Girls

In music, the term allegro means "quickly, lively tempo," which makes this quintessential Bohemian ballet dancer's name all the more appealing. Allegra is one of the most distinctive yet accessible girl names starting with A.

Bijou is a name that lives up to its definition -- a real jewel. Warning: not unheard of on poodles' dog collars. Actress Bijou Phillips is its best known bearer. It can also be spelled Bijoux.

The name of the tragic mythological Trojan princess who was given the gift of prophecy by Apollo, but was condemned never to be believed, Cassandra has been used for striking characters in movies and soap operas. Ethereal and delicate, Cassandra was in the Top 70 throughout the 1990s but is now descending in popularity.

Cooler than April, May, or June, but also a tad icy.

Dorothea is a flowing and romantic Victorian-sounding name which was popular in the early decades of the twentieth century, but has been off the charts since 1970. Definitely on the brink of a revival!

Now that Faye is back on the Top 1000 after a decades-long absence, its spelling variations are being revived as well. Fae was given to nearly as many baby girls last year as Fay and may be especially attractive as a middle name option.

Jean Harlow (born Harlean Carpenter), the original platinum blonde bombshell, was a symbol of 1930s glamour, a factor that first Patricia Arquette and then Nicole Richie and Joel Madden probably had in mind when they gave their daughters the distinctive surname name Harlow.

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.

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.

Indie is an independent-sounding nickname name that is in the Top 100 in Wales. As a diminutive, it's growing in popularity -- along with indie films, indie publishing -- and the reason some parents are choosing names like India and Indigo. The Indie version seems more feminine, while Indy as in Indiana Jones tends toward the boyish.

Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.

Ivory was last popular a hundred years ago. In 2013, it finally began to regain some momentum in the female rankings, reentering the Top 1000.

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.

The name of the Roman goddess of the moon, Luna is derived straight from the Latin word for moon, luna. Luna may be the name most likely to surprise someone from an older generation by its Top 10 status in the US and its widespread international popularity.

Though greatly overshadowed by the trendy Olivia, Olive has a quiet, subtle appeal of its own -- and is now enjoying a remarkable comeback. Olive is one of only four girl names starting with O on the US Top 1000. Cool couple Isla Fisher and Sacha Baron Cohen chose it for their daughter, reviving the name to stylishness, and now Drew Barrymore has a little Olive too, as has country singer Jake Owen.

A strong Greek name with pan-European charm, Petra is a relatively recent feminization of Peter, though it relates back to an incredible ancient city in Jordan that was rediscovered in the early nineteenth century.

Asking for trouble. Rebel Wilson is a hilarious Australian actress who puts a female spin on this contemporary badass baby name. Still, we think this name is truly gender neutral – though hardly neutral in any other way. Rebel is undoubtedly one of the edgiest girls' names starting with the letter R.

Scarlett Johansson is doing more for this sparky southern name than Scarlett O'Hara ever did. Since the turn of the 21st century, Scarlett has gone from an obscure literary name to one of the most popular girls' names starting with S, right after longtime favorites Sophia and Sofia.

This hauntingly euphonious Choctaw name has re-entered the public domain, as memories of the outrageous actress Tallulah Bankhead have faded. For years, Tallulah was a name associated only with Bankhead, named for her paternal grandmother who was named after the Georgia town of Tallulah Falls.
