Credit the award-winning single-named British singer for taking the <a href="https://nameberry.com/girls-names">girls’ name</a> Adele from a quiet semi-retirement back into currency. Adele reentered the US Top 1000 <a href="https://nameberry.com/popular-names">popular baby names</a> in 2011 and has remained there ever since. 
Adele is both a saint's and a royal name, having originated as the French version of the German Adela. It's one of the most stylish <a href="https://nameberry.com/search/girls-names/a">girl names starting with A</a>. 
Molly Ringwald chose Adele for one of her twins, and Fred Astaire's first dancing partner was his older sister Adele.
 Historically, Adele was the name of the youngest daughter of William the Conquerer. Music lovers might associate the name with a character in Johann Strauss's operetta Die Fledermaus, while a prime literary reference is Jane Eyre's young charge.

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.

Aviva is vivacious and memorable, a fresh spin on the Vivian and Vivienne names that have been getting more popular since Angelina and Brad chose one for their twin daughter. Another A-beginning palindrome name: Aziza. 

Aviva

Common name in Wales that's all but unknown in the U.S.  Certainly an attractive choice ripe for export. In the UK it sits at Number 330. 

Cerys

Clara is a strong, lovely girls' name that's always ranked among the US Top 1000 girl names but has been climbing since the turn of this century. Now holding steady around Number 100, Clara is a modern classic, neither too popular nor too unusual.
 
Long relegated to an Olde World backwater, the European-flavored Clara was long less fashionable than sleeker sister Claire. Now, though the vintage chic Clara is still less popular, it's arguably the more stylish of the two names. 
 Clara was a Top 10 name in the 1880's, at one time associated with the silent screen 'It Girl,' Clara Bow, and before that with German musician and composer Clara Schumann and Red Cross founder Clara Barton, who was born Clarissa.
 Clara is beloved for her leading role in The Nutcracker ballet and as Heidi's invalid friend. Actor Ewan McGregor was an early celebrity adopter of the name for one of his daughters.
 Other Clara variations you might want to consider include Clarissa and Clarina, though Clarabelle seems still fit mainly for cows.

Clara

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 new 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 -- since 1880, the first year the US government recorded baby names. And it's now at its highest point since the 1960s.
 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

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

Eliza is a name with a wonderful combination of streamlined zest and Eliza Doolittle charm and spunk. It's a classic that's popular right now -- but not too popular.
 
Eliza has not been in the Top 100 since the 19th century and while it seemed like it was heading there again, it seems to have stopped just short of that mark. Which could be a very good thing.
 
Originally a diminutive of Elizabeth, Eliza eventually became a name in its own right. Despite its similarity to the Hebrew name Aliza, meaning "joyful," the two are unrelated. Eliza Schuyler Hamilton was the wife of Founding Father Alexander Hamilton, recognizable today as one of the lead characters in the musical Hamilton.
 Eliza is the name of one of the most vivid fictional characters, My Fair Lady's spirited Eliza Doolittle. Based on the George Bernard Shaw play Pygmalion, Eliza is transformed from cockney flower girl to elegant lady, played on stage by Julie Andrews and on screen by Audrey Hepburn. .
Pride and Prejudice's Elizabeth Bennett was often called Eliza; in Harriet Beecher Stowe's anti-slavery novel Uncle Tom's Cabin, Eliza is the intelligent and courageous protagonist
 Eliza Dushku is a charter member of the Joss Whedon rep company of actors, appearing in Buffy the Vampire Slayer, Angel, Dollhouse and Much Ado About Nothing. 
 One note: Do not name sisters Eliza and Isabel or Isabella, as they're different forms of mother name Elizabeth.

Eliza

Elliot is another traditional <a href="https://nameberry.com/list/79/boy-names-for-girls">boy name used for girls"</a>, a trend led by political commentator George Stephanopoulos and his actress wife Ali Wentworth. 
 Variously spelled Eliot, Elliot, Elliott and Elliotte (used by Marla Sokoloff), its star is definitely on the rise for girls. Bonus for girls is cute and feminine nickname, Elle. And many parents, of course, choose Elliot to get to the trendy short form Ellie or even Ella. At this point, Elliot has become one of the most popular <a href="https://nameberry.com/search/unisex-names/e">unisex names starting with E</a>.
 Dr. Elliot Reid was a female character on Scrubs.

Eva is a simple, classic <a href="https://nameberry.com/baby-names/489/hebrew-names-for-girls">Hebrew name for girls</a> that recently slipped out of the US Top 100 for the first time in more than a decade. Pronounced either like her more popular sister Ava or less popular sister Eve, Eva is one of the elite group of <a href="https://nameberry.com/list/607/girl-names-that-mean-life">girl names that mean life</a>.
 
Eva is found in many different languages as a variation of Eve—the Old Testament name recognizable as the first woman in Abrahamic religions. Short forms of the name include Evie and Evita. The diminutive Evita is still strongly associated with Evita Peron, wife of the Argentine President Juan Peron.
 The 1852 publication of Uncle Tom's Cabin, the bestselling novel of the nineteenth century, whose tragic figure Little Eva (short for Evangeline) made an enormous impression on the Victorian reading public, propelled the name to popularity.
 Some well known Evas include actresses Evas Marie Saint, Gabor, Green, Longoria and Mendes, sculptor Eva Hesse, singer Little Eva, and model Eva Herzigova
 Eva is a highly popular <a href="https://nameberry.com/girls-names">girls’ name</a> throughout the Western World, ranking in the Top 100 of most English-speaking countries along with a wide range of European nations, from Spain and Italy to France and Germany to Scandinavia. This makes Eva one of the most internationally versatile names today.

Georgia is so rich, lush and luscious, it's almost irresistible. Georgia's now a rising star among the feminizations of George, helped by associations with the southern state (named for British King George II) and painter Georgia O'Keeffe, with the Ray Charles song "Georgia On My Mind" or maybe "Sweet Georgia Brown" playing in the background. 

 Georgia is in fact a double place name, also belonging to an ex-Soviet state famous for the ancient monastery Vardzia and its rich culinary and wine-growing culture.

 Georgia has been chosen for their daughters by Harry Connick, Jr., Hope Davis, Amy Ryan, Zac Brown, Rebecca Gayheart and Eric Dane, and Felicity Huffman and William H. Macy.

Georgia

This flower name was one of the most popular in her class in the seventies and eighties (in the 1989 movie Heathers, every snobby girl in the high school clique bore that name). Now, though still pretty and evocative of the Scottish moors, it has faded in favor of other purplish blooms, having fallen out of the Top 1000 after having been as high as Number 3 in 1975, when it was given to close to 25,000 girls.

Laurel takes Laura back to its meaning in nature, resulting in a gentle, botanical option. Even more directly than Laura, Laurel relates back to the laurel wreath signifying success and peace in ancient Rome.
 Sweet Laurel has been the unlikely name of two DC Comics superheroes—Laurel Kent and Laurel Gand, aka Andromeda.
 Laurel received its highest ranking in 1956, when it reached Number 241. It may be due for a resurgence, thanks to the trend for <a href="https://nameberry.com/search/girls-names/l">girls' names starting with L</a>. Beware though, that it has the likelihood of being mistaken for Laura and Lauren.

Liana is a pretty and graceful name — it's a flowering tropical vine — that may be making a quiet comeback.

More than Lily yet less than Lillian, Lillia is a fresh and undeniably pretty member of the stylish genus of double (or in this case triple) l names.  You can also spell it Lilia.

Maia was derived from the Greek word maia, meaning "mother." In Greek legend, she was the fair-haired daughter of Atlas who mothered Zeus's favorite illegitimate son, Hermes.

Maisie, a charming name long popular as a nickname for Margaret or Mary, entered the Top 1000 as itself ten years ago and continues to rise. Game of Thrones star Maisie Williams helped propel the name back into the limelight, along with the that of her character, Arya.

In literature, Maisie is the name of the precocious young title character in the Henry James novel What Maisie Knew, and is also the main female character in Rudyard Kipling's The Light That Failed. And to bring things up to date, Maisie is a half-blood character in the Harry Potter series. Spelled Maisy, it's a popular children's book series.
 When Maisie re-entered the US Top 1000 in 2014 at 658, it was one of the fastest rising names of that year. She's still got a ways to go In the US to catch up to other English-speaking countries, where Maisie ranks in the Top 100.

Mirielle

Introduced to the American public by actress Neve Campbell; it was her Dutch-born mother's maiden name. Neve is an interesting and fresh new possibility, one which Conan O'Brien chose for his daughter.
Neve Campbell pronounces her name nehv, to rhyme with Bev or Lev. If taken to represent the Italian and Portuguese word for snow, the pronunciation would change to nehv-ay. As an Anglicized form of the Irish Niamh, the correct pronunciation would be neev.
New Zealand prime minister Jacinda Ardern chose the name Neve for her daughter, born while she was in office.

Neve

Sabina is a sleek but neglected name from an ancient Roman tribal name that's well worth consideration. The equally alluring Sabine is heard in France and Germany. Related names include the more popular Sabrina or Serena. All are equally lovely.
Sabina dropped off the US Top 1000 a century ago. Does that mean it's time for a comeback?
The Sabines were a tribe in Ancient Italy that went to war with the Romans. According to legend, the Sabine women were kidnapped by the Romans but later affected peace between the warring sides.
There have been characters named Sabina in Thornton Wilder's play The Skin of Our Teeth and the Milan Kudera novel The Unbearable Lightness of Being.

An ancient tree that figures in literature from Shakespeare to Harry Potter and is believed to possess magical powers, Willow is a lovely name, as graceful as its inspiration.
 Willow's use as a given name derives directly from the willow tree, whose name was derived from the Old English word welig, meaning "willow." Willow trees are associated with grace and elegance, which gave way to the adjective "willowy." Other names with meanings related to willows include Arava, Willoughby, Dozier, Wellesley, Selby, and Salton.
 
This elegant and charming nature name has been chosen for their daughters by Will Smith and Jada Pinkett Smith, Michelle Monaghan and Pink. It's been a fast riser in recent years, climbing along with other Will names Willa, William and Will, having taken off here a year after the character of Willow was introduced on Buffy the Vampire Slayer in 1997.
 
Willow is also popular in other English-speaking countries: Australia and the UK, Canada, Ireland, and Scotland.
 
The name has transcended its one-time hippie aura to move into the realm of reappraised and appreciated <a href="https://nameberry.com/list/329/nature-baby-names">nature names</a>. The willow is believed by the Romani to possess the ability to heal the sick and rejuvenate the aged.
 
Pink was quoted as saying her choice was influenced by a willow tree she grew up near, and that it is the most flexible tree that nothing can break—no wind, no elements, it can bend and withstand anything.
