Girls names that end 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.

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.)

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.

Rio is one of Japan's most popular girls' names, constantly sitting in that country's Top 10. Of course, Rio may also stem from the Portuguese and Spanish word for river, and the Brazilian city Rio de Janeiro. A truly international name for a cosmopolitan baby!

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.

Best known as one of the moons of Jupiter, Callisto was a nymph coveted by Zeus who was turned into a bear by Hera, becoming the Great Bear (Ursa Major) constellation.

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.

Ino was one of the Queens of Thebes who, after her death, became an immortal. Ino raised her nephew, Dionysus (son of Semele and Zeus), provoking the wrath of Hera. In desperation Ino threw herself into the sea and was thereafter venerated as Leucothea (The White Goddess).

This is a Greenlandic girls' name made royal when Prince Frederik and Princess Mary - now King and Queen - named their twin daughter Josephine Sophia Ivalo Mathilda.

Roman statesman's name with a cool and quirky sound. Marcus Tullius Cicero was a Roman scholar, orator and lawyer who had an immense impact on the Latin language.

Dido was the heroine of Virgil's Aeneid and of the opera "Dido and Aeneas," and in Roman mythology the founder of Carthage. A strong ancient name in the Juno mode, but it could have some awkward associations down the line.

Lilo is the name of the spunky little Hawaiian girl character in the Disney movie Lilo & Stitch-- and is also Lindsay Lohan's nickname. Multi-cultural, it can be found in Hawaiian, German and Hebrew nomenclature.

Despite the possibility of gender confusion, the Hero in Greek myth was a woman. Myleene Klass got that when she chose Hero for her daughter, and Sam Taylor-Wood and Aaron Johnson used it as their daughter's middle--and we wouldn't be surprised to see more girls with this heroic name.

The grandiose name of a French revolutionary – in full: Honoré Gabriel Riqueti, comte de Mirabeau. Mirabeau likely derives from Latin mirabilis, making it a masculine cousin of Mirabelle.
