It's not a bad combo, but doesn't really compare to the ones you already have imo.
Reasoning: Well, I prefer
Ciaran to
Kieran, but I still like
Kieran a lot. nn
Kerry I find hard though, because again it doesn't seem to follow in my accent. (KEER-an to KEH-ree.) Also, I've only ever heard of
Kerry on girls.
Edward is great, but
Oliver booming in popularity, so I'm slightly sick of it at the moment. The names go well together though.
