I hope this list will help you find THE perfect Irish baby boy name for your little one. Maybe, if you are like me and don't speak Irish, you are finding it difficult to find the right Irish baby boy name because you can't figure out how some of the names are pronounced. It has audio files with pronunciation of a good selection of names.

Good luck finding your perfect Irish baby boy name! :)
