You might think of Harper as the hottest name of the last decade, jumping from obscurity to the Top 10, where it remained until last year.

Harper got its start as a celebrity baby name when Paul Simon chose it for his now-grown son. Since then, other famous parents have followed suit: musician Tim Finn and actor Cecilia Peck both have sons called Harper.

The Old Norse word for "harp", also designating the constellation Lyra (which means "lyre" in Greek). It's popular in Iceland, where it is also the name of the first month of summer in the old Icelandic calendar.
