Alcyony is just misspelled. Alcyoni could work. In the case of most (if not all) Greek names ending with
e, the
e is interchangeable with
i. For example, I know a Greek girl named Nefeli, which is the modern form of
Nephele.
I also clicked on your profile and saw that you've submitted a massive amount of names, most of which are... not names. Cherrished? Gwenishia? Stelluh (as an "Anglicised" version of
Stella)?! Most of your pronunciations are either unclear or incorrect, also. Not to be rude, but maybe you shouldn't do that. I think user submitted names are supposed to be names that are actually used by real people, or that are at least etymologically legitimate. Just so you know. :]
