Eww . . . boys. ALL GIRLS!!!

Charlotte, the name of the young Princess of Cambridge, is the latest classic name to join Sophia, Emma, Olivia, and Isabella at the top of the popularity list. It is now among the most popular girl names in many English-speaking and European countries.

Iris has so much going for it. It's a fashionable flower name. It's a mythological name, from the Greek goddess of the rainbow. And it's a classic name, always ranking in the girls' Top 1000 but now at its highest point ever.

Ava is one of the prime examples of a modern classic name, rising thought the course of a generation into the Top 10, where it has lingered for nearly 20 years.

Elizabeth is one of the most popular girls' names of all time, the female equivalent of James or William. Yet Elizabeth has so much going for it—rich history, broad appeal, and timeless style—that no matter how many little girls are named Lizzie, Eliza, and Beth, you can still make Elizabeth your own.

Caroline is a perennial classic, one of the elite group of girls' names that's ALWAYS ranked among the Top 1000 and that's been in the Top 100 since 1994. Elegant yet strong, Caroline calls to mind the Kennedy Camelot years and Princess Caroline of Monaco.

Isabella has been a Top 10 name for girls in the US for two decades now. The Latinate form of Isabel, a variation of Elizabeth which originally derived from the Hebrew name Elisheba, Isabella reigned as Number 1 in 2009 and 2010.

Cecilia is a lovely classic name deservedly enjoying a new turn in the sun. Always among the Top 500 girls' names in the US, Cecilia is now at its highest point ever.

Sadie started as a nickname for Sarah, but their images couldn't be more disparate. Where Sarah is serious and sweet, Sadie is full of sass and fun.

Hannah is one of the nation's top biblical girls' names — it surpassed Sarah in 1998, and ranks in the Top 100 along with Elizabeth, Abigail, Chloe, and Naomi. Hannah is a name with many sources of appeal: Old Testament roots, soft and gentle sound, and a homey yet aristocratic image.

Sophia, which was the Number 1 girls' name in the US from 2011 to 2013, is among the top girl names in the Western World, with a sensuous sound and high-minded meaning. A real winner, Sophia reached the top of the charts without losing any—okay, much—of its sophisticated beauty.

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.

Riley—an upbeat, friendly surname name—is red hot for girls and still going strong for boys. If you haven't been spending much time around babies recently, you may be surprised to learn that Riley is the most popular girls' name starting with R and also the Number 1 Irish name for girls in the US.

Sarah was derived from the Hebrew word sarah, meaning "princess." Sarah is an Old Testament name — she was the wife of Abraham and mother of Isaac. According to the Book of Genesis, Sarah was originally called Sarai, but had her name changed by God to the more auspicious Sarah when she was 90 years old.

Victoria is the Latin word for "victory" and a feminine form of Victor. It is the name of the ancient Roman goddess of victory, the equivalent of the Greek Nike, and also a popular third century saint.

Since we wrote a book called Beyond Jennifer & Jason, Madison & Montana, encouraging parents to move beyond overused names, it's no secret what we think of this trendy surname name, inspired by a mermaid named Madison in the 1980s movie Splash.

Nicole was derived from Nicholas, the English variation of the Greek Nikolaos, composed of the compounds nike, meaning "victory," and laos, "people." The variation Nicole arose in the Middle Ages in France to honor St. Nicholas. Names related to Nicole include Colette, Nicolette, Nika, Nicola, and Nicolina.

Jennifer is the Cornish variation of Guinevere, which ultimately derived from the Welsh name Gwenhwyfar. It has been in use in the English-speaking world since the 18th century but came to prominence in the 20th. Playwright George Bernard Shaw chose Jennifer for the name of his leading lady in his play The Doctor’s Dilemma, which drew more attention to the name.

Everything ella, from Ella to Bella to Arabella, is red hot right now. Bella is one of the most, well, beautiful girl names starting with B. It carried a hint of a nice Old World grandmotherly veneer, until it became attached to Twilight's Bella Swan.

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.

Selena is smooth, shiny, and sensual, a nineteenth-century name that found new life in the Latino community, following the biopic of slain Tejano singer Selena Quintanilla, starring Jennifer Lopez. But you don't have to be Latin to love Selena, which is both distinctive yet in step with stylish modern names such as Seraphina and Celia.
