I love the Celtic names. Ones I've used are boy's names: Fergus and Rhys (pronounced Reese). Don't forget Ryan's Hope, the old soap opera: Siobban (sha-von), Maeve.
I'm playing a legacy with Jessica Rabbit as the founder (because she looked like the femme-fatale in Roger Rabbit). Rabbit seemed an appropriate last name for a legacy, so I've been having fun with names:
Girls: Bunny, Velveteen, Angora, Flopsy, Mopsy, Cottontail, White
Boys: Jack, Peter, Frank (Donnie Darko), Harvey, Thumper, Welsh (play on rarebit), Stu (hehe), V.W., Br'er, Killer, Crusader, Roger, Dutch, Hop, Lop, Uncle Wiggly
