[Opinions] Re: Iris... but on a boy.
It's similar to Osiris and Cyrus, so I can see why you think the sound would work.
If I think about it.... Hmm, I am not sure. The problem is I like it for a girl, and Iris is like the name Helen, it's very firmly a mature woman's name in my mind. Not much wiggle room there.
If I stop thinking of flowers and goddesses and instead look at it as a word for the coloured part of the eye, ok, I can wrap my head around it. Iris. Hmm.
