Bubbly, bright, and versatile, Phoebe is a name with mythological, biblical, and literary ties. Used since the 17th century, it fell out of fashion in the US during the '60s, only to be revived after it appeared in the 90's TV favorite, Friends.

Penelope is an unlikely 21st century baby name success story. Off the Top 1000 for 25 years, Penelope jumped back on in 2001 and has been heading uphill ever since, propelled by the trend for mythological names, Spanish actress Penelope Cruz, and some high-profile celebrity babies.

Pippa, a peppy condensation of Philippa that turns it from serious to sprightly, has come into the public eye in a big way via the former Kate Middleton's sister.

Piper is a bright, musical name that entered the list in 1999, one year after the debut of the TV series Charmed, which featured a Piper, and it's been a consistent riser since. Piper Kerman is the memoirist whose prison experiences provided the basis for the hit Netflix series Orange is the New Black.

Paige is more name, and less word than the occupational Page. Paige is also sleek and sophisticated a la Brooke and Blair and reached as high as Number 47 in 2003, when there was a very popular television show, Trading Spaces, hosted by the energetic Paige Davis.

Paloma is vibrant and ruby-lipped a la jewelry designer Paloma Picasso, but it also suggests peace, as symbolized by the dove. Paloma is a highly recommended striking but soft name, one of the best of the names that mean peace and girls' names starting with P.

Pandora has occasionally been used by the British gentry (for girls with brothers who might be called Peregrine) and is now starting to be heard in the US too: It was given to 34 baby girls last year.

Pam was a somewhat pampered prom queen of the sixties who was never called by her full name, which is a pity because Pamela is so mellifluous and rich in literary history. A Top 25 name from the late 1940's through the late 60's, Pamela has just, sadly, dropped out of the Top 1000.

An alternative to the no-longer-fresh Molly, the initial 'P' gives Polly a peppier sound, combining the cozy virtues of an old-timey name with the bounce of a barmaid.

Patricia still sounds patrician, though its scores of nicknames definitely don't. Wildly popular from the forties (alternately Number 3 and 4 throughout the decade) to the sixties, Patricia has been fading ever since. But a comeback in its full form is definitely conceivable—just look at Penelope.

Prudence, like Hope and Faith, is a Puritan virtue name with a quiet charm and sensitivity that is slowly returning to favor, though it hasn't yet registered on the charts.

For a name related to a Scottish town, a patterned Indian fabric, and a country singer named Brad, Paisley has seen remarkable success. After appearing, seemingly out of nowhere, it is now an American favorite.

Like Peggy and Patsy, Penny is a peppy vintage nickname that fell out of favor (and the Top 1000) for a while, but has recently rebounded by reentering the charts in 2013. Expect it to continue gaining traction on the heels of Penelope.

Joining the likes of Coco and Fifi, Gigi has a style but some may feel it lacks substance. Model and TV personality Gigi Hadid (born Jelena) has likely drawn attention to this name, while designer Cynthia Rowley may have inspired parents to use it as a given name by choosing it for her daughter.

Perry fits right in with rising boyish nicknames for girls and cool picks like Frankie and Scottie. This relaxed name sounds novel compared to such former favorites as Kerry and Sherry.

Posey is fashionable in England, a country of gardeners, but this pretty bouquet-of-flowers name is only starting to be heard here.

Pauline had its moment of glory almost a century ago, when movie audiences were thrilling to the silent serial The Perils of Pauline; it's a sweet and gentle name that just might be due for reconsideration. Off the list since the late 1990s, Pauline was a Top 50 name from around 1908 to 1930.

After a long time in limbo, Prudence is now so clunky it'a cool, and it's starting to make a comeback, along with other Puritan virtue names like Mercy, Patience, and Constance.

A recently entered name on the roster, Poet was used for her daughter by Soleil Moon (Punky Brewster) Frye, who obviously appreciates the advantages of an unusual name. This is a possible middle name choice for verse-loving parents who want to skip specifics like Auden or Poe or Keats or Tennyson and go with the generic.

More stylish than either Paula or Pauline, it was given a glamour gloss by model Paulina Porizkova in the nineties.
