Imogen has long been fashionable in England and is gaining favor in the US among stylish parents. Pronounced the British way — the initial i is short as in Kim, as is the final E as in Ken — Imogen is as pretty and classy as it is distinctive.

Lachlan is as Scottish as haggis and tartan plaid kilts—a favorite used throughout England, Scotland, Australia, and New Zealand—and just beginning to be noticed in the US: it reached the Top 1000 for the first time in 2013. An ancient name, Lachlan was originally used to describe the Viking invaders of Scotland, those from the land of the lochs.

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.

Lavinia is a charmingly prim and proper Victorian-sounding name which actually dates back to classical mythology, where it was the name of the wife of the Trojan hero Aeneas, who was considered the mother of the Roman people.

Delaney has been a popular surname-style choice since 90s, when it joined other Irish surnames such as Cassidy, Kennedy, and Mallory on the US Charts. Buoyant, bright, and cheerful, it ranks in the US Top 250 and is given to nearly 1300 babies every year.

While theoretically unisex, this surname name has been edging up the girls’ names list, perhaps originally as an Ashley substitute. One quality in Ainsley's favor: It's remained steadily popular -- but not TOO popular -- for more than 20 years now, ranking consistently around Number 400. That makes it stylish and familiar without showing up everywhere.

Calisto is a masculine name derived from Greek mythology, where Callisto was a nymph who was transformed into the constellation Ursa Major. The masculine form shifts the mythological association while maintaining the celestial connection. The name comes from Greek 'kallistos' meaning 'most beautiful.' While the feminine form Callista is more common in English-speaking countries, Calisto offers a distinctive alternative for boys. The name carries an artistic, sophisticated quality with its classical roots and melodic sound. Popular in some Latin cultures, Calisto provides a unique option that balances exotic appeal with historical depth. Its connection to the stars gives it an aspirational, expansive quality that many parents find appealing.

Hurricane is a storm, but it's also an American name, thanks to rising tennis star Hurricane Black -- whose sister's name is Tornado. There's no reason this tempestuous choice can't work for boys too, inasfar as the name can work for any child. As a name, Hurricane is definitely original and attention-getting, but is it a name you'd want to carry around for life?
