City, the Keys, Grassrivers, Ambrosia, Mount Kalaga. Five names that describe a thing or sound like a place.

Gellhorn is a surname. Real American towns are named after people constantly, usually whoever owned the land or built the railway, and those names outlive any memory of the person. That is precisely the atmosphere the region description is going for: cheap motels, shut down attractions, a place that used to be for something.

A forgotten coast named after a forgotten person is the most economical piece of world building in the entire six region list, and it is doing that work before you have seen a single frame of it.
