Where to put your Saxons?

[Arturus Uriconium]

I think the Irish, or I should say Hibernian, question is overlooked a lot with the Anglo-Saxon interest taking centre stage somewhat. I wonder, and some scholars have argued, that, just as the Saxons were used in the east, certain Hibernian groups were used in the west; such as the Desi and Laigin. If, as it is thought, the Lleyn Peninsular is named after the Laigin from what is now Leinster, you're not going to do that if they're the enemy, and you still find 'Gwyddel' place names in the area.

I wondered if Bailrigg was named after Hiberno-Vikings? I went a searching on Google, but couldn't find anything.
