For some years I thought that, over in England, any woman with that name was always eye-REE-nee (like the second principle character of the Forsyte Saga by John Galsworthy), and never eye-REEN.
Now I'm watching this super-popular Sherlock series (my friends made me; it ain't my fault; I don't watch TV) ... you know the one I mean, with what's his name, and I'm beginning to have doubts.
I looked it up. Turns out, both versions are in use in Britain. Check this out: How to pronounce Irene Adler
Is Miss Adler eye-REEN or eye-REE-nee? Do please enlighten me.
