From the Stars

The name of the great Renaissance astronomer and mathematician would make a distinctive hero-middle-name for the son of parents involved in those fields.

After Leo, this is one of the most usable names in the zodiac: part ancient, part new-age, part high-tech. In the night sky, the constellation Gemini is present all year round in both hemispheres. It has been associated with twins since ancient times, and its two brightest stars are named Castor and Pollux after the twins of Greek mythology. It also has STEM connections: Project Gemini was a NASA spaceflight program before Apollo.

Gulliver is an obscure Gaelic surname known almost solely through its literary Travels until actor Gary Oldman used it for his son, instantly transforming it into a lively option. British actors Damian Lewis, of Homeland, and Helen McCrory also have a son named Gulliver.

Hadley, most famous as the name of Ernest Hemingway's first wife, is more sophisticated, professional, and modern than cousins Harley, Haley, or Hayden. The hit book The Paris Wife, a novel by Paula McLain told from the point of view of Hadley Hemingway (born Elizabeth Hadley Richardson), has helped popularize the name, which also appears on the vampire show True Blood. Hadley could become this generation's Hailey. Adley, a mashup of Hadley and Addie, has also appeared on the scene.

The Halley version of this popular name family hit the Top 1000 only once, in 1986, inspired by Halley's Comet, named for astronomer Edmund Halley.

The name of the young Greek sun god, brother to the moon goddess Selene, who rode across the sky each day in a chariot pulled by four horses.

Hesperus or Hesperos is a figure in Greek mythology who is the personification of the Evening Star or Venus, the son of the dawn goddess Eos. There's a Longfellow poem about a tragic shipping voyage called The Wreck of the Hesperus. An archaic name that with the revival of many old mythological names might just have a chance at revival.

Hidalgo is the name of a minor planet, and, on Earth, the Spanish word for a nobleman, but we don't see much crossover potential.

Short for Brunhilda, the operatic Valkyrie of Teutonic legend, Hilda still has not quite shaken off that image that image. Though with the resurgence of Matilda, she might just have a bit of a comeback.

Possible middle name for devotees of detective Sherlock.

In Greek mythology, Hyperion is one of the twelve Titans: children of Gaia (Earth) and Uranus (Sky). Hyperion presides over heavenly light, and is the father of Helios (Sun), Selene (Moon), and Eos (Dawn).

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.

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.

Jupiter's partner Juno has entered the mainstream, so it's possible that her divine mate could follow. But not necessarily for boys — Jupiter is currently mostly female in the US, thanks to its similarity to Juniper. Stars including Ed Sheeran and Ashley Tisdale recently welcomed daughters named Jupiter, which could shift the balance even more towards the girls.

Kaiser, as in roll and Wilhelm, appeared for the first time on the US Top 1000 in 2017. It fits the two-syllable -er ending style that's all the rage, and it lends itself to the short form Kai. But we hope this Germanic version of what is essentially a title rather than a name doesn't keep rising on the charts.
