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.

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.

Indie actress Parker Posey put a female imprint on this sophisticated surname that's still about three times as common for boys but rising for both sexes. Parker has the advantage of its nature connection, relating it to such occupational names as Gardener and Forester.

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.

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.

Peyton is a unisex surname that rose to fame in the 90s, with parents drawing inspiration from football star, Peyton Manning, and, oddly enough, from "Peyton Flanders", the villainess of the 1992 film, The Hand That Rocks The Cradle. Combining gentle sounds with contemporary style and the naughtiness of Peyton Place, the name remains a popular choice in the US today.

Presley is a much more popular name for little girls than you might think, entering the charts as a girls' name in 1998 and hovering around Number 200 for the last decade.

With a soft sound, a preppy feel, and a unisex style, Palmer is a last name that's been climbing up the charts for girls in the US. Having entered the Top 1000 in 2018, more recent stats place it in the Top 300. More than four times as many girls received the name than boys in 2023, though Palmer is a name on the rise all round.

Poppy, unlike most floral names which are sweet and feminine, has a lot of spunk. Long popular throughout the rest of the English-speaking world, Poppy is finally starting to rise toward the top in the US, where it entered the Top 1000 for the first time in 2016.

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.

Rarely used until the 90s, Payton rose up the charts when it was popularized by the football star, Peyton Manning, and, interestingly, by the character of "Peyton Flanders", the villainess of the 1992 film, The Hand That Rocks The Cradle.

Phoenix is a New Age name symbolizing rebirth and immortality. It's also a place name, a color name, a mythological name, AND an animal name, combining several of today's hottest trends in one appealing package.

Despite her somewhat prissy, puritanical air, Priscilla has managed to stay widely used for well over a century -- it reached as high as Number 127 in 1940 -- appreciated for its delicacy and solid history.

Paris, a one-time mythical and Shakespearean boys' name, peaked in 2004 at Number 157 at least in part due to the highly publicized Paris Hilton. Michael Jackson used it for his daughter.

Just when we thought Paisley couldn't get trendier, this -ee suffix showed up. Although it's not our favorite, parents are choosing this spelling more and more often.

Magical and earthy, sophisticated but off-beat, Persephone appears as the daughter of Zeus by Demeter in Greek mythology. After she was kidnapped by Hades to be Queen of the Underworld, it was decreed by Zeus that she would spend six months of the year with her mother, allowing crops to grow, and six in mourning, thus accounting for the change of seasons. As such, she is both the goddess of the Underworld and of Spring.

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.

Pearl, like Ruby, has begun to be polished up for a new generation of fashionable children after a century of jewelry box storage. The birthstone for the month of June, Pearl could also make a fresher middle name alternative to the overused Rose. Cool couple Maya Rudolph and Paul Thomas Anderson named their daughter Pearl Minnie, followed by Jack Osbourne picking Pearl Clementine. Several celebs have put it in the middle spot, as in Busy Philipps's Cricket Pearl, Jake Owen's Olive Pearl and Caleb Followill's Dixie Pearl .

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

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.
