Caesar, the name of the greatest Roman of them all, is rarely used outside Latino families, where the Cesar spelling is preferred —as in activist Chavez and Dog Whisperer Millan. Its original meaning is debated — either "long-haired", "blue-gray" (as in eyes), or "cut" (because Julius Caesar was supposedly born by cesarian section) — it came to be the title to denote all Roman emperors and it is from the name Caesar that many other European royal titles are derived, including Kaiser and Tsar.
 In antebellum America, Caesar became a common name among enslaved people, along with such other classical appellations as Cato and Octavius.

Caesar

Another of the new Greek-accented Cal- names. 

Calantha

If you love Calliope and Callista, you'll love Calanthe, which combines the trendiness of the Greek 'cal' names with the equally fashionable "the" ending (like Xanthe and Evanthe) and a connection to the beautiful Christmas Orchid. Color Calantha one of the more unusual and captivating <a href="https://nameberry.com/list/412/christmas-baby-names">names for Christmas babies</a>.

Calanthe

Spelled with either one 'l' or two, Calista came to the fore in 1997 when Calista Flockhart hit it big as Ally McBeal. Flockhart, who bears her mother's middle name, didn't just introduce a name, she introduced a whole sensibility. Pretty and delicate, Calista is definitely worthy of consideration, especially for parents with Greek roots. 
 In ancient myth, Calista (or Calisto)was a nymph loved by Zeus, whose jealous wife Hera turned her into a bear.

Calista

Callum, a charming Scottish name high on the list in England, Scotland and Northern Ireland, is rising through the ranks in the US now too. And it comes complete with the easy nickname Cal. Kyle MacLachlan chose Callum for his son. Callum might also be spelled Calum; in Ireland, the name became Colm, and in Scotland it's sometimes used as a pet form of Malcolm.
 
Callum was derived from Latin Columba, a unisex given name meaning "dove." Callum was popular among early Christians because the dove was a symbol of purity, peace and the Holy Spirit. St. Columba was one of the most influential of the early Celtic saints.

Callum

Calvin is a slightly quirky but cozy name that has a fashion edge thanks to Calvin Klein. It has been steadily on the popularity list since records were kept, never lower than Number 250, peaking in the 1920s, the era of the Calvin (originally John Calvin ) Coolidge presidency. 
 The name came into use as a first name in honor of John Calvin--born Jehan Cauvin-- the seventeenth century French Protestant reformer whose strict doctrines became the basis of Calvinism, and the name was taken up as a tribute to him.
 Other associations include the above-mentioned Calvin Klein (and his famous 'Calvins' ads), humorous writer Calvin Trillin, the comic strip "Calvin & Hobbes" --and it's also the birth name of Snoop Dog. Calvin O'Keefe is one of the main characters in Madeleine L'Engle's A Wrinkle in Time.

Calvin

Carmelita is an obscure short form of an obscure name that may rise to new prominence during the 2012 Olympics, via runner Carmelita Jeter aka "The World's Fastest Woman."  Carmelita has a particularly international flavor with the original Carmel a Hebrew name long popular in Ireland, with Carmelita itself most popular in Latin countries.

Carmelita

Carmen has long been associated with the sensuous, tragic heroine of Bizet's opera, based on a novel by Prosper Merimee; more recently it has called to mind two other bombshells: Carmen Miranda (born Maria) and Carmen Electra (born Tara), as well as the great jazz singer Carmen McRae. In the celebrity baby name world, this classic <a href="https://nameberry.com/baby-names/495/spanish-names-for-girls">Spanish name for girls</a> was used by Hilaria and Alec Baldwin for their daughter.
 She has plenty of childhood references as well: Carmen Elizabeth Juanita Echo Sky Brava Cortez is a character from the Spy Kids trilogy, Carmen Lowell appears in the Sisterhood of the Traveling Pants series, Carmen de la Pica Morales was a character on The L Word, and Carmen Sandiego is the clever anti-hero in the Where in the World Is Carmen Sandiego? computer-game franchise—she was named for Carmen Miranda and the city of San Diego.
 In the Latin community, Carmen is also used as a <a href="https://nameberry.com/boys-names">boys’ name</a>.

Carmen

Languid, romantic, and classy, this variation heats up Caroline and modernizes Carol, adding a southern accent.
 Pronounced Caro-LINE-a in English-speaking countries, it is heard as Caro-LEEN-a in Italian, Spanish and Portuguese. Nicknames can include Caro and Lina, as well as Carrie.
 A prominent bearer is Venezuelan fashion designer Carolina Herrera (born Maria Carolina), who has designed clothes for First Ladies from Jacqueline Kennedy to Michele Obama. A hauntingly melodic theme song in James Taylor's 'Carolina on My Mind.'

Carolina

Carter has ranked in the Top 100 since the the turn of the millennium, but despite its recent popularity, it's not a trendy new name. In fact, Carter is one of those names that just misses ranking in the US Top 1000 for its entire 140+ year history. 
 
Carter's off its recent popularity peak now, but it's getting some fresh style via Beyonce's country album Cowboy Carter, which references the surname of her husband Jay-Z aka Shawn Carter.
 
Having hot characters named Carter on both Gossip Girl and The OC probably didn't hurt Carter's rise, along with Noah Wyle's Dr. John Carter on ER, who was always called by his last name. Carter also, of course, has presidential cred.
 Carter is especially popular in the Midwest, having recently been Number 2 in Nebraska and Number 3 in Iowa, as well as spreading north to Canadian provinces Saskatchewan (recently Number 2) and Manitoba (recently Number 5). It does straddle the line between country and city, another reason for its longtime appeal.

Carter

Casimer

This ancient name, also spelled Caspar, is finally shedding its ghostly image and moving into the 21st century. Popular in the Netherlands and Scandinavia, where it's sometimes shortened to Cas, Casper could ride the style coattails of cousin Jasper.
Casper was one of the Three Magi who brought gifts to the infant Jesus along with Melchior and Balthasar.
 Some notable Caspers are one-time Secretary of Defense Casper Weinberger (called Cap) and actor Casper Van Dien, whose son is Casper Robert Van Dien III. Claudia Schiffer and Jenny Frost both used the names for their boys, while Jason Lee did a gender switch when he called his daughter Casper (sister of Pilot Inspektor).
 Casper Goodwood was the persistent suitor of the main character, Isabel Archer, in Henry James's novel A Portrait of a Lady.

Casper

Cassia is related to the cassia tree, which has yellow flowers and produces a spice that can be a substitute for cinnamon. Keziah, the name of Job’s daughter in the Old Testament, derives from the name of the plant as well. Cassia also has ties to the Ancient Roman name Cassius, an Ancient Roman family name meaning "hollow." 
 
Cassia is one of the rare names that's truly unusual yet has a stylish feel. Cassia has the added attraction of the sweet smell of cinnamon, thanks to its botanical associations. We predict Cassia will become much more popular along with her brother names Cassian and Cassius. 
 
Keziah, the Biblical equivalent, is also due for rediscovery, while Kassia is the Greek spelling that ties the name to Saint Kassiani, a feminist heroine.

Cassia

Once a powerful Roman clan name, Cecil has lost much of its potency over the years, though it retains a strong presence in the sports and jazz worlds. Past bearers include film giant Cecil B. DeMille, poet Cecil Day Lewis, father of Daniel, and photographer Cecil Beaton. Fictional Cecils appear in Oscar Wilde's play, Lady Windemere's Fan, E. M. Foster's A Room With a View and the film Lee Daniel's The Butler.

Cecil

Cedric was invented by Sir Walter Scott for the noble character of the hero's father in Ivanhoe, presumed to be an altered form of the Saxon name Cerdic. The name was later also given to Little Lord Fauntleroy, the long-haired, velvet-suited, and lace-collared boy hero of the Frances Hodgson Burnett book, who became an unwitting symbol of the pampered mama's boy.
 Since then that stereotype has been broken principally by the handsome Harry Potter character Cedric Diggory, played by the teen-aged pre-Twilight Robert Pattinson, and it, like cousin Cecil, is at the point of being rediscovered by cutting-edge namers.
 Actor and comedian Cedric the Entertainer has propelled this name into the spotlight in recent years.
 Cedric has been on and off the charts the last few years, but is currently back in the Top 1000 in 2022.

Cedric

Celeste is a softly pretty and somewhat quaint name with heavenly overtones, which kids might associate with Queen Celeste of Babar's elephant kingdom. She's a light and lovely choice that's finally getting noticed.
 Celeste has been in the Top 1000 every year since 1880. Best known modern Celeste is Oscar-winning actress Celeste Holm.
 If you want a more unusual variation, consider Celestine, Celestia -- or even Celestial.

Celeste

Celestine is a pretty, crystalline extension (actually a diminutive) of Celeste that would make a choice that is both delicate and strong. It is also a popular name in France.
 Celestine was the name of painter Edgar Degas's Creole mother. Some people might associate it with the 1993 spiritual novel "The Celestine Prophecy."
 Celestina is another attractive version.

Celestine

Chalmer

Charlene is a Charlotte variation that, along with similar names like Arlene and Marlene, spiked in popularity in the 1940s and fifties, reaching a high of Number 100 in 1949. Most parents today would prefer one of the note classic versions -- or even nickname Charlie.

Charlene

Chester is a comfortable, little-used teddy-bear of a name that suddenly sounds both quirky and cuddly.
 Chester was a Top 100 name in the US from the 1880s to 1929, gradually fading till it finally dropped off the list completely in 1995. But it's popular now in England and Wales, where it ranks in the Top 100

Chester has been seen on old TV shows like Gunsmoke and The Life of Riley, then reappeared later on The Nanny and The Wire. Chester Alan Arthur made it presidential, it was a World War II hero via Admiral Chester Nimitz, the comic world associates it with Chester Gould, creator of Dick Tracy, and it has modern musical ties to Chester Bennington, lead singer of Linkin Park.
 Tom Hanks and Rita Wilson have a son named Chester.
 Nickname Chet has, like Hank, a friendly retro vibe.

Chester

Clairette

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. It now ranks right around Number 100, making it a modern classic that's neither too popular nor unfamiliar.
 
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

The name of the guardian angel in It's a Wonderful Life is rarely heard the rest of the year because of its studious, near-nerdy image, but this could change in the current naming climate. 
 An English peerage title, Clarence enjoyed great popularity at the turn of the last century, reaching as high as Number 18 in 1900, and staying on the list until 2010. It has two prominent legal bearers--Clarence Darrow, defense attorney at the Scopes Trial, and current Supreme Court Justice Clarence Thomas. We can thank Clarence Birdseye for the invention of frozen food. Aretha Franklin and Louis Armstrong both named their sons Clarence.

Clarence

Claribel improves on its mother name Clarabelle by distancing itself from the clown and the cow.

Claribel

Clarissa, the daintier version of Claire, has a long literary history of its own, having been featured in the novels of Samuel Richardson, Charles Dickens, and Virginia Woolf—Clarissa was the title character of Mrs. Dalloway—not to mention the 1990s teen sitcom, Clarissa Explains it All. 
 Clarissa is a name definitely worth considering as an alternative to the overused Vanessa and Melissa. Appealing diminutives are Clarry and Claris.
 Red Cross founder Clara Barton was born Clarissa.

Clarissa

Clark seemed to have been Gone with the Wind, but parents looking for a short, strong boy's name are now beginning to appreciate its cool combination of Gable charm with Superman power. 
 Clark has been steadily on the popularity list—it was Number 176 in 1881 and well used in the 1940s and 50s, and is now on another upswing.
 Long-term Hollywood heartthrob Clark Gable was born William Clark—his middle name was the maiden name of his maternal grandmother.

Clark

Claude is a soft-spoken French name that conjures up the pastel colors of Monet and harmonies of Debussy. In France, it is used for girls as well, in fact in the Tracy Chevalier novel Lady and the Unicorn, the protagonist is a female Claude.
 Claudes have appeared in such iconic movies as Chinatown and Close Encounters of the Third Kind. Actor Simon Baker has a son named Claude Blue.
 A French classic, Claude was also a top 100 name in the U.S. until 1922.
 The attractive Italian version Claudio is occasionally heard in this country, and Claudius is the original Latin--which could be restored in the current Latin-loving climate. While "lame" is the most widely-acknowledged meaning, some etymologists theorize that the name may relate to the word for enclosure or clause, an alternate meaning that may appeal to a child with a form of this otherwise-appealing name.

Claude

Once seen as a dated French Claudette-Colbert feminization, along with Annette and Paulette, we can see Claudette moving into a more plausible Colette-Cosette arena. While some may be put off by the common "lame" meaning, some etymologists theorize that the name may relate to the word for enclosure or clause, an alternate meaning that may appeal to a child with a form of this otherwise-appealing name.

Claudette

Claudie

Almost fits into the wildly popular Jaden-Caden-Braden family -- but not quite; a possibility for parents who want a similar but more traditional name. 

In fact, Clayton has a much more august name history than you might guess, ranking among the US Top 1000 names for baby boys for the entire history of the Social Security list, since 1880. It's now at its lowest point ever, but still makes the Top 300.

Clayton can also be thought of as a place name, with a meaning that can be translated as "clay town," a sibling of Payton. Clay is an attractive short firm.

Clayton

This surname related to Clement is strongly associated with Major League pitcher Roger Clemens, winner of more Cy Young awards than any other pitcher in baseball history, and has a softer sound than Clement. Some variations are Clemen, Clementio, Clemention, and Clemons.

Clemens

Clement, the name of fourteen popes and several saints, has a pleasantly, positive, slightly antiquated feel, like the phrase "clement weather." 
 Clement C. Moore wrote the poem "A Visit from St. Nicholas," Clement Attlee was a prominent post-World War II British Prime Minister, and Clement Greenberg was the art critic who promoted Abstract Expressionism.
 The hero of Thomas Hardy's The Return of the Native is Clement Yeobright, known as Clym rather than the usual Clem.

Clement

Clementine is a Nameberry favorite that broke back into the US Top 1000 in 2014 after more than half a century off the list. 
 A female variation of the more-unusual Clement, Clementine's meaning suggests peace and happiness, a lovely image. Other girls' names with similar meanings include Beatrice, Felicity, Hilary, Arcadia, Irina, and Mercy.
 If "Oh, My Darlin'" still rings too loudly in your ears, consider pronouncing Clementine as Clementeen—or even using Clementina, which rhymes with Christina. Stylish Claudia Schiffer chose Clementine for her daughter, as did Ethan Hawke and Rachel Griffiths. 
 Kate Winslet played a character named Clementine in Eternal Sunshine of the Spotless Mind. And for a kid reference—there's a Muppet named Clementine.

Clementine

Cleora is a now-extinct name (there were no babies named Cleora recorded in the U.S. in 2012) that achieved some standing in the early 20th century thanks to the craze for all things Egypt-related.  A range of Cleopatra diminutives, including Cleo, Cleora, Cleona, and Cleola, made the Top 1000 then as the ancient tombs were opened in Egypt.

Cleora

Cliff is a familiar, timeless short form -- never too popular, yet widely known -- that you might also think of as a geographical name ala Vale or Field.

Cliff

Clint

Even though in the past Clyde may have been identified as half of the infamous outlaw duo with partner Bonnie Parker—especially after the 1967 movie in which he was played by Warren Beatty—Clyde has always had an element of jazzy cool that could overcome all the rest.
 The name relates to the River Clyde that runs through Glasgow, Scotland. It was a Top 100 name in the US through the 1930s, and has made a comeback in the last few years, reentering the Top 1000 in 2013.
 Clyde Griffiths was the doomed protaganist of Theodore Dreiser's 1925 novel An American Tragedy. In the field of sports, basketball Hall of Famer—and later Dancing With the Stars participant—Clyde Drexler was known as Clyde the Glide, and Walt Frazier's nickname was Clyde. Catherine Keener and Dermot Mulroney have a son named Clyde.

Clyde

Like the French author with whom the name is most closely associated, Colette is a chic and charming name that is being rediscovered. After disappearing for nearly 30 years, Colette rejoined the Top 1000 in 2012 at Number 659 and has continued to rise since then. Dylan McDermott used it for his daughter, as did actress Constance Zimmer.
 There is an appealing animated Colette featured in the film Ratatouille.

Colette

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

First used during the Victorian craze for jewel names; it could rise again, along with Ruby and Pearl, though it doesn't have as much luster. 

Coral

Cordelia is exactly the kind of old-fashioned, grown-up name for girls that many parents are seeking for their daughters today. The name of King Lear's one sympathetic daughter, Cordelia has both style and substance along with its Shakespearean pedigree.
 <br/
Cordelia is a Nameberry favorite—Number 106 on the site—and it reentered the US Top 1000 in 2014 after a 60+ year absence. By 2016 it sank below that line again, must to the relief of many Cordelia fans who feared the name would get too popular.
 
If you're torn between Cordelia and the equally lovely Cora, you can always choose Cordelia for long and then call her Cora for short—or Delia, Lia, Del, or even the extremely different Cordie.
 Cordelia also appeared in Evelyn Waugh's Brideshead Revisited, Margaret Atwood's Cat's Eye, as detective Cordelia Gray in P.D. James's mystery novels, and was promoted by a character on both Buffy the Vampire Slayer and its spin-off Angel.
 And then there's that quote from the heroine of Anne of Green Gables: "I would love to be called Cordelia. It's such a perfectly elegant name."

Cordelia

Cordie

Corene

Cormorant is definitely one of the most unusual of the newly fashionable animal names, and one of the rare bird names for boys. 

Cormorant

In ancient Rome, Cornelia was considered the paragon of womanly virtue, making it a handsome name with an excellent pedigree. It's rare today, so if you want a name no one else is using, somewhat reminiscent of Amelia and the Shakespearean Cordelia, Cornelia should be on your list. Cornelia's short forms might include Cora, Nelia or Nell--anything but Corny.
 The name of the mother of famous second century Roman reformers, Cornelia emerged in England in the seventeenth century, probably brought in by Dutch immigrants. The painter Jan Vermeer had a daughter named Cornelia.
 Cornelia has not made a mark on the U.S. popularity list since 1965--so she's more than due for reconsideration. In the meantime, it's been associated with contemporary socialite Cornelia Guest, giving the name an elite image.

Cornelia

This name has not one but two impressive cultural connections: collage artist Joseph Cornell and photographer Cornell Capa--not to mention Cornell University.

Cornell

A common surname in Scotland, but a starchy first name choice. 

Crawford

From Haruki Murakami's Kafka on the Shore, the story of a boy named Kafka -- crow in Czech.

Crow

Lovely entry into the tree name genre, joining Maple, Pine, Oak, and Willow.

Cypress
