If you have a look at that link there's a mention of King Eric the second allying Norway with France...
Here's some info about him: http://en.wikipedia.org/wiki/Eric_II_of_Norway and http://www.dokpro.uio.no/umk_eng/myntherr/em.html
I haven't found anything else indicating an alliance though so it might not even exist for all I know...
But I though it could perhaps be something we could look into a little further... In any case, the article is depressingly short in it's current state.
