Caerdhwyn
(CARE-dwin) I needed to make up a character name for a fantasy role-playing game, and I had heard something that sounded like this on an episode of "Highlander: the Series". It turned out that the name was actually Ceridwen, and is the name of a Celtic goddess of poetry (as I learned from behindthename.com), but I prefer my spelling. I think it sounds very pretty, and is definitely unique, as long as it doesn't get shortened to "Carrie"!
