This is my name, and it's generally pronounced Muh-ray by Americans. I personally don't like that pronunciation, and I'd much rather people pronounced it 'correctly'--a matter of opinion--Mee-ray is much nicer.
This name is so beautiful. I used to believe that it was pronounced "mee-relle" or "mee-rayl" or something like that, but a French friend of mine set that straight for me. It is pronounced "mee-ray".
