Note: This post was reprinted in full with permission by Phil Edwards. The map is public domain care of the Library of Congress (so go use it if you need to!). The original post is HERE at Vox.
I also wanted to mention that you'll see most of these characters are specific folk heroes and not really fairy tales or fairy tale characters. In fact, that's one of the really interesting things about this map. Each of the names below the region is linked to an expanded explanation (usually Wikipedia) so if you were ever curious, here's your key to begin your study. (I've put some thought on this in the following post).
