Harper is a red hot name for girls, having jumped an impressive 30 places between 2011 and 2012, a prime example of the trend for using surnames-turned-boys'-names for girls. Harper was rarely heard for either sex before the mid-2000s, entering the girls' list in 2004. (For boys, it was in use until 1906 when it dropped off the scope and didn't reappear until a full century later.)

Harper has been a shooting star in the celebrisphere, chosen first by Ali Wentworth and George Stephanopoulis, followed by Lisa Marie Presley, David Spade, Dave Grohl, Martie Maguire, Tiffani Thiessen, and Neil Patrick Harris. And now that the Beckhams have chosen it for their first daughter, Harper is sure to get even hotter.

It was To Kill a Mockingbird author Harper (born Nelle Harper) Lee who brought this family name into the public consciousness as a female first name with offbeat, boyish southern charm, and it's also a name with a musical bent. Harper has recently been used as a female character name on such hot TV shows as Gossip Girls and The Wizards of Waverly Place.
