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.

There are no less than ten different variations of Hailey on the current Most Popular list, but this is the spelling that brought it into the Top 10 of 2010, although it has quickly fallen in popularity. So, although Hailey has a shiny, unpretentious charm, its mass popularity makes it very much of the moment.

At the height of the Jennifer craze, many parents were cutting straight to the nickname and putting Jenny on the birth certificate. But now that Jennifer is the mom rather than the daughter, Jenny, which has been somewhat replaced by Jenna, has faded as well.

Reggae master Bob's surname was one of the biggest risers on the popularity charts for girls in 2008, with spellings Marlee and Marely also leaping in favor. Also used for boys, Marley is one of the top unisex names in the US.

One of the first luxury brand names and the quintessential Booming Eighties status-conscious moniker; used by Donald Trump for his daughter, Tiffany has plummeted far from its high in the Top 25.

Once the quintessential bouncy teenager name, Kelly helped launch the trend of unisex Irish names . But it now takes a backseat to more substantial surname names like Kennedy.

Brittany first arrived on the US popularity list in 1971, and rapidly zoomed up the charts, in the Top 100 a decade later. By 1986 it had entered the Top 10, becoming the third most popular girls’ name in the country by 1989.

Shirley Temple almost single-handedly lifted the gloom of the Great Depression, and in tribute (and perhaps wishing for a similarly curly-headed, dimpled darling of their own), thousands of parents of that generation gave their little girls her name. In 1935, Shirley was the second most popular girls' name in the country with more than 42,000 babies named Shirley.

One of the original unisex Irish surname names, energetic Casey bounced onto the scene in the 1960s, then peaked in the 1980s for both boys and girls. Today Casey is having a resurgence for both girls and boys and re-entered the charts on the girls' side, likely due to the character Kayce Dutton (pronounced like Casey) on the hit show Yellowstone.

A key cheerleader in the nickname game of the 1970s, Stacy is now the mom. Consider Stacia, or the original Anastasia.

One-time overnight success name, thanks to Hannah Montana actress and singer Miley Cyrus, Miley fell just as quickly from her peak of Number 127 in 2008 as the star entered her rebellious era.

You can't get much more feminine, sweet, and ladylike than Lady. Would make a cute nickname for up-and-coming Adelaide. Lady will also bring to mind the canine lover of the Tramp.

Hillary is a lovely name that, for the moment at least, is tightly bound to an individual with a strong image: Hillary Clinton. Whatever your feelings about Mrs. Clinton, her fame now dominates the name, making it feel less baby-ready than it deserves to be. Hillary as a name has so much going for it: the popular, rhythmic three-syllable structure, the fact that it's strong but light, proper but jaunty, with an irresistible meaning -- having the same root as hilarious. The Italian Ilaria may be one way to make the name fresh.

Sky may be a bit hippie-ish, but it's bright and sunny nonetheless. Sky rejoined the Top 1000 in 2013 after spending many years off the list. Sky was the choice of magician David Copperfield for his daughter, born in 2010.

Lindsey is one of the few truly unisex names (rather than being a name that has changed genders). Over time the "ey" ending was usually reserved for women and the "ay" ending reserved for men, and that tradition has continued

Hilary (also spelled with two 'l's) is a hot potato of a name, so closely identified with Sen. Clinton that it's hard for most parents to see it as a baby name. A pity, really, as it's got so much going for it: the popular, rhythmic three-syllable structure, the fact that it's strong but light, proper but jaunty, with an irresistible meaning -- having the same root as hilarious.

The alcohol-laced member of the Randy-Candy-Mandy sorority of 1970s to 80s nickname names; now pretty much on the wagon.

Glory sounds fresh and uplifting and a lot more modern than Gloria (which is definitely feeling the stirrings of a revival, though some might still view it as a terminal Old Lady name). Glory, as in "Glory Be" and "Old Glory," has both a religious and a patriotic flavor.

Stacey is a feminine name (though also used for boys) with Greek origins, derived from Eustace, meaning 'fruitful' or 'productive.' Initially a diminutive of Anastasia, meaning 'resurrection,' Stacey emerged as an independent name in its own right. The name reached peak popularity in the United States during the 1970s and 1980s, becoming emblematic of that era. Stacey conveys a friendly, approachable quality while maintaining a certain spirited energy. While its usage has declined since its heyday, the name retains nostalgic appeal and continues to be appreciated for its pleasant sound and unpretentious charm. Various spelling variations exist, including Stacy and Stacie, each offering slight personalization while preserving the name's essential character.

This abbreviated spelling, which also relates to Whitney, quickly took on a life of its own, thanks to the megafame of Britney Spears, but it's already beginning to burn out.
