Niamh is prodominantly pronounced 'NEEV', inside Ireland and outside, though there is another pronunciation, 'NEE-uhv' (the second syllable being quite briskly spoken). There's a cartoon character in an Irish commerical named Niamh and it's pronounced NEEV. That's the only pronunciation I've ever actually heard used. The 'NEE-uhv' pronunciation is supposedly heard in a few spots in Ireland and is not at all as popular as 'NEEV'.
I love Niamh. I think it's a beautiful name and one that I could see myself using for a future child. It's not at all bizarre.
