Philippa is a prime example of a boy's name adapted for girls that was common as crumpets in Cornwall, but rarely heard stateside. That was before the advent of royal sister-in-law Philippa Middleton, who goes by the lively nickname Pippa.

The French-accented Pascal was historically used for sons born at Easter, and can make an interesting choice for a boy with Gallic roots arriving around that holiday.

An evocative unisex one-syllable name, Poe is most distinguished by its literary reference. Edgar Allan Poe was an influential American author and poet, credited with inventing the genres of detective and science fiction, which might provide inspiration for parents who are fans. And now its choice as the name of the hero played by Oscar Isaac in the new Star Wars movie is sure to catapult it from literary choice to major favorite.

Philomena is an earthy Greek name now used in various Latin countries. While it has felt simply clunky for many years, it's starting -- along with such sister names as Wilhelmina and Frederica -- to sound so clunky it's cool.

This simple, elegant name offers something for many kinds of parents, from writers and history buffs to photographers to Pennsylvania dwellers.

Pax, one of the variations of names meaning peace that are newly popular in these less-than-peaceful times, got a lot of publicity when chosen by Brad & Angelina for their Vietnamese-born son.

British-born novelist Plum Sykes has taken this rich, fruity name out of the produce section and put it into the baby name basket. It's more appealing than Apple, more presentable than Peaches. The French equivalent, Prune, is very fashionable there but would not fly with English speakers.
