The Nords really have their own naming thing...
While I mostly agree with you, some of the Nord names are close to Scandinavian and European names. A few examples:
Agnete the Pickled -I know a few Swedish females named Agneta
Else God-Hater - Elsa is not uncommon in Sweden
Hans Black-Nail - Neither Hans is uncommon
Jesper - Ive had scoolmates named Jesper
And the above mentioned are only some of those Ive encountered in RL. And the way of being named Black-Nail, God-Hater etc is not unlike names some Vikings used. For instance http://en.wikipedia.org/wiki/Erik_the_Red. But, as said, Nords are inspired by, not based on Vikings.
