Hadley, an old surname-name best known as the name of author Ernest Hemingway's "Paris Wife," only recently broke onto the scene in a big way. While Hadley has considerable appeal, spelling variations such as Hadleigh—and onward to Hadleah, Hadleah, Hadli and so on—only emphasize its trendiness. Hadleigh made its first appearance on the US Top 1000 in 2014.

Halia is one of Hawaii's top baby names, in the Top 50 for girls in 2021. But it's rare outside its native Hawaii, given to only 57 baby girls in the US last year.

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.

You might think of Harper as the hottest name of the last decade, jumping from obscurity to the Top 10, where it remained until last year.

In the USA, Hattie is one of those nicknames that is now more popular than its parent name, Harriet. In England, however, Harriet is still by far more popular than Hattie, while in Australia, Harriet is highly popular while no data exists on Hattie. In the US, we’d like to see Harriet get more usage but we’re happy to see Hattie again.

A newly successful name for girls, which, like Brayden and Caden, used to be strictly for the boys. Young Heroes and now Nashville star Hayden Panettiere planted it in the girls' camp.

Helena is one of those classic names that just misses making the US Top 1000 girl names for its entire history, falling off for a single year in 1992. Since then it's been drifting lazily up the charts, and makes a perfect choice if you want a name that both fits in and stands out.

The feminine form of Helios or Helio is occasionally heard in Spain and Portugal. In Greek mythology, Helia is one of the Heliades, daughters of the sun god Helios by Clymene the Oceanid.

Though we've gotten used to Hermione via Harry Potter, and even Hermes with its godlike and fashion associations, most people would still have a problem with Hermia (too close to hernia?) and Herman.

Hermione's costarring role in Harry Potter has made this previously ignored, once stodgy name suddenly viable. Hermione could really take off once today's children start having kids of their own.

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 disgraced heroine of The Scarlet Letter's name, after long neglect, just might have a chance at revival, following in the wake of sister-name Esther. We've characterized her elsewhere as an eccentric aristocrat, much more accepted in the U.K. than she has been here.

Holland is one of the coolest geographical names, unadorned and elegant, evocative of fine Rembrandt portraits and fields of pink and yellow tulips. It first entered the US Top 1000 in 2014.

Hollis is a surname-name used quietly for both genders. At last count, it was given to over 200 baby boys and 160 baby girls in the US. Now a Top 1000 name for boys, it could well break into the charts for girls too in the coming years.

This surname gained momentum in the 1990s, when it was particularly in vogue for males. However, it seems to be experiencing a surge for females—it was one of the fastest-rising names of 2013, jumping 266 spots back into the Top 1000.

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.

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.
