-The Witch Must Die: How Fairy Tales Shape Our Lives by Sheldon Cashdan
I don't believe I had heard this before, I always assumed the name "Rumpelstiltskin" was a nonsense word, like his British counterpart Tom Tit Tot and the Scottish Whuppity Stoorie, etc. (He has also got by Trit-a-Trot, Terrytop, and more difficult names such as Holzruhrlein Bonnfurlein or Ferradiddledumday-see a list of related tales at Surlalune)
And although it can be confusing when talking about Snow White from "Snow White and Rose Red" verses the more famous Snow White of the Seven Dwarves variety, in German their names are not actually exactly the same. The Snow White who ends up in a glass coffin is actually "Little Snow White" from the German Schneewittchen. The one with sisterly affection has a slightly different meaning, "White as Snow." (Found in Fairy Tale Rituals by Kenny Klein)
EDIT: Apparently my sources may not have been exactly correct in these above factoids-see the comments for more
It may be gone by the time this is posted, but right after the release of Disney's "Maleficent", Dictionary.com opened up its main page with a featured link, "what does Maleficent mean?" The definition:
ma·lef·i·cent[muh-lef-uh-suhnt] Show IPA
doing evil or harm; harmfully malicious: maleficent destroyers of reputations.
Can be confused: maleficent, malevolent.
I think I always thought it was a combination of "magnificent" with "malevolent."

And last but not least-Tony once asked me if our English word "grim" came from the brothers Grimm. I hadn't thought so but it wasn't out of the realm of possibility. However, again according to Dictionary.com, the origin is from old English, before 900. So the last name of the famous brothers was just a coincidence, but heaven knows there are plenty of puns to go around :)
