I refer to the message called 'Final Hood List'.

Among the district names of the realm 'Island Realms' I find the two district names Baffin Island and Helluland.

I think it is important to note that Helluland is the Norse name for Baffin Island.

Helluland ('Land of Flat Stones') = Probably: Baffin Island.

Markland ('Forest land, border land') = Probably: Labrador.

Vinland (Plain land')= At least the northern part of Newfoundland.
