I love Harper! It is very popular right now but for good reason.
I like Harper but only for girls...
It sounds rather masculine so I prefer it on boys. It's shot up for girls but I find it unattractive
I've never met a male named Harper. Seems like a girl name to me. I guess I don't really follow celebrity gossip, because I wouldn't have made the Beckham connection. The only Harper I can think of besides Harper Lee is the best friend character on the tv show Wizards of Waverly Place (no, I'm not a teenager, my niece used to watch that show).
I think it's an okay name, just not really my style. Harper Rebecca sounds nice.
