Yeah, when I first saw it I thought it I thought it was Irish because of the Adh part. My sister is doing a biography on Céline Dion for school, and she was wondering how to pronounce Céline's father's name. It says that he was born in Québec, but maybe his parents were Irish? I can't find info on him anywhere. The é is pronounced ay as in day, so it's probably closer to the AYM-mur sound. Although it'd closer in spelling to Aodhmair, which makes it more confusing.
Funny, I remember posting a thread on how to pronounce Aedammair not that long ago! heh lol!
