Miss Hamwich if you're nasty.
Go here to try the hobbit name generator: http://www.chriswetherell.com/hobbit/.
What I love most about it is that Viva's name "translates" to Dimple. Her true name, that is. If you use Viva, her name translates to Bramblerose. I kind of like Dimple better. And Sweet William must now and forever answer to "Bungo." HA!
Okay, so maybe I'm kind of behind the times in discovering this (it has apparently been around since 2000), but you know, I think all it proves is that The Lord of the Rings is timeless.
Fly, you fools!
