So we think we have a short list. Dh wanted an Irish name, I was unsure but have managed to find some that don't sound too Irish. Also don't want ones that we or anyone else would struggle to pronounce. So:
Oscar (front runner, and to my surprise has a venerable Irish history, a warrior from Irish mythology, the name spreading worldwide and now known everywhere. However I am concerned from reviewing Internet that it's now too popular although I don't know anyone with that name, and dh worried cos his friend's dog is called Oscar)
Cass
Art ( dh concerned this will make people think of Arthur though it is a seperate unconnected name)
Iarla (not sure about this)
Setanta (again like its origins in Celtic mythology but the football channel is a problem)
Other ones I liked were ferdia, though dh didn't, also though of ultan, but I'm not sure.
Any thoughtson the short list everybody? We live in Ireland so comments - eg re popularity - from other Irish particularly welcome
