My SIL is Irish, so the names are unique here but are very common in Ireland.

Aoife (eefa)
Aisling (ashling)
Audrey
Aoife is the name we have chosen if this baby is a girl. I love Roisin too but my husband can't get pronounce it properly. I'm Irish so Aoife is a name I heard a lot growing up. Our daughter is called Ciara, pronounced like Kiera (Knightley). My spelling of the name (with a C) is actually far more typical than the K spelling. Sadly everyone pronounces it Key-ara or See-ara, because of that singer from the States. I hate the fact the people might think I called her after some pop star!.

Have to say most of my Irish mates think it's a bad idea for me to use Aoife, because it's so hard to pronounce and spell for Aussies, but every Aussie i've asked about it has loved it! You see so many strange and wonderful spellings of names over here that I guess everyone is far more open minded to unusual names.
