Unnamed List

Alyssa was in the Top 20 from 1997-2010 and peaked as the 11th most popular girls’ name in 1998 and 1999 but has become less popular in recent years. It's related to the flower alyssum as well as to the classic Alice and variants. Alyssa Milano helped give it a bounce back when she was still a child sitcom star.

Ann, the name of the sainted mother of the Virgin Mary, was among the top girls’ names for centuries, in both the original English Ann spelling and the French Anne. Both left the Top 100 around 1970 and show no signs of returning, with Anne is the middle of the US Top 1000 and Ann dropped out of sight.

Ariel is a male Biblical name, seen there as the messenger of Ezra, and also used as a symbolic name for the city of Jerusalem, while Shakespeare used it for a (male) sprite in The Tempest.

While not as popular as the Ariel spelling of Little Mermaid fame, this rendition has achieved popularity in its own right.

Ashley was a sensation in the 1980s and 1990s; it hit Number 1 in 1991. Ashley is still pretty but more and more parents are turning to newer names like Ashlyn and Aubrey, and spellings such as Ashleigh and Ashlea. If you hear the name Ashley in a playground today, it's more likely to be the mom than the little girl.

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.

Spelling this name with a y instead of the conventional way -- Bailey -- makes it a tad more feminine and also adds a touch of water. Baylee is another popular feminine alternative.

Though a couple of its more "creative" spellings—Carli and Karlee, for example—are still on the rise, this feminine form of Carl, popularized by singer Carly Simon in the 1970s, could by no stretch be considered fashionable. Despite its decline, the name has still seen some use in the entertainment industry, from Nickelodeon's iCarly to Canadian pop singer Carly Rae Jepsen.

Very popular surname choice — it's in the Boys' Top 100 — beginning to catch on for girls. First female association: novelist Carson McCullers.

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.

Chelsea is still being used, with about 400 baby girls named Chelsea in the US last year. But it was much more popular a few decades ago, peaking at Number 15 in 1992.

Chelsea was last fashionable around the time First Daughter Chelsea Clinton was born, ranking in the Top 25 in the early 1990s.

A Native American tribe name which is found in the names of two US states, Dakota was one of the first trendy nineties place names, but is now flagging a little in popularity. The cultural question around using a Native American tribe name as a baby name may be partly to blame.

Delaney has been a popular surname-style choice since 90s, when it joined other Irish surnames such as Cassidy, Kennedy, and Mallory on the US Charts. Buoyant, bright, and cheerful, it ranks in the US Top 250 and is given to nearly 1300 babies every year.

Dylan still feels poetic and romantic after years of popularity. It still ranks highly on the charts, among the top boy names starting with D, so if you choose it, be aware that yours may not be the only Dylan in his class.

Boys' favorite retains more of its poetic, windswept quality when used for a girl, as Robin Wright and Sean Penn did. Alyssa Milano gave her daughter Elizabella Dylan as a middle name.

Eliza is a name with a wonderful combination of streamlined zest and Eliza Doolittle charm and spunk. It's a classic that's popular right now -- but not too popular.

Elizabella is a much more obscure smoosh than sisters Isabella and Annabelle, but the megapopularity of Isabella may give this unusual combo name a boost.

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.

Combine the charming heroine of the movie Legally Blonde with supermodel Elle Macpherson and the trend toward all names beginning with "el"—Ellie, Ella, Eleanor—and you have one hit name.
