Name for Poitou that isn't Aquitaine?

by Thornwell

I am creating a Kingdom as part of an Alternate History. The bounds of this Kingdom are linked here. I am thinking of calling it the Kingdom of Gascony & ______, but I do not know if that would correct. I do not want to call it Aquitaine. The Kingdom goes from the River Loire to the Pyrenees. It does not include Toulouse. It is basically the Duchy of Gascony, the western part of the Duchy of Aquitaine, and then Poitou, but I don't know what a proper name for this place would be. Any suggestions and/or historical perspectives would be awesome!

I'm a medieval historian of this geographic area, as part of the larger Occitan world.

Aquitaine is the modern form of the region's name which dates back to Roman records, from the same time as Roman name Vasconia (now Gascony/Basque). The earlier medieval form of Aquitaine was Guiana (in local old Occitan, or Guyenne in old French).

Like Poitou, all other names indicate Aquitaine sub-regions such as Dordogne, Agenais, Perigord.

In what period does your alternate history shift from real history?
