Girls ending in O

Margot is suddenly a star again. After a nearly-half century absence, it hopped back on the Top 1000 list in 2013 and is on the rise. The Margot spelling is now given to three times as many baby girls as the Margo one.

Cleo, one of the few girls' names to boast the cool-yet-lively o ending, is of course short for Cleopatra, the name of one of the most powerful women in history.

Juno is an ancient name that feels as fresh as if it had been minted, well, not yesterday, but in 2007. Since the release of the popular indie film Juno, this lively but strong Roman goddess name has held new potential as a baby name. Currently in the UK Top 500 and used in The Netherlands too, Juno is on the rise in the US - and is 15 times more popular than it was before the release of the film.

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.

Cool meets Born Again meets Brad and Angelina, who made Shiloh an instant star when they chose it for their daughter. While Shiloh has risen from obscurity thanks to its celebrity baby use, it hasn't become a star the way brother names Maddox and Pax have. It entered the Top 1000 in 2007, one year after the birth of Ms. Jolie-Pitt.

Margo and Margot sound exactly the same, so why has the Margot spelling hopped back onto the Top 1000, outpacing Margo in numbers more than two to one? (Over 350 baby girls were named Margot in the most recent year, versus 150 named Margo.)

Meadow's upward popularity trajectory certainly suggests that the name has transcended its connection to The Sopranos.. In the US, more than 750 baby girls were named Meadow last year, a number we expect to keep rising.

Manon is an endearing French pet name for Marie or Marianne; it has the international yet straightforward feel that makes it a viable import. Manon of the Spring was a gorgeous French film, Manon Lescaut a 1731 novel by Abbe Prevost, set in France and Louisiana, that was controversial in its day. It formed the basis of operas by Puccini and Massenet, and several films and TV series.

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.

Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.

Coco came to prominence as the nickname of the legendary French designer Chanel (born Gabrielle) and has lately become a starbaby favorite, initially chosen by Courteney Cox for her daughter Coco Riley in 2004. At first it was the kind of name that the press loves to ridicule, but we predict Coco's heading for more broad acceptance and even popularity.

Yes, it's pronounced with a long o sound at the end, just like Margo and Margot. This spelling was popularized by supermodel, actress, and tragic Hemingway granddaughter Margaux, whose name spelling came courtesy of a bottle of French wine. (The original spelling of her name was Margot; she changed it when she heard her parents were drinking a bottle of Chateau Margaux the night she was conceived.) Margo itself is a diminutive of Margaret, which means "pearl" or, in its French version, "daisy." Margaret or Marguerite would be more stylish variations now.

Echo, the pretty, resonant name of a legendary nymph, was the heroine of Joss Whedon's sci-fi series Dollhouse. Nick Hexum, of the band 311, named his daughter Echo Love.

Marlo first came to prominence as a perky, pretty nickname name that seemed to have been invented by or for Marlo Thomas, who was born Margaret. But Marlow and Marlowe are English surnames meaning driftwood, are more popular forms of the name, giving it historical depth and a nature meaning. And Marlo is the most truly gender-neutral, given to about 100 babies of each sex last year.

Lilou is a charming, rarely heard import. Occitan is a language spoken in Provence, in the south of France, in which the suffix "ou" denotes a pet form — thus, Lilou as a short form of Liliane or its Occitan form Liliana or Liliano. Its popularity in France--where it's currently Number 12--can be traced to the 1997 film The Fifth Element.

This hyper-rhythmic name has two evocative references. In Greek mythology, she was an island nymph, a daughter of Atlas, who delayed Odysseus from returning home. It is also a genre of West Indian music, originating in Trinidad and Tobago and largely popularized in the States by Harry Belafonte.

With Isabel getting so popular, parents are searching for new varieties of the name, and Isabeau is one that makes a lovely French twist.

Io may be one of the slightest names in the book, but there aren't many two-letter names with as much substance as this Greek mythological example. Io, a name used for the largest moon of Jupiter, was in classic myth raped by Zeus and escaped from him by changing herself into a cow.

On trend for boys but with plenty of unisex appeal too, the place name Cairo was put on the map for girls when model Beverly Peele chose it for her daughter. Given to around 50 girls each year, it hasn't caught on just yet but with its similar sounds to Kaia and Skyler, it might do in the future.

Clio is the name of the ancient Greek mythological muse of history and heroic poetry, one that is rich with modern charm and would make an intriguing choice, especially thanks to its dynamic o-ending.
