I would go for isis and
Azalea. I don't think they are that unusual . i live in Brighton, England and i know 2
Isis and neither have ever had any trouble. I think they also go nicely with
Oliver. They are beautiful and something unusual (but not made up) is a good thing.
Similar sounding (to my ear any way) are
IvyIrisIonaIslaAntheaAltheaAstrid (really like this - nearly used it myself)
Yazmin
Don't like
Hazel though sorryy. Also despite disliking the name for what it is it seems a bit trendy just now especially aftre
Julia Roberts used it
