Harper got its start as a celebrity baby name when Paul Simon chose it for his now-grown son.
Harper as a girls' name has been growing in popularity over recent years, but when it was chosen for their first daughter's name by superstars Victoria and David Beckham, it really hit the big time. Certainly To Kill A Mockingbird author Harper Lee had a hand in this as well. It is now more commonly given to girls than boys. In the US in 2015, the girls name hit Number 10, whereas the boys name is at 722. In England and Wales the figure was at 89 for girls and unranked for boys.
