Arizona

This unusual and evocative southwestern place name picked for his daughter by former Everclear frontman Art Alexakis. It popped up as a first name on the quirky Dr. Arizona Robbins, introduced on Grey's Anatomy in 2009, played by Jessica Capshaw.

Not so admirable namesake: the notorious criminal "Ma" Barker was born Arizona Clark. Though her name would not have been such a radical choice at that time--Arizona was widely used in the late nineteenth and early twentieth century, peaking at Number 510 in 1882--which was before Arizona became a state.
