Some interesting replies here, Thank you all! I hadn't actually thought to try Googling it myself as I assumed it was most likely rather unique, although 14 billion hits would suggest something quite the contrary! That on it's own is a good reason to not choose a word such as this one. As I'm British myself it seemed some of the variants I heard actually had a French influence; i.e. one pronounced it as "En-yoh", another more "ein-yoh". The pronounciation two people unknowingly shared was as above; "eye-nee-on".

As for a meaning of 'Angels', that's very interesting; it's amazing how some supposedly random words can have such a beautiful meaning.
