if the rumor is true and if fairies are really elves, then that might explain the elvishness about Frodo?

Actually I think it's just one of those fairy-tale elements that show up in Hobbit. There really don't seem to be any fairies or sprites or other little things in the LotR universe. They got written out fairly early on, IIRC the proper History of Middle Earth reference. Probably hobbits just have fairy tales like we do, and it's just a story to explain the weirdness of the Tooks. Like medieval humans had "changelings", maybe.

Probably so. It seems that Frodo is often described as having an "elvish air about him" or that he looks elvish at times. Faramir notices it, Sam too when he leaves him in Shelob's lair and also the orcs think he looks elvish when they find him. I just wonder why all these references to elvish in Frodo...

Who's weird? It's the rest of the world that's weird!
