I have a Ciaran too, but the poor lad - no one EVER spells his name correctly, even family get it wrong and many of his teachers at school can't seem to pronounce it either. He gets called See-ARE-an, and teased about having a girl's name.
Having said that, he's v. proud of his traditional Irish name and wouldn't change it for anything. He was pretty horrified when I told my first choice of name for him was Julian .
