Haha, I get notifications of all the modifications to the Norway "family" as a Norway tag follower. I never looked into it enough to see if it was a legit name or not. Calling people by their place of origin isn't new, but most of us have used them as nicknames, not proper names.
Edit to add: Oh yeah--I'd go with Kálf, too. The standard practice is to name them as they were named at the time.
