The Norwegian version sounds like the "r" is rolled like it is in a lot  of dialects. But the English dialect doesn't roll the "r".
Not all that close, but my Norwegian last name is Knutson, and it is pronounced ka-noot-son with emphasis on noot. Anyway, I don't believe Krag was pronounced Craig until us Americans got a hold of it and pronounce it the way it looks to us and is more natural in our language. Ole Krag still had to be proud of us Americans adopting his and Jorgensen's design, no matter how we pronounced his last name.
