Benjamin Bodhránaí - could your Norse area be the North of Scotland, "Sutherland" (because it was south of Scandinavia, Sheltland and Orkneys)?
Bev, Alba like Albian was a name for Britain, the fair land (because of the white cliffs of Dover??) I've asked quite a few people how the name came to mean only Scotland, but none of them had an answer.
Scotland is the land of the Scotti, the Irish, Normandy, France the land of the Northmen (Vikings), Russia a settlement of Scandinavians, and so-on; our nations are very mixed up
