Girls

Hallie -- it rhymes with alley and is not to be confused with Halle or Hailey or Holly -- is one of those comfy nicknamish names that are in favor in these complicated times.

Zoey is a modern spelling variation of Zoe, the Greek Jewish translation of Eve. For a few years, it was even more popular than the original Zoe, but has now dropped back to the second-ranked spelling — not by much, however. In a recent year, Zoe ranked at #29 in the US, which Zoey featured at #59.

When Jennifer finally gave up her Number 1 place on the girls' popularity list, her crown was passed to Jessica, who reigned for not one but two decades. Jessica was the Number 1 name in both the mid-1980s and 1990s, never sounding quite as trendy as its predecessor, maybe because of its classic Shakespearean pedigree.

As Meghan/Megan and Reagan/Regan show signs of wilting, along comes Teagan to take up the slack: definitely one to consider. The vast majority of American babies named Teagan are now girls. A variant spelling is Teaghan.

Morgan has long been a traditional Welsh male name, a variant of the Old Welsh name Morcant, from the Welsh elements mor, meaning "sea" and cant, "circle." The female Morgan is unrelated to the male version—it is a name from Arthurian legend created for Morgan le Fay, King Arthur's half-sister and famed sorceress. Her name comes from Morgen, an Old Welsh name meaning "sea-born," and is related to the Irish name Muirgen.

Crisp and colorful, Autumn is the most popular season name in the US — the only one in the Top 100 in recent years — though Summer and Winter don't rank too far behind. Cool and gentle at the same time, it also ranks highly in England and Wales.

Sweet and sunny but substantial too, Callie is a nickname-style choice that has long been used as a stand-alone option . Traditionally a diminutive of classic Caroline, it may also be used for Calliope, Camila, Callista, Calanthe, and beyond.

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.

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.

Tatum is strong, distinctive, energetic, and recommended, especially if your last name is as congenial as O'Neal. The name is now used for both genders, with the balance running about two to one in favor of the girls.

Brooke has long projected an aura of sleek sophistication, and can also be seen as a stylish water name.

Light and glittery, but with plenty of spirit, Kinsley has risen quickly into the US Top 100. Balanced between preppy and cutesy, it feels like a fresh alternative to Kelly, Kaitlyn, or Kimberly.

Alana, in all its various spellings, was at one time reserved for daughters of dads named Alan, but is now much more widespread. It came into prominence via model/actress/celeb spouse Alana Hamilton Stewart.

Though it sounds like a chopped-off variation of Olivia, which means olive, the distinctively attractive Livia has been an independent name since the days of the ancient Romans, when it belonged to Livia Drusilla—the powerful wife of the Emperor Augustus—and is still commonly heard in modern Italy.

Delia is a somewhat neglected southern charmer that stands on its own but also might be short for Adelia or Cordelia.

Lilah may be a simple spelling variation of Lila— itself an alternative form of the Arabic Leila — or you might think of it as a shortening of Delilah or an Anglicization of the Hebrew Lilach, which means lilac. Whatever the root, it's a beautiful and stylish name. The final h adds balance or creates needless complications, depending on your viewpoint.

The combination of Emily and Emma's popularity -- and the fact that Desperate Housewives star Teri Hatcher's daughter is named Emerson -- have put this formerly strictly boys’ name, embodying the gravitas of Ralph Waldo Emerson, in the limelight for girls.

Monroe is a presidential name which, thanks to the immortal beauty of Marilyn Monroe, is catching on fast for baby girls. Mariah Carey and Nick Cannon chose it for their twin daughter, honoring Marilyn Monroe. Their use of Monroe as a girls’ name did much to revive this Old Man name, a la Sydney, as a newly fashionable choice for girls.

Widely used here since the 50s, Allison — a derivative of Alice — has now been once again surpassed by the original Alice as parents embrace vintage revivals. Despite this, Allison's popularity has slipped only slightly.

Haven is a recently invented safe-harbor name that appeals to an increasing number of parents who don't want to voyage quite as far as Heaven.
