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.
 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.
 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.

Alice is a classic literary name that's both strong and sweet, ranking in the US Top 100 and popular throughout the western world. Alice is derived from the Old French name Aalis, a diminutive of Adelais that itself came from the Germanic name Adalhaidis, which is composed of the Proto-Germanic elements aþala, meaning "noble," and haidu, "kind, appearance, type." 
 Alice is quite distinct among traditional <a href="https://nameberry.com/girls-names">girls’ names</a>—more feminine and dainty than Mary and Helen, more substantive than Ann or Jane, yet with more lightness and innocent charm than Margaret or Katharine. 
 
Alice has been riding a fresh wave of popularity, not only in the US and other English-speaking countries but in places as diverse as Italy, France, Brazil, and Sweden. That makes Alice a remarkably international choice.
 Alice is a darling of literature, from the immortal heroine in Alice in Wonderland to an unusual number of fine modern writers like Alices Munro, Walker, Sebold, Hoffman, McDermott, Adams, and Elliott Dark. In other fields, there were First Daughter Alice Roosevelt, painter Alice Neel, food innovator Alice Waters, and literary figure Alice B. Toklas, to name a few.
 As a British royal, Alice was Queen Victoria's second daughter, the princess who shocked her Victorian mother by breastfeeding her baby. More recently, Tina Fey helped popularize the name when she chose it for her daughter.

In music, the term allegro means "quickly, lively tempo," which makes this quintessential Bohemian ballet dancer's name all the more appealing. Allegra is one of the most distinctive yet accessible <a href="https://nameberry.com/search/girls-names/a">girl names starting with A</a>.
 One of the most creative sounding of names, Allegra has been associated with the American prima ballerina Allegra Kent, and has been chosen as a first or middle name for their daughters by poets George Gordon, Lord Byron and Henry Wadsworth Longfellow, as well as by R. Buckminster Fuller and Donatella Versace.
Caveat: There is that current connection to the allergy medication.

Allegra

Astrid has been a Scandinavian royal name since the tenth century, and many people associated it with the Swedish author of the Pippi Longstocking stories, Astrid Lindgren. Astrid is derived from the name Ástríðr, which is made up of the Old Norse elements that mean "god" and "beautiful." 
Related names include Asta, a diminutive used throughout Scandinavia, and Astride, the French form. Despite their similarities, Astrid is unrelated to Astra, a Latin name meaning "of the stars."
 
Astrid has never really assimilated into our culture the way Ingrid did, but with the renewed interest in international names, Astrid might be worth consideration by parents with Norse roots. 
 
Astrid is the name of the teenage heroine of Janet Finch's 1999 novel White Oleander and has appeared as a character in How to Train Your Dragon and the TV shows Fringe and Once upon a Time.

Astrid

Azalea is one of the fresher flower names, along with Zinnia and Lilac, that are new to the name bouquet — in fact, it entered the Social Security list for the first time in 2012. So if Lily and Rose are too tame for you, consider this brilliant pink springtime blossom with a touch of the unusual that has been growing in popularity. 
 Azalea is the name of the princess heroine of the novel Entwined, and, most recently, is connected to musical artist Iggy Azalea.

Azalea

Belinda, cousin of Linda and Melinda, enjoyed a brief return to the Top 1000 from 2005 through 2013, only to fall off again in 2014. A name that some may consider a modern spin on the midcentury popularity queen Linda is in fact a classic with deep and fascinating roots. In Babylonian mythology Belinda was the goddess of heaven and earth, and the name later was used for the heroine of Alexander Pope's satirical poem The Rape of the Lock.
 One of Belinda's meanings is 'beautiful snake' (coined at a time when snakes were a sacred symbol of wisdom and immortality) and it still does seem to have a certain lingering serpentine charm.
 Belinda entered the US popularity lists in 1940, and went on to reach Number 142 in 1961. Both Maria Edgeworth and Anne Rice wrote eponymous novels called Belinda.
 Belinda Carlisle was the lead vocalist in "The Go-Go's."

Belinda

Blanche, which originated as a nickname for a pale blonde and then became associated with the notion of purity, was in style a century ago, ranking in the double digits until 1920. She then had to fight the stereotype of faded Southern belle, a la Blanche DuBois in Tennessee Williams's A Streetcar Named Desire and Blanche Devereaux in TV's Golden Girls. Now all three of the Golden Girls--Blanche, Rose and Dorothy--could be ready for revival, with Blanche sounding like a stronger, simpler alternative to Bianca.
 A saint's name, Blanche was a royal name in France by the twelfth century, then was brought to England by the French wife of Henry I. One possible powerful namesake is Blanche Scott, one of the original daredevil aviatrixes. You might also take its meaning to relate to snow, making it one of the perfect <a href="https://nameberry.com/list/89/winter-baby-names">winter baby names</a>.

The name of the tragic mythological Trojan princess who was given the gift of prophecy by Apollo, but was condemned never to be believed, Cassandra has been used for striking characters in movies and soap operas. Ethereal and delicate, Cassandra was in the Top 70 throughout the 1990s but is now descending in popularity. 
 
Cassandra was the name of Jane Austen's mother, sister, and two cousins. Cassandra Wilkins is a character in John Dos Passon's novel Manhattan Transfer, but in the 2007 Woody Allen thriller, Cassandra's Dream, Cassandra was not the name of a person, but a sailboat. Currently, Cassandra Wilson is a noted jazz singer; Charlie Sheen has a daughter Cassandra born in the eighties.
 
Nicknames include Cass, Cassa, Cassie, Sandra, Sandy.

Cassandra

Cora is a lovely, old-fashioned girls' that has been recently rejuvenated by its contemporary-feeling simplicity. In fact, Cora seemed headed straight for the top of the popularity list when the coronavirus pandemic somewhat weakened its appeal.
 
Though she has never been completely out of favor, Cora has had her ups and downs. A Top 20 name in the 1880's, she had sunk to Number 876 in 1988 before reversing course yet again. A more recent inspiration is the appealing American-born Cora Crawley, Countess of Grantham on Downton Abbey. 
 
In classical mythology, Cora—or Kore—was a euphemistic name of Persephone, goddess of fertility and the underworld. Kore was the name used when referencing her identity as the goddess of Spring, while Persephone referred to her role as queen of the Underworld. 
 
Cora gained popularity as a given name after James Fenimore Cooper used it as the name of his heroine, Cora Munro, in his 1826 novel The Last of the Mohicans. 
 
While a complete name unto itself, some parents who love Cora may want to use it as a short form for such names as Cordelia or Coraline. Cora's fashionable sisters include Clara, Nora, Corinne, Corinna and Coralie.

Cora

One of the flower names, used occasionally in Britain (where it's pronounced DAY-lee-a). It seems to have recovered from what was perceived as a slightly affected la-di-dah air. The flower was named in honor of the pioneering Swedish botanist Andreas Dahl, which means dale.
 In the Victorian language of flowers, Dahlia denotes elegance and dignity.
 In P.G. Wodehouse's Jeeves stories, Dahlia is Bertie Wooster's more sympathetic aunt, described as being constructed along the lines of Mae West. Reporter Dahlia Lithwick covers legal matters for the online magazine Slate.

In Greek mythology, Daphne was the nymph daughter of Peneus, a river god. Peneus saved Daphne from Apollo’s romantic obsessions by transforming her into a laurel tree. It is from this myth that the plant genus daphne, which contains the laurel species, gets its name.
 
Daphne's origins may be Greek, but it's seen by Americans as quintessentially British—as in the Daphne Moon character on Frasier and the heroine of the romantic drama Bridgerton. The shrub inspired the popularity of the name in England, where it became part of the British vogue for plant names at the end of the nineteenth century. 

Though we don't see it becoming a Top 100 name in the US, Daphne is obviously finding more widespread acceptance—and for a distinctive, deeply-rooted, attractive girls' name, that's a positive thing. In fact, Daphne has been in the US Top 1000 for every year but two -- 1913 and 1938. And it's now at its highest point ever in the US and is also one of the most popular girls' names on Nameberry.
 Its most famous bearer is Daphne du Maurier, author of such suspense novels as Rebecca. Fictional Daphnes have appeared in Some Like It Hot (Jack Lemmon as a woman), The Jewel in the Crown, Scooby-Doo, Harry Potter, and Heroes.

Daphne

Edith was a hugely popular name a hundred years ago that's being revived among stylish parents in Stockholm and London. It's currently beginning to gain traction in the US among those with a taste for old-fashioned names with a soft but strong image. 
 The name of two American First Ladies, Mrs. Theodore Roosevelt and Mrs. Woodrow Wilson, as well as that of several early English queens, Edith is one of the oldest surviving Anglo-Saxon names. Widely used in nineteenth century novels, Edith was chosen by Louisa May Alcott for the heroine of her first novel The Inheritance, written when she was seventeen.
 Edith Wharton makes a fine literary namesake, with other noted bearers including poet Edith Sitwell, iconic Hollywood movie designer Edith Head, and for francophiles, there is the reference to Edith Piaf. With the rise of so many other E-starting names from Ella to Evelyn, and the adorable short form Edie, we predict that Edith will soon sound more like a cute toddler than a dated granny, especially with the Despicable Me character and the emergence of one of the most interesting characters on Downton Abbey, Lady Edith Crawley.

Edith

Maybe it's because she shares that winning -elle sound with Isabel and Bella, but Estelle is no longer seen as a muumuu-wearing canasta player of a certain age (think George Costanza's mother on Seinfeld or Joey Tribbiani's talent agent in Friends). This could be in part thanks to the young Royal Couple of Sweden, who chose it for their firstborn daughter, or the single-named British R&B singer. It reentered the US Top 1000 in 2012 after a nearly fifty-year absence.
 Latin version Estella, introduced in Great Expectations, also has energy and charm, while Estrella is another stylish member of this star-related club. Ali Landry has a daughter named Estela. Este and Estee are also in the wind.

Estelle

Eve, the oldest name in the Book, is now coming back into style, having the virtues of simplicity and purity, yet with more strength and resonance than other single-syllable names like Ann. British actor Clive Owen chose Eve for his daughter, as did Jessica Capshaw. 
 
While Eve is compromised by its similarity to trendy sisters Ava, Eva, Avery, Evelyn, Evie, ad infinitum, it still has them all beat with its streamlined classic style.
 The rapper born Eve Jihan Jeffers goes by the mononame Eve.
 Fictional Eves have figured prominently in the films All About Eve, Three Faces of Eve, and WALL·E, and on TV in Angel and Xena: Warrior Princess.
 Eve is the anglicized form of the Gaelic Aoife.

Of all the botanicals, Fern has been one of the slowest to move back from the front parlor into the nursery, despite the appealing girl character in the children's classic Charlotte's Web. Fern was most popular from the turn of the last century through the 1940s, reaching a high of #152 in 1916. We can certainly see her rejoining the long list of popular greenery names.
 
Reality TV stars Jessa Duggar and Ben Seewald recently named a daughter Fern, which could easily give it a boost.

Fern

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

Iris has so much going for it. It's a fashionable flower name. It's a mythological name, from the Greek goddess of the rainbow. And it's a classic name, always ranking in the girls' Top 1000 but now at its highest point ever.
 
Iris is directly derived from the Greek word iris, meaning "rainbow." In Greek mythology, rainbow goddess Iris was a messenger for Zeus and Hera who rode the rainbow as a multicolored bridge from heaven to earth. 
 The botanical iris also carries evocative symbols. In ancient times, the Iris was considered a symbol of power and majesty, the three petal segments representing faith, wisdom and valor. This image led to the naming of the colored part of the eye.
In the contemporary world, Iris has amazing international versatility, ranking highly throughout the English-speaking world as well as in a diverse range of countries from Spain to Slovenia, France to Sweden.
 Part of Iris's rise is due to its celebrity power: Jude Law and Sadie Frost, Judd Apatow and Leslie Mann, and Renee O'Connor all chose Iris for their daughters.
 A notable modern bearer was the prolific British novelist Iris Murdoch. Frequently seen on screen, characters called Iris have been played by Jodie Foster, Jane Fonda and Kate Winslet, and Iris Chase is the narrator in the Margaret Atwood novel The Blind Assassin.

Iris

Lavender lags far behind sweet-smelling purple-hued sister names Violet and Lila, but is starting to get some enthusiastic attention from cutting-edge namers along with other adventurous nature names like Clementine and Marigold. 

 The flower's name derives from Latin lividus "bluish", influenced by lavō "wash" due to use of lavender in washing clothes. It has long been used in traditional medicine and in cooking for its sweet fragrance and soothing properties. But it also has a long history as a name, going back to the eighteenth century, when it was also used for boys. 

 Famous fictional namesakes include Lavender Brown, a witch character in the Harry Potter saga, and the eponymous heroine's best friend in Roald Dahl's Matilda.

Lavender

The name of the Roman goddess of the moon, Luna is derived straight from the Latin word for moon, luna. Luna may be the name most likely to surprise someone from an older generation by its Top 10 status in the US and its widespread international popularity.
Often ranked as Number 1 on Nameberry's internal charts, the strong but shimmery Luna is among the Top 100 names for baby girls in a wide range of countries around the world, from France to Italy to Germany, Scandinavia to Slovenia to Spain. It's simple, easy to spell and pronounce, and remarkably diverse.
 And it's also got deeper roots than you might imagine. It was somewhat popular in the US as a baby name around the turn of the 20th century, reaching a high of Number 403 way back in 1881.

Luna's popularity is undoubtedly influenced by the Harry Potter character Luna Lovegood and several high-profile celebrity babies, notably the oldest daughter of Chrissy Teigen and John Legend. 
 Along with its celebrity connections, Luna's popularity is partially driven by its standing as a mythological name. Luna’s divine complement is Sol, the god of the Sun. In Roman art, Luna is often depicted driving a chariot.
 
Luna makes another appearance as the endearing oddball Luna Lovegood in the Harry Potter series, who was central enough to the story to have Harry give his daughter Luna as a middle name, and as the True Blood teacher-shapeshifter character, Luna Garza. 
 
Along with Chrissy Teigen and John Legend, other celebrities who named their daughters Luna include Penelope Cruz and Javier Barden as well as Constance Marie. Joely Fisher and Ellen Pompeo have used it as a middle. Uma Thurman and Arpad Busson use Luna as the nickname they call daughter Rosalind Arusha Arkadina Altalune Florence.
 
Luna is also among the <a href="https://nameberry.com/popular-names/dogs">most popular dog names</a>.

Luna

Phoebe is the Latin variation of the Greek name Phoibe, which derived from phoibos, meaning "bright." In classical mythology, Phoebe is the by-name of Artemis, goddess of the moon and of hunting. The masculine version of Phoebe is Phoebus.
 
A mythological, biblical, Shakepearean, and Salinger name, the warm and captivating Phoebe was given a boost in popularity by one of the Friends.
 
In the New Testament, Phoebe is a church deaconess. Shakespeare used the name (spelled Phebe) for a rustic denizen of the forest in As You Like It, Phoebe Pynchon was a cheerful young girl in Hawthorne's The House of Seven Gables, while Phoebe is Holden Caulfield's sympathetic, precocious ten-year-old sister in Catcher in the Rye.
 Bill and Melinda Gates used Phoebe for their daughter.

Phoebe

Rosalind has a distinguished literary history – used and popularized by Edmund Spenser and Shakespeare via one of his most charming heroines, in As You Like It. Along with a bouquet of other Rose names, Rosalind might be ready for a comeback.

 Despite appearances, Rosalind is not technically a true Rose name. It originally derives from the Germanic elements hros "horse" and lind "soft, flexible, tender", but the spelling was later influenced by the appealing Latin phrase rosa linda "beautiful rose".

 Rosalind was at its height in the 1940's, coinciding with the popularity of the acerbic movie star Rosalind Russell: it was Number 293 in 1943, but fell off the list in 1978.

 Uma Thurman gave her young daughter five names, the first of which is Rosalind – though she is called by her nickname Luna.

Rosalind

Spelled with one 'n', this was the name of the wife of Alexander the Great, and is more attractive than the better-known Roxanne.

Roxanna

Serena, a name used since Roman times, was given fresh life by tennis star Williams, and then again with the leading character on Gossip Girl, Serena van der Woodsen. There have also been Serenas on soap operas and other shows from Bewitched to Law & Order.
 And pre-TV, there was the damsel in Edmund Spenser's The Faerie Queen and Serena Merle in Henry James's The Portrait of a Lady.

Serena

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.
 
Vanessa was one of the ultra-feminine three-syllable hits of the eighties, but has proved to have had more staying power than others like Tiffany, Kimberly, and Melissa, due to its classic beauty.
 Vanessa Redgrave is the doyenne of the renowned Redgrave family; Vanessa Hudgens, the young actor and singer from High School Musical is a more youthful bearer. On TV there have been Vanessas on The Cosby Show, Gossip Girl and Vampire Diaries.

Vanessa

Vera was the height of fashion in 1910, then was for a long time difficult to picture embroidered on a baby blanket. Now, though, it has come back into style along with other old-fashioned simple names such as Ada and Iris. 
 Vera was barely known in the English-speaking world until it appeared in the 1860 novel by Ouida, Moths, and Vera Rostov is a character in War and Peace, published nine years later.
 Vern Yip has a young daughter called Vera, and Vera Wang and Vera Famiga have modernized it. Vera Lynn was an iconic British World War II singer, Vera Miles was a Hitchcock star best known for her role as Lila Crane in Psycho and Vera-Ellen (born without the hyphen) was a dancing partner of Fred Astaire and Gene Kelly.
