I never really thought about the surname being English, but you're right, I like the idea of it bridging the gap.
Anyways, I'm kinda going back and forth between
Wilhelm and
Klaus, as
Wilhelm sticks with the original "theme" I was going for (German/Swedish forms of "traditional" English names --
Anna and
William respectively) and I love the association with the brothers Grimm but at the same time doesn't fit the character as well nor do the nicknames for it.
And
Klaus fits better but doesn't really go with the theme (but it's familiar enough so it'd be okay) plus there are already a lot of
Klaus's in fiction...
Idk, sorry for rambling and thanks for the input. I definitely think I'll go with
Klaus Alexander if I stick with
Klaus. :)
