I don't know whether my DD's name is unusual enough for you - CENDRINE (it's French, meaning Cinders or Ashes which comes from Cinderella ... mind you i wasn't a huge fan of the meaning, LOL )

... Last year i met a little girl named Ocean (the more i said it the more i really like it)

By the way, your DS's name Kynan was my 1st choice for a boy's name when preg but i had a girl ... Oh, i just love that name
