Calista Flockhart spotlighted this lovely Greek name that has a long future in the English-speaking world.  Kallista is another spelling; Calixta and Calixto are related.

Callista

Cecilia is a lovely classic name deservedly enjoying a new turn in the sun. Always among the Top 500 girls' names in the US, Cecilia is now at its highest point ever.
 
Cecilia is a feminine form of Cecil, which was derived from a Roman clan name related to the Latin caecus, meaning "blind". While that may put some parents off, we say put that ancient meaning aside and focus on Cecilia's symbolic resonance in the contemporary world as a classy and classic name.
 
The martyred Saint Cecilia was designated the patron of musicians, either because she supposedly sang directly to God while the musicians played at her wedding, or because she sang to God as she was dying. The name was popularized in the Middle Ages as an homage to the Saint.
 On TV, the Cecelia spelling variation was the name chosen for Pam and Jim's baby on The Office; in real life the name of the daughters of Vera Wang and Soledad O'Brien.
 Cecilia is also a Dickens character name in Hard Times, and appears in the novels Atonement and The Virgin Suicides, and The Hunger Games series, as well as being the subject of a memorable Simon & Garfunkel song.
 Cecilia, Celia and Cecily are all nameberry faves. Cecelia is an accepted spelling variation you may want to consider if you plan to shorten the name to Celia or Cece.

Cecilia

Claire, luminous, simple, and strong, is one of those special names that is familiar yet distinctive, feminine but not frilly, combining historical depth with a modern edge. And though Claire is enjoying revived popularity, it will never be seen as trendy. Claire is also a great middle name choice. 
 Claire is the French form of Clara, a feminine derivation of the Latin masculine name Clarus. The French word for "clear," Claire’s meaning, is clair, and was traditionally a male name. Now the spelling is used mainly for girls, along with Clare, and occasionally Klaire or Klare.
 
Claire is usually seen as the French spelling of the name, while the equally appropriate Clare is English and Clair is French too. Clara, once seen as a stuffier version, has lately gained some fashion edge, primarily because it has more vintage charm and is somewhat more unusual. The Italian Chiara is another recommended choice.
 
Famous women named Claire include the medieval Saint Clare of Assisi (who was made the patron saint of television in 1958 because of her reputed power to see events at a distance), writer Clare Booth Luce, silent screen siren Clara Bow, and actresses Claire Bloom and Claire Danes.
 
There have been countless fictional Claires as well, including ideal mom Clair Huxtable, Molly Ringwald's character in The Breakfast Club, Clare Kendry in Nella Larsen's novel Passing, and characters in House of Cards, Lost, Six Feet Under, Modern Family, and the Outlander series.

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.

Derived from the Old Irish name Dubhshláine, Delaney can mean "dark challenger" or "dark river" depending on which translation is used. Alternatively, it could be an English surname, taken from the Old French de l'aunnaie", meaning "from the alder grove".

Only ever given to a handful of babies each year since the early 1900s, Delaney leapt up the charts in the 90s, It's rise in popularity could be attributed to its similarity in sound or style to the likes of Mackenzie, Destiny, Kimberly, or Kaylee, or it may be that parents liked it as a fresh twist on Elaine and a new way to the nickname Lainey. 
 Alternatively, pop cultural influences might have driven the name up the charts, with singer Delaney Bramlett releasing new music, actress Dana Delany starring in the successful TV drama, China Beach , and the Delaney family in The Baby Sitters Club book series.

Delaney

Melodic and lively, Delilah has cut itself (mostly) free from its treacherous past to become a contemporary favorite. 
Though some people are naturally still put off by the deceptive Biblical figure, a large number of parents have been tempted by Delilah’s charms, meaning it now ranks in the Top 100 in the US, the UK, and Australia. 
Delilah is a Hebrew name, meaning “weak and languishing”, or, more appealingly, “delicate.” In the Old Testament, Delilah was the lover of Samson, but she betrayed him by cutting off the source of his strength – his hair – before handing him over to his enemies. 
Despite this negative namesake, Delilah has been occasionally used in the English-speaking world since the 1600’s when it was revived by the Puritans. 
It danced in and out of the charts during the 20th century, but by the mid 2000’s, it began to make significant gains. By 2018, it was in the Top 100, where it’s continued to rise ever since. 
With its alluring cadence, Delilah has been a hit in the music world. Camille Saint-Saens composed an opera based on the Biblical story in the 1880’s, while Tom Jones saw success in the 60’s with his song “Delilah.” 
Other artists who have sung about her include Queen, Chuck Berry, Sufjan Stevens, and Florence and the Machine, though it was after the release of the Plain White T’s song, “Hey there Delilah” that the name really jumped up the charts in 2007. 
Actors Harry Hamlin and Lisa Rinna were well ahead of the trend when they named their daughter Delilah back in 1998, and since then, it’s been a sparkling choice for celebrities. Kimberly Stewart, Benicio del Toro, Laurence Fishburne, Gina Torres, and Keira Knightley are among those who’ve selected Delilah for their daughters. 
Given to nearly 4000 babies every year, Delilah is still on the rise, while its international form, Dalila, remains popular in Italy and Bosnia and Herzegovina. 
If the sparkly, energetic sounds of Delilah do appeal to you, but the popularity or associations don’t sit right, then you could consider Tallulah, Keziah, Alaia, Azura, Talitha, or Fifer.

Delilah

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

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

In the past few years Ellery has gone from middle-aged male detective to a plausible girls' name, a la Hillary.


Ellery

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. 
 Hallie's popularity has had its ups and downs. It was well used in the first four decades of the twentieth century, then dropped out until the early eighties, and has been consistently used ever since.
 Singer Emmylou Harris has a daughter named Hallie.

Jean Harlow (born Harlean Carpenter), the original platinum blonde bombshell, was a symbol of 1930s glamour, a factor that first Patricia Arquette and then Nicole Richie and Joel Madden probably had in mind when they gave their daughters the distinctive surname name Harlow. 
 It hit the Top 1000 for the first time in 2009, one year after the arrival of Ms. Madden. Harlow would fit right in with contemporaries Arlo and Marlow(e).

Harlow

Popularized in the 1940s by Lana (born Judy) Turner, today Lana is synonymous with American singer-songwriter Lana Del Rey. Although it has been rising steadily since the early 2000s, Lana still sits in the popularity "sweet spot" – familiar, but not overused. Simple, sleek and seamlessly international, it makes a great choice.

Lana

A kind of old-fashioned nickname name that's enjoying some fresh life thanks to trendy brother Lane.  Lainie is a more old-school spelling.

Laney

Lark is getting some new and well-deserved attention as a post-Robin and Raven bird name. Although it was first recorded as a name in the 1830's, it has never appeared on the Social Security list.
 'The Lark' was used as a nickname for Cosette in Les Miserables; Lark Voorhees was a star of Saved by the Bell, and Jennifer Connelly and Paul Bettany used Lark as the middle name of their daughter Agnes.
 
The expression "happy as a lark" gives this songbird name a cheery image, as well as a 'lark' being a synonym for a merry time..
 Larkin is a pretty extension, as is Skylark, which is rich in cultural associations: there's the Percy Bysshe Shelley ode To a Skylark and the jazz classic Skylark written by Johnny Mercer and Hoagy Carmichael..

Lark

While Larkin takes this name from girlish bird to boyish surname, there are actually more female Larkins these days than male, and it's a name that works as well for either gender.

Larkin

Lavinia is a charmingly prim and proper Victorian-sounding name which actually dates back to classical mythology, where it was the name of the wife of the Trojan hero Aeneas, who was considered the mother of the Roman people.
 Later literary bearers include the protagonist's daughter in Shakespeare's Titus Andronicus (which has the line "She is Lavinia, therefore must be lov'd"), the heroine of G.B. Shaw's Androcles and the Lion, and characters in David Copperfield, Henry James' Washington Square, and the contemporary The Hunger Games and Downton Abbey--and Lavinia was also used by Thackeray, T. S. Eliot, and by Ursula Le Guin for an eponymous novel.
 Trivia tidbit: Lavinia was Ava Gardner's middle name.
With its vintage nickname Vinnie, Lavinia might well appeal to parents who favor lavender-tinged names like Amelia and Matilda and Maude.

Lavinia

A lovely (and uncommon) longer form for Nora, one of the most fashionable international nickname names around. Lenora fell off the US charts in the 70s, but just re-entered in 2022 as parents' love for short forms Leni and Nora is growing.

Almost exclusively associated with opera diva Leontyne Price.   If you want to use the suddenly-stylish Leontyne, we'd recommend the French Leontine spelling.

Lily is the most popular of the popular delicate century-old flower names now making a return, thanks to its many irresistible attributes: a cool elegance and a lovely sound, a symbol of purity and innocence, and a role in Christian imagery.
 Lily's use as a given name was a direct influence of the flower. The floral name was derived from the Latin lilium, itself derived from the Greek leirion. Lily later became an adjective to describe whiteness and purity.
 
 Lily is a favorite of celebrity parents, including Chris O'Donnell, Kate Beckinsale, Greg Kinnear, Fred Savage, and Johnny Depp and Vanessa Paradis (who made it a double bouquet, with Lily-Rose). The more proper Lillian is also rising in popularity, though Lily has long stood on its own. 
 Lily is an authors' favorite, some notable example being Lily Bart, the main character of Edith Wharton's House of Mirth, Lily Owens in The Secret Life of Bees and both mother and daughter of Harry Potter. Other current bearers are Lily Tomlin, singer Lily Allen, and actress Lily James. Two one-time starbaby Lilys are now celebrities on their own: Lily Collins, daughter of Phil, and Lily Rabe, daughter of Jill Clayburgh and David Rabe.
 Lily is currently quite popular throughout the English-speaking world as well as in France, Denmark, the Netherlands, and other European countries. Other possible spellings are Lilly, Lili, and Lillie.

A versatile classic, Lucy is both sweet and solid, a saint's name, and the heroine of several great novels. First fashionable in England and Wales, Lucy is now a popular choice in the US, The Netherlands, and New Zealand.
 
The English form of the Roman Lucia, Lucy derives from the Latin word lux, meaning “light.” Once given to girls born at dawn, Lucy is also associated with Saint Lucia, the patron saint of the blind.
 
Lucy has a wide range of namesakes, from the bossy friend in the Peanuts comic, to psychedelic "Lucy in the Sky with Diamonds," to the rash and zany heroine of I Love Lucy. 
 
It is a name with a rich literary history, chosen for the heroines of Charlotte Brontë’s novel Villette, E.M. Forster’s A Room With A View, Jamaica Kincaid’s Lucy, and C. S Lewis’s The Chronicles of Narnia - just to name a few. 
 
Beyond fiction, Lucy Stone was an important American activist, Lucy Worsley is a successful author and historian, and Lucy Lui is an actress who has imparted strength and style to the name.
 
Simple but sophisticated, playful but grounded, it is no wonder Lucy is a popular choice. Given to over 4000 girls in the US each year, it is a classic that doesn’t feel dusty.
 
If you love Lucy, but don’t love its popularity, you could consider one of its many variants. From vintage Lucille, to the musical Lucetta, to the fresh, unexpected Lux; from nickname-y Lou to sleek Luciana, there are plenty of possibilities.

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>.

Lydia is one of the first place names, after an area of Asia Minor whose inhabitants are credited with strong musical talent great wealth. Always among the US Top 1000 girl names, Lydia is a quietly fashionable classic.
 Although mentioned in the New Testament (Lydia was the first European convert of Saint Paul), it didn't really emerge as a viable first name until the eighteenth century, promoted via the character of Lydia Languish in Sheridan's popular 1775 play The Rivals, and the youngest of the Bennett girls in Pride and Prejudice.
 Lydia continued to be a literary favorite, found in the novels of George Eliot and D. H. Lawrence. And there's also the iconic Groucho Marx ditty: "Lydia the Tattooed Lady."
 Lydia is increasingly appreciated for its history and haunting quality. Cute nickname: Liddy or Lydie.

 There is a Princess Mabel in the Netherlands today, born a commoner and the widow of Prince Friso. Several celebrities have named their daughters Mabel, including Chad Lowe, Nenah Cherry, Bruce Willis and Dermot Mulroney., and the baby on the sitcom Mad About You (in which Mabel was an acronym for Mothers Always Bring Extra Love--a nice thought).

Shirley Temple almost single-handedly lifted the gloom of the Great Depression, and in tribute (and perhaps wishing for a similarly curly-headed, dimpled darling of their own), thousands of parents of that generation gave their little girls her name. In 1935, Shirley was the second most popular girls' name in the country with more than 42,000 babies named Shirley.

 In an earlier time Shirley was used primarily for boys, but the tide turned with the publication of Charlotte Bronte's novel Shirley in 1849, the story of a character whose parents had selected the name for a boy child, then decided to use it anyway when he turned out to be a she.

 In addition to Shirley Temple, there have been Shirleys MacLaine and Jones and writer Shirley Jackson, as well as rocker Shirley Manson.
