Agatha Christie's Poirot

Guido was very popular in Renaissance Italy, with many namesakes including painter Fra Angelico (born Guido di Pietro) and mathematician Guido Fubini. Guy Fawkes, of gunpowder plot fame, sometimes used this version. Nowadays it's unfairly overlooked, but in the current trend for snappy international names ending in -o, this cultured gem deserves more use.

The patron saint of comedians and dancers (also known as St Vitus) has a name that is both the ultimate everyman, and has a hint of British aristocracy. In the States, Guy was most popular in the 1950s. Now he hovers steadily below the Top 1000, in the sweet spot of familiar but not overused. With the meteoric rise of Kai, Guy may have potential with parents looking for a more classic name with a similar sound.

The name of the last Anglo-Saxon king of England before the Norman conquest, and a name that's long been associated with a pipe-smoking, bespectacled grandpa or uncle.

Harriet has long been considered a stylish, upscale name in England, but it's still waiting to be revived in the US—though some parents seeking a solid, serious semi-classic are beginning to consider it.

On the staff of a manor house.

Harry is the medieval English form of Henry, which derived from the Germanic name Heimrich, meaning "estate ruler." Harry was the nickname of all eight King Henrys; it is also a diminutive of Harold and Harrison.

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.

Previously used primarily by Latino families, this name of the great hero of the Trojan War as related in Homer's Iliad is beginning to be considered more seriously by others seeking noble ancient hero names as well--it was also the name of the knight who raised King Arthur as his own son.

Helen is a name that has connoted beauty since ancient times – Helen of Troy was the the mythological "face that launched a thousand ships," over whom the ten-year Trojan War was fought.

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.

Despite a return to such feminizations of male names as Josephine, Clementine, and Theodora, starchy Henrietta has not made it into that group. Still, if you look hard enough, you'll see that Henrietta has the same vintage charm.

Henry is back. The classic Henry climbed back onto the Top 10 in the US in 2021 for the first time in over a century, and now stands at Number 8.

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.

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.

French form of Hildegard

This is an eighteenth century elaboration of Honor found in Charles Dickens (Bleak House) but rarely heard here and now.

The ancient name Horace sounds fustily fuddy-duddy, and yet, with the resurrection of Homer, and the new interest in old Roman names...who knows.

Howard, once hugely popular -- in the Top 50 from the 1870s to early 1950s, hitting Number 24 in 1920 -- has been stuck in Dad-Grandad limbo for decades, but is showing some signs of stirring back to life. Along with such formerly-fusty names as George and Harold, Howard may soon feel baby-appropriate, perhaps with the short form Ward.
