Haha true. And AFAIK, pretty much everyone in Éire/Airlann has a bit of Viking in them, those buggers were very happy to mix it with the locals.
Which, funnily enough, kinda mirrors how the Irish diaspora tended to interact with indigenous cultures they encountered. They were far more likely to get along with and settle down with locals than the English, who looked down on at that sort of thing.
A friend's Great-Great-Great-Grandad was one such, came out to NZ as a sealer, fell in love with a local wahine, ended up living on an island the local chief had designated for Europeans married to Māori. [0]
And a Māori tribe in the North Island is known for the tendency for the occasional child to be born red headed / blue eyed, thanks again to open-minded local ladies, and open-minded visiting Irishmen.
I just like occasionally being technically correct on the Internet, the worst kind of correct.
