Where did 23andMe put you on the Global Similarity Map?
oh, nvm, here:

It has you as a Norwegian more than anything but not outside the English zone either. It put me as very Irish so this is another thing I don't take very seriously :D
I'm of English, German, Norwegian, and Dutch ancestry, and on K15 you score higher Baltic and Atlantic with lower North Sea than myself. I think that makes sense with the Swedish and Irish you have.
On that plot, you're close to where I'm at if just aa slightly lower.
