Personally I would choose a first name that doesn't start with a k sound or end with a y sound and I'd drop your maiden name if you're not intending to use it (what is she gonna do when she gets married?). I'd maybe use Kelly as a middle name though, just without the hyphen. That's just me though and Carly is cute. Maybe you could use a long version of it for her official name? Charlene Kelly Kennedy? Charlotte Kelly Kennedy? Carlotta Kelly Kennedy?
What do you think of the name Carley for a girl? Her name would be Carley Kelly-Kennedy x
