I would put this name in my feminine name book, even though this spelling for Robin seems a little over the top. Robin is normally unisex, but personally, in my opinion, this isn’t a really good name for a boy. It’s better off on a girl. Robynne is way too feminine.
I don't know about this one. It's trying so hard to be unique, you'd be better off naming your daughter something that's actually unique. A robin is still a robin!
