Jon Freeman, as a speaker of Hiberno-English, I recommend the following site to hear names pronounced by the late Frank McCourt, a native speaker of Irish (Gaelige; NOT "Gaelic" which is Scottish).


Baby Names or Ireland w/audio pronounciation


If that site can't help, sometimes simply googling "how to pronounce _____ in Irish" and hitting enter will lead you to an audio file, often on youtube by native speakers.
