Freya has long been popular in the U.K. but has only taken off in the US in the last decade, along with the entire category of mythological names. Derived from the Old Norse name Freyja, meaning "Lady, noble woman", Freya is the name of the Norse goddess of love, beauty, and fertility.

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 at Number 78, making it a modern classic that's neither too popular nor unfamiliar.

Olivia, a lovely Shakespearean name with an admirable balance of strength and femininity, is the Number 1 name for baby girls in the US and one of the top girls' names around the world.

Alice is a classic literary name that's both strong and sweet, ranking in the US Top 100 and popular throughout the Western world.

A beautiful modern Cornish nature name that is rapidly picking up steam in the States: even spawning variant spellings like Elowyn and Elowynn. In its native region, it wasn't widely used as a name before the twentieth century, when the Cornish language was revived. A fresh and magical member of the fashionable El- family of names, it has a pleasant, evocative sound.

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.

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.

The goddess name Aurora has consistently been on the US popularity list since the nineteenth century, but has really taken off in the past 30 years.

Adelaide is now heading straight uphill on the coattails of such newly popular sisters as Ava, Ada, and Audrey, and in the company of Adeline and Amelia. It was chosen by actress Katherine Heigl for the name of her second daughter.

Melodic and beautiful but with a touch of sass, Calliope is the name of the muse of epic poetry — and perhaps less glamorously, the musical instrument on the merry-go-round. Bold and creative, it debuted in the US Top 1000 in 2016, and in more recent year, IT appeared in the Top 500.

Also spelled as Kalliope — the more traditional Greek transliteration — Calliope means "beautiful voice", making this a musical and poetic choice. It was rarely heard in the US until the 2000s when Calliope "Callie" Torres from the show Grey's Anatomy helped introduce it to a wider audience.

Though never as popular as the name of her Bewitched mother, Samantha, Tabitha has its own quirky, magical charm.
