Avery is a hugely popular name in the US, especially for girls. But while nearly four times as many girls as boys are named Avery today Avery's popularity is starting to soften for girls while it continues to strengthen for boys.

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.

Ellie first took off in the UK—yes, in this nickname form—and this warm and friendly name has also become hugely popular here. In 2011, Ellie entered the US Top 100 girl names for the first time and has remained near the top of the charts ever since.

Bridget is the Anglicized form of Brigid, an Irish-Gaelic name that was derived from the word brígh, which means "strength."

Bonnie is an adorable nickname name, heading back up the popularity list after a 50-year nap. A Top 100 girls' name throughout the rest of the English-speaking world, Americans are later to jump on the Bonnie bandwagon but now it's trending here too.

This is a charming name that rose steeply along with other-belle names, such as Isabelle, until the horror film Annabelle and its sequels knocked it out of favor. Made famous by the Edgar Allen Poe poem Annabel Lee. Annabelle is saucy and stylish, a tad upscale, has a sense of humor, is melodious and lively, but is unfortunately off its peak.

Isabel derived from Elizabeth in southwest Europe during the Middle Ages. It was originally written as Elisabel, but the first syllable was dropped as it spread across the continent. In Spain and Portugal, Isabel and Elizabeth are considered to be variations of the same name, but they are treated as separate names in other European countries and the US.

For a long time, Isadora has been overlooked in favor of Isabella, owing perhaps to its association with the tragic modern dancer, Isadora Duncan, or because parents would rather their daughter be a Bella than a Dora. Now, with Theodora back in the charts and vintage names in vogue, Isadora has been slowly gaining more attention over the last decade.

Vanessa was invented by writer Jonathan Swift for a lover named Esther Vanhomrigh—he combined the first syllable of her last name with the initial syllable of her first. Swift used it in the poem Cadenus and Vanessa in 1713. A century later, Johan Christian Fabricius used Vanessa as the name of a genus of butterfly.

A place name with a deep Southern accent, the once-obscure Savannah shot to fame, with others of its genre, on the heels of the best seller Midnight in the Garden of Good and Evil, which was set in the mossy Georgia city of Savannah. Originally a substitute for the overused Samantha, Savannah is now popular itself, long among the top girls' names starting with S.

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.

Upbeat nickname-name that can't help but make you smile. You might want to use it as a short form for a more "serious" name such as Sunniva, but Sunny is undeniably, well, sunny.

This flower name was one of the most popular in her class in the seventies and eighties, a fact reflected in the 1989 movie Heathers, in which every snobby girl in the high school clique bears the name. Now, though still pretty and evocative of the Scottish moors, it has faded in favor of other purplish blooms. It fell out of the Top 1000 in 2016 after having been as high as Number 3 in 1975, when it was given to close to 25,000 girls. Across the pond in the UK however, it remains near the latter end of the Top 1000.

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.

Maggie is a cute, earthy short form that has been in style for several decades now, still sometimes used as an independent name by such parents as Jon Stewart. First used in Scotland, it got a large bump in popularity via the 1971 Rod Stewart hit song "Maggie May." Today's Maggie might just as well be short for a more adventurous name such as Magdalena or Magnolia as for the classic Margaret.

Maggie Gyllenhaal was born Margaret.

Originally inspired as by eighties TV actress Mackenzie Phillips, parents since have flocked to Mackenzie for their daughters. Now a staple All-American choice, Mackenzie has ranked in the US Top 1000 for nearly 50 years.

Mackenzie originates from the Scottish surname which itself an anglicized form of the Gaelic Mac Coinnich. Coinnich is one of the original Gaelic forms of Kenneth meaning "handsome, beautiful, comely".

Bethany is a lyrical name that still strikes many parents as a fresher, more substantial substitute for the overused Brittany/Brittney or the more antiquated Beth.

Thanks to Mariah Carey, everyone now knows this name – and is aware that Mariah's pronounced with a long i – just as Maria was in the Jane Austen era. And though Mariah now sounds modern, it was heard as far back as 1550 in Great Britain.

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.

Though perhaps not as currently stylish as Ruby, Jade, or Pearl, Amber has a colorful history (remember the notorious Forever Amber heroine?). Unfortunately, it does come with the "Amber Alert" connotation for modern parents (and their children).
