Declan John and
Maren Cecilia are wonderful combos with good flow. I don't like
Camden that much, but
Camden Henry sounds good to me. I think
Henry makes a very good middle name.
I
really dislike
Cameron on a girl, but if you are going to use it, use
Cameron or
Camryn. Camren is very confusing. Since
Cameron is so masculine (IMO) I would use
Camryn for a girl because it will be perceived as more feminine. I think Camren
Emma is the best combo.
BTW, if someone introduced their son and daughter as
Keegan and Camren/Cameron, I would have no idea which one was the boy and which one was the girl. That's one reason why I dislike those kinds of names on girls.
