Zoya nail polish names.

Once a macho biker name, Harley is now showing its softer side. In the UK, Harley is predominantly masculine, but it's currently more popular for girls than boys in the US.

You might think of Harper as the hottest name of the last decade, jumping from obscurity to the Top 10, where it remained until last year.

Hayden – a formerly obscure name that's risen to huge popularity – has dipped in this year's ratings. Though Hayden is among the most distinctive of the bunch, it gets lost in the crowd of Jaidens, Bradens, Aidans, and endless variations. Associated with Hayden Christensen, of Star Wars fame.

This flower name was one of the most popular in her class in the seventies and eighties (in the 1989 movie Heathers, every snobby girl in the high school clique bore that name). Now, though still pretty and evocative of the Scottish moors, it has faded in favor of other purplish blooms, having fallen out of the Top 1000 after having been as high as Number 3 in 1975, when it was given to close to 25,000 girls.

Heidi became known—and popular—via the 1880 eponymous children's classic by Swiss writer Johanna Spyri and, despite decades of American Heidis of all sizes, shapes, and personalities, the name seems permanently tethered to that spunky little girl on the Alpine mountaintop in the book and Shirley Temple movie.

Hudson has risen quickly up the charts over the past 30 years, getting a lot of its style value from New York's Hudson River. That makes it a nature name and a place name that's also got the fashion gloss of New York City.

Hunter has been dropping a bit for the past few years but is still one of the leaders of a distinctive band of boys' names that combines macho imagery (Hunter, Austin, Harley) with a softened masculinity.

The quirky, offbeat and energetic botanical name Ivy is enjoying a deserved revival, propelled even higher by its choice by high-profile parents Beyonce and Jay-Z for daughter Blue Ivy. Ivy is also traditionally used at Christmas, make this one of the perfect names for December babies.

Jacqueline originated as a feminine form of Jacques, the French variation of James, and therefore Jacob. Jacob was ultimately derived from the Hebrew name Ya’aqov, and gets its meaning, "supplanter" from the story of Jacob supplanting his brother Esau as the first-born son in the Bible. Jacqueline was first used in France in the Middle Ages.

No, we don't consider Jane too plain. In fact, for a venerable and short one-syllable name, we think it packs a surprising amount of punch, as compared to the related Jean and Joan.

There was an eighties cartoon queen named Jem (& The Holograms), and this is as likely to be a full name as a short form – deriving from Jemma, Jemima or Jameela.

Stuck in the shadow of the old Dolly Parton song. In spite of its dated feel, Jolene reentered the charts in 2010 and has been rising in recent years.

A feminization used more before Jordan joined the girls' camp.

Pervasive in all Spanish-speaking cultures, Juanita, like Juana, has not emigrated.

Kara and the soundalike (though not necessarily related) Cara are among the most multi-cultural names around. Cara has roots in Latin, Italian, Irish, Spanish, and Portuguese, and Kara can be viewed as simply as K-starting version of Cara.
