The problem with this is that many people will see it as a creative spelling of
Alex which I very much dislike. ah-LEEX is lovely but I can't stand
Alex on either gender. I like
Victoria and
Matilda as middle names. Not so much
Amelie. If you spell
Irène with the accent you want to pronounce it the French way, I guess? Might be difficult if you live in an English speaking country. I guess most people will still say eye-REEN.
