Adeline has a lovely, old-fashioned "Sweet Adeline" charm, but has become so popular in the US under so many spellings and variations -- with Adalynn and Adalyn also popular -- that considered together it is far more popular than it first seems. Adorable nickname Addie is also pervasive. 
Adeline originated as a French diminutive of Adele, which came from the Germanic root adal, meaning "noble." Adeline was introduced to England by the Normans in the eleventh century, was very common during the Middle Ages, then vanished until the Victorian Gothic revival. Common variants of Adeline include Adalynn, Adalyn, Adelyn, Adelynn, Adelina, and Adaline.

 The song "Sweet Adeline" Is an old barbershop quartet favorite. JFK's grandfather John F. Fitzgerald, mayor of Boston, made it his theme song, and Mickey Mouse serenaded Minnie with it in a 1929 cartoon.
 Pronounced ad-a-line in America, it's usually ad-a-LEEN in France.

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).

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.
 
In medieval times, Ava was a diminutive of Germanic names beginning in Av-, in particular Aveline, from which the name Evelyn would eventually arise. It may derive from a Proto-Germanic root meaning "island" or "water". However, the medieval name eventually fell out of use entirely, only to resurface in contemporary times. 
 
This suggests that today’s Ava may be a modern variation of Eva. Alternatively, Ava could also derive from the Latin avis, meaning "bird." Ava has separate Persian roots as a name meaning "voice" or "sound."
 
Ava was given a huge popularity boost—Ava's currently among the <a href="https://nameberry.com/popular-names/nameberry/girls">top girl names</a> and the top <a href="https://nameberry.com/search/girls-names/a">girls' name starting with A</a>—when dozens of high-profile stars such as Reese Witherspoon and Hugh Jackman chose Ava for their daughters. Another reason for its appeal: It's one of the elite group of <a href="https://nameberry.com/list/607/girl-names-that-mean-life">girl names that mean life</a>. This Glamour Girl name via Hollywood beauty Ava Gardner is attractive but epidemically popular! 
 
Some parents who love Ava's simplicity and style have looked on to other choices that might take her place: Eva, Avery, Ada, Aveline and so on. The result, as with other popular names such as Hailey and Aiden that have spawned a raft of imitators, is that Ava is beginning to feel even more ubiquitous than it might otherwise based on its Top 5 standing. 
 
Ava seemed to be headed towards Number 1—it's no accident we titled one of our books on baby name style Beyond Ava & Aiden—but, though it seems to have been somewhat side-swiped by the Olivia-Isabella-Sophia group, it will still certainly stay in the Top 10 for years to come. It's a lovely name on many levels, but if you want something that will stand out, keep looking. 
 
One of the most fascinating things about Ava is that it's a much more ancient name than its modern-feeling sleekness would suggest. St. Ava was the daughter of King Pepin and was cured of blindness and became a nun. 
 
While Ava Gardner represents the Golden Age of Hollywood image of the name, director Ava DuVernay updates it to new Hollywood, together showcasing the name's attractive mix of glamor and strength.

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.

Unlike many gender-neutral surname-y names popular today, Avery began life as a first name and later became a patronymic last name. It originated in the Middle Ages as a Norman-French pronunciation variation of the Anglo-Saxon name Alfred and the Ancient Germanic name Alberich. The elements aelf, meaning "elf" and ric, meaning "ruler" give Avery its meaning. 
 
Angie Harmon and Jason Sehorn may have started it all when they chose it for their daughter in 2005, just as they did with daughters Finley and Emery. Amy Locane used the name in 2009 and now Dr. Phil has a granddaughter named Avery.
 
On 30 Rock, Elizabeth Banks had an extended cameo playing Alec Baldwin's glamorous fiancée, Avery Jessup.

Constance is one of the more subtle of the virtue <a href="https://nameberry.com">baby names</a>, but still has quite a prim and proper image. One impediment to its revival has been the decidedly dated nickname Connie, though modern parents might well opt for using the strong and dignified name in full.
 One of William the Conqueror's daughters was named Constance, and in Shakespeare's King John, Constance is the devoted mother of King Arthur. Constance was widely used in the seventeenth century by Puritans: Constance Hopkins was a young passenger on the Mayflower.
 The fictional Constance Billard School appears in TV's Gossip Girl, and Constance was the first name of the decidedly non-prim and proper Lady Chatterley.
 Oscar Wilde's wife was Constance, and Mozart's spouse was the German form Constanze, nicknamed Stanzi.
 Though Constance has been neglected here for a number of years, it's still ranks at Number 120 in France.
 Trivia tidbit: Constance was the birth name of 1940's peekaboo-hairdo star Veronica Lake and also, not surprisingly, Connie Britton.

Crimson could be a possible competitor for Scarlett's success, though it's lacking that Johansson charm.
 
Crimson tends to be disproportionately popular in Alabama — the University of Alabama's athletic teams are called Crimson Tide.

Eleanor's straightforward feminine image combined with its royal medieval history is striking just the right note for parents in search of a girls' name that combines substance and style.
 
Big plus: Eleanor is a serious name, with two nicknames—Ellie and Nell/Nellie—that are seriously endearing. Nell is more distinctive, but Ellie is undeniably one of today's top <a href="https://nameberry.com/list/508/cute-baby-names-for-girls">cute girl names</a>.
 While some think Eleanor is a variation of Helen via Ellen, it actually derives from the Provencal name Aliénor, of highly-debated meaning. It may come from the Germanic name Adenorde, meaning "ancient north" or "noble north". Another theory is that it derives from the Latin phrase alia Aenor, meaning "other Aenor," used to distinguish some original Eleanor, who was named after her mother Aenor. Queen Eleanor of Aquitaine brought it from France to England in the twelfth century. Other spellings include Elinor and Eleanore.
 
Diane Lane has an Eleanor, and Katie Couric has an Elinor, using the variant spelling. (Jane Austen used both versions—Eleanor in Northanger Abbey and Elinor in Sense and Sensibility.)
 
A notable namesake is First Lady Eleanor Roosevelt. Two other English queens bore the name: the wives of Henry III and Edward I. Eleanor Shellstrop was the protagonist of television show The Good Place.
 
Eleanora and Leonora are pretty, more feminine variations. Ellen and Lenore are shorter forms.

Eleanor

Elise is one of those golden names that stylish but not TOO popular. Its appeal is due in large part to its French flair and to the love for El-names in general.
 
Elise originated as French diminutive of Elizabeth but is now most commonly used as self-contained name. In English and French speaking countries, Elise is pronounced with two syllables, but in countries with Germanic or Scandinavian languages it is pronounced with three syllables, closer to Elisa. 
 Elise was introduced into the English-speaking world in the late nineteenth century. Today, it can make an original, modern honor name for an ancestral Elizabeth.
Emily Blunt played a character named Elise in The Adjustment Bureau. Fur Elise is one of Beethoven's most popular piano pieces. Piers Morgan named his daughter Elise.

Elise

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. 
 
Elizabeth is derived from the Hebrew name Elisheva, formed by the components ’el, meaning "God," and shava’, "oath." In the Bible, Elizabeth was the mother of John the Baptist, and two of England's most notable queens have been Elizabeth I and II. Another memorable bearer was Elizabeth Taylor—who hated to be called Liz.
 
Elizabeth nicknames on the table today include Libby, Bess, Tibby, and even the so-antiquated-it's-cool Betty. Also in play is the fashionable Eliza along with Lilibet, Queen Elizabeth's childhood nickname more recently used by Prince Harry and wife Meghan for their daughter, Lilibet Diana. 
 
Author and publishing magnate Zibby Owens introduced her zippy Elizabeth nickname to the ever-lengthening list of variations.
 
There has been only one year since 1880 that Elizabeth slipped one place below the Top 25, and that was in 1945—when Betty was Number 11. Today, it holds fast as one of the most classic and usable <a href="https://nameberry.com/search/girls-names/e">girl names starting with E</a>.
 The Elisabeth spelling, found in several cultures, is represented by such notables as Elisabeth Kubler-Ross, Elisabeth Shue, Elisabeth Moss, and Elisabeth Hasselbeck. 
Elisabeth is nicknamed Bethsy in Buddenbrooks, Bep in The Diary of Anne Frank, and Betsy in Wolverine.

Elizabeth

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.
 
Ellie derived as a nickname for names beginning with El-, such as Eleanor, Ella, and Elizabeth. In fact, Ellie's biggest downside is that it's used as a nickname for so many names, and given so frequently on its own, that you are sure to hear it far more than you might guess. Ellie is the standard spelling, but Elly and Elli are occasionally seen as variations.
 Ellie also has surprising international range, ranking highly not only in English-speaking countries but throughout Scandinavia and in Belgium and Switzerland.
 Ellie has been making many media appearances. Most recently, she's the young heroine played by Bella Ramsey in The Last of Us, based on a popular video game. Ellie has also been seen in the animated film Up, on The West Wing, and even as a woolly mammoth in the film Ice Age: The Meltdown.

Ellie

Because of Gwyneth Paltrow, this has almost become a one-person name, but not in the prohibitive there's-only-one-Oprah sense. Also seen as Gwenyth and Gweneth, this mellifluous appellation is definitely becoming more and more appreciated by American parents-- enough to land it on this year's Top 1000.
 Gwyneth is an Anglicized form of Gwynedd, the name of an ancient Welsh kingdom. Gwyneth Jones is an acclaimed Welsh Wagnerian soprano.

Gwyneth

The most modern choice in this group, and the most distinctive; the Gwyn form is a common male name in Wales. 

Gwynn

You might think of Harper as the hottest name of the last decade, jumping from obscurity to the Top 10, where it remained until last year.
 
Victoria and David Beckham's choice of Harper for their youngest child and only daughter in 2011 did much to catapult the name to stardom. Some reports say Harper was named after a character on Disney's Wizards of Waverly Place, her brother's favorite show, while other say she was named after Harper Lee, author of To Kill A Mockingbird, her mom's favorite book.
 
Those two influences definitely helped propel Harper up the popularity list in general. Plus Harper is a member of the trendy group of occupational surnames turned first names for both genders, including Taylor, Parker, Mason, and Skylar.
 
Harper has been a shooting star in the celebrisphere, chosen first by Ali Wentworth and George Stephanopoulis, followed by Lisa Marie Presley, David Spade, Dave Grohl, Martie Maguire, Tiffani Thiessen, Bill Hader and Neil Patrick Harris. Singer Paul Simon used it for his son more than 50 years ago.
 
While Harper was used near-exclusively for boys in the 1800s and remains technically unisex, in reality it's used today overwhelmingly for girls. More than 8000 baby girls were named Harper in the US last year, versus only 138 baby boys.

Harper

Helena is one of those classic names that just misses making the US Top 1000 girl names for its entire history, falling off for a single year in 1992. Since then it's been drifting lazily up the charts, and makes a perfect choice if you want a name that both fits in and stands out.
An airier and more elegant version of Helen, Helena was a favorite of Shakespeare, who used it in both All's Well That Ends Well and A Midsummer's Night Dream. 

Historically, Helena was the mother of Constantine the Great (and, supposedly, the daughter of Old King Cole), who became a fourth century saint--Evelyn Waugh wrote his only historical novel, Helena, based on her story.
 British star Helena Bonham Carter and Danish model Helena Christensen have done much to keep the name alive, and it is also remembered via beauty mogul Helena Rubinstein. Helena is also the title of a song by the group My Chemical Romance.
 Helena is a recommended <a href="https://nameberry.com/girls-names">girls' name</a> for those who find the classic version a bit bland.
 HELL-ehn-a is the best modern pronunciation for Helena, but hell-AYN-a or even hell-EEN-a work too.

Helena

Katniss Everdeen is the heroine of the popular Hunger Games trilogy by Suzanne Collins, whose name comes from the (very real) edible aquatic plant of the genus Sagittaria. Katniss's father tells her that if she "finds herself," she'll never go hungry. 

Other unusual botanical names in the series include Primrose, Posy, Rue, and Clove, all for girls. Several of the boys' names come from ancient Rome: Cato, Seneca, Flavius, Caesar.

Katniss the name has less appeal than Katniss the heroine, though it's definitely more attractive than Renesmee.

Katniss

Lila is one of the <a href="https://nameberry.com/girls-names">girl names</a> with a double l sound — Lila, Lola, Layla, Leila, Lily et al — that have caught on in a major way., Delicate yet dynamic, Lila has a slightly international flair.
 
The one caveat, and you may consider it a big: As a group, the La-La names have gotten so stylish so quickly that they're verging on full-blown trendiness and tend to blend into one another. So while there may not be another little girl named Lila in town, between those named Lillian, Lily, Layla, and so on, you may feel there's a double L overload.
 
Lila was derived from the Arabic word laylah, meaning "night." It has separate roots in Sanskrit with the meaning "play." In Hinduism, Lila is a conceptualism of the universe as a playground of the gods. Lilah and Lyla are variant spellings. 
Lila has been a recent hot TV character name, seen on such shows asDamages and Dexter, as well as Friday Night Lights, where the name is spelled Lyla—another trendy version.
 Trivia tidbit: Diane Sawyer was born Lila Diane.

Lila

Lori, with this sleek modern spelling, was an extremely popular name in the middle of the 20th century, ranking among the Top 100 girls' names from the early 1950s until the early 1980s.
 
But it was that very popularity that sent the name plummeting in popularity, as all the Baby Boomers named Lori began having babies of their own, making Lori (and Laurie) a mom name.
 
As Lori waned, Lauren rose, reigning at the top of the charts from the eighties through the oughties.
 
And now that Lauren too is becoming a mom name, what's taking its place? Classic Laura, matriarch of all the Loris, Lauries, and Laurens, is showing signs of revival in the US and ranking in the girls' Top 100 in many diverse European countries, cultures, and languages.
 
So baby Laura named in honor on grandma Lori brings the name full circle -- with today's little Lauras perhaps naming their own baby girls Lori and Laurie.

Lori

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 <a href="https://nameberry.com/search/girls-names/s">girls' names starting with S</a>, right after longtime favorites Sophia and Sofia.F
Scarlett originated as an occupational surname, denoting a person who sold scarlet, a luxury wool cloth produced in Medieval Europe. The word is thought to derive from the Arabic siklāt, referring to silks dyed with kermes. The fanciest, favorite color was scarlet red.
 
 Sylvester Stallone's third 'S' daughter, following Sophia and Sistine, is Scarlet (one 't', as in the color) and The White Stripes' Jack White and Karen Elson also have a Scarlett, as do Molly Sims and Rob Schneider. The Mick Jaggers were ahead of the curve when they chose Scarlett for the middle name of their daughter Elizabeth in 1984.
 In the Margaret Mitchell novel Gone With the Wind, Scarlett was the main character's grandmother's maiden name—she was actually named Katie O'Hara. The name entered the Top 1000 in 1940, a year after the movie of Gone With the Wind was released. Scarlett has continued its winning streak, and is now firmly in the Top 20.
 One of the leading characters on TV's Nashville was named Scarlett O'Connor.
