Percy Jackson/Heroes of Olympus Names

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.

Hazel has a pleasantly hazy, brownish-green-eyed, old-fashioned image that more and more parents are choosing to share. Former Old Lady name Hazel reentered the popularity lists in 1998 and now is near the top of the charts.

Leo is a strong-yet-friendly name that was common among the Romans, used for fourteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

Nico is one of the great nickname names, full of charm, energy and effortless cool -- a neo Nick.

Luke is a cool-yet-strong Biblical name with a relaxed cowboy feel, which has been on the rise since the advent of Luke Skywalker.

Michael was the Number 1 American boys' name for almost half a century. While Michael has moved out of the Top 10 baby boy names, it's still widely used.

Percy is an adorable old name that is finally shedding its pampered Little Lord Fauntleroy image in this new era of boys with soft yet traditionally male names like Jasper and Elijah. Originating as an aristocratic Norman name, Percy became fairly widespread in England--and to some extent in the US--as an offshoot of the fame of the poet Percy Bysshe Shelley.

Juniper is a fresh-feeling nature name -- it's a small evergreen shrub -- with lots of energy. A new favorite of fashionable parents, Juniper joins such other tree and shrub names as Hazel, Acacia, and Willow.

Charles derives from the Germanic name Karl, meaning "man" or "free man", and is a royal name in multiple European countries. A famous early bearer is Charlemagne, King of the Franks and Lombards and then Roman Emperor in the 8th-9th centuries.

Connor, the appealing name of an early semi-legendary king of Ulster in Irish mythology, sits firmly in the Top 100 and taken together with its alternate spellings would rank even higher. In its native Ireland the Conor version is one of the highest charting boys’ name.

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.

A Top 10 name from the 1880s until the 1920s, Frank has been falling for decades but last year reversed course for the first time in a century, edging up the popularity list a few notches. And Frank still has a certain warm, friendly real-guy grandpa flavor that could come back into style, like other such choices as Jake and Jack.

Jason, the Number 3 name for the entire decade of the 1970s -- thus the title of our original baby-naming book, Beyond Jennifer & Jason -- is more likely to be dad's name now than baby's, but it's still a widely used name.

Bianca, the livelier Italian and Shakespearean version of Blanche, has been chosen by many American parents since the 1990s, just as Blanca is a favorite in the Spanish-speaking community. Its meaning of white relates to snow, making it one of the prime names for winter babies.

Thalia was one of the Three Graces in Greek mythology, and also the Muse of comedy and pastoral poetry, making this a Hellenic choice worthy of consideration.

Sally is a cheerful, fresh-faced girl-next-door name that was originally a nickname for Sarah, but has long been used independently. Sally was popular in the eighteenth century and then again from the 1920s to the 1960s--it was just outside the Top 50 around 1940. Though it hasn't been heard as a baby name for decades, we can see Sally bouncing back, especially after her exposure as young Ms. Draper on Mad Men--the Nameberries rank it at Number 621, and it's a Top 100 name in Sweden.

Friendly mega-popular short form of Katherine that has definitively replaced Kathy, Katie is often given on its own. Going forward, though, Katie is more stylishly clipped itself to the grownup Kate.

While Gwen may have originated as a short form of Gwendolen and Gwendolyn, these days it frequently stands on its own. Rocker Gwen Stefani has given it a shot of cool, and parents are choosing it as a standalone more and more often—Gwen hopped back onto the US Top 1000 in 2013 after an absence of over 30 years. Gwen could also be short for Guinevere.

Drew is an elegant formerly male-only alternative to Andy that joined the stylishly upscale Paige-Brooke-Blair sorority, thanks largely to Drew Barrymore. Barrymore comes by her first name legitimately: it was the maiden name of her paternal great-grandmother, Georgiana 'Georgie' Drew Barrymore, one of many esteemed actors in her family history.

Has a laid-back rural feel some would associate with country singer Travis Tritt; Kyra Sedgwick and Kevin Bacon chose it for their son. Travis Scott, born Jacques Webster Jr., a popular rap artist, is another famous Travis.
