My son's name didn't exist on the baby name finder here so i added it yesterday and it appears as the name of the day today !!
We have sort of made it up but not really.....I liked Keir or Kerr, OH liked Ciaran. Ciaran means the little dark one and we didn't think he would be little so we took the "an" bit which is the "little" bit and kept the Ciar - pronounced exactly the same way as Keir so everybody happy. :o)
