I like boys to have nice names that will harmonize with a last name.........more common, as males seem to like that for themselves and others.........with a nice, short, manly "call" name, which I've listed down below..........this also helps with recognizing and writing when they go to school, as many boys have trouble with that at first.
Girls--
Laura
Katherine
Piper
Melanie
Maritza
Mary
Paula
Caroline
Jolie
Julia
Elizabeth
Gillian
Hope
Paige (yes, I like my own name.......I would consider using it as a middle for my child, but I love it as a first for others)
For girls, I feel you can branch out a bit more. I think it's nice to have a name with a bit more flair........either by being an absolute classic, or a not-every-day-but-isn't-it-pretty. I would shorten Katherine to Katie and Elizabeth to Eliza.......otherwise I'd use the forms listed.
