Zooey
The original Zooey, hero of J.D. Salinger's Franny & Zooey, was male, but nowadays the name is more closely associated with actress/singer Zooey Deschanel. With Zoe at number 31 for girls and Zoey in the Top 50, the related Zooey feels more female than ever. But it's distinctively quirky for either sex.
