Cadia

Caelyn

Cute but slight mix of stylish sounds Cam and Bree, chosen by Rick Schroder for his daughter. 

Cambrie

An interesting and unusual choice, with a choral feel. 

Cantara

Carina is a pretty delicately feminine name whose fall from popularity is not helped by its similarity to hurricane name Katrina or slang victim Karen.

Carina

Carine

Carlotta has a large measure of finger-snapping charm and substance — despite being a not too pleasant character in The Little Mermaid. Carlotta is also the diva/prima donna in The Phantom of the Opera, and there was an Empress Carlotta of Mexico.
 Carlotta (spelled with one 'T' in Spanish), has not been heard much since the 1960s — which might add to its appeal to someone looking for a more international spin on Charlotte.

Carlotta

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

The rarely heard feminine version of the saint's name Cassian, this name is elegant and somewhat frilly, but holds the possibility of more straightforward nicknames like Cass, Cassie or Ana. With the rise of the whole group of names for both genders starting with the Cass sound, Cassiana has the potential to become one of the more visible <a href="https://nameberry.com/search/girls-names/c">girl names starting with C</a>.

Cassiana

Though not much in use, still retains a cozy Little House on the Prairie-type pioneer feel. 

Cassie

Feels like a hybrid of Celia and Belinda, but Celinda is also a Spanish botanical name for the sweet mock orange.

Celinda

Cerelia is a melodic and unusual choice, perfect for a child born in April or May. Another version is Cerella.

Cerella

Cerena

Lovely, international, tea-scented possibility undiscovered by baby names.
 
Ceylon may ultimately be derived from the Sanskrit siṃhala, meaning "island of lions" or "abundance of lions."

Chelsea was last fashionable around the time First Daughter Chelsea Clinton was born, ranking in the Top 25 in the early 1990s.

Chelsey never hit the heights of the original. About 40 baby girls were named Chelsey in the US last year, and about ten times that many called Chelsea.

Christina, a pretty and feminine, crystal clear classic, may be trending downward, but it's never out of style. Christina's short forms Chris, Christie, and Tina all seem dated—making the royal Christina best used in its full glory. 
 Christina became a royal name in Sweden (Greta Garbo played Queen Christina in one of her classic films) and Spain, and it is more usable today than the French Christine.
 Christina is now well represented by actresses Applegate, Ricci, and Mad Men's Hendricks, alongside singer Aguilera and Orphan Train novelist Baker Kline. Previous bearers include British poet Christina Rossetti and Australian novelist Christina Stead.
 Christiana is a more distinctive variation.

Christina

What's Cia short for? Cynthia or most any other C-name. Stylish in its sleek Mia-Nia minimalist feel, but may remind some of the Central Intelligence Agency.

Cindy as a name in its own right made it into the Top 20 in 1957 and remained a Top 200 girls' name until the end of the 20th century. Although it's fallen precipitously since then and left the Top 1000 completely in 2015, Cindy remains a name commonly heard in the US. Today, though, it would more likely be attached to moms or grandmas than to babies. 

Whether as a short form or a nickname used on its own, Cindy along with other popular nickname-names of its era -- Debbie, Kathy, Judy -- has faded from fashion to be replaced by the stylish nickname-names of this era, such as Ellie and Charlie.

Cindy

An attractive and unusual name that may be a variation of Cleo, Clea was possibly invented by Lawrence Durrell for a character in his Alexandria Quartet.
 Actress Clea DuVall is one noted bearer of the name, another is Paul Newman and Joanne Woodward's youngest daughter, who was named Claire Olivia, but always called Clea.

Clea

Strongly feminine variation of Colby with two prime associations: singer Colbie Caillat and actress Colbie Smulders (born Jacoba).

Colbie

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

Colinda

Midcentury Irish-American favorite, never used in Ireland itself, being the generic word for "girl"; rarely given today. 

Colleen

Coraline may not be original to Neil Gaiman's wonderful book of the same name, but it might as well be. Gaiman's young heroine Coraline Jones is constantly called Caroline but as a name Coraline is more distinctive and has a more mysterious feel. The 2002 novel Coraline was made into a 2009 animated film voiced by Dakota Fanning and nominated for an Academy Award. The number of baby girls named Caroline increased by a factor of 100 between 2007 and 2017 -- going from 5 to over 500 in a decade.

Coraline

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.

Crimson

Cyane is a mythological Sicilian nymph who lived in a pool and whose name is an intriguing twist on the color name trend.
