Classic and elegant but with boyish charm, Theodore has become hit name in recent years, vaulting into the US Top 10 in 2021 for the first time ever and into the Top 5 in 2024. A favorite in English speaking countries, it also ranks highly across the UK and Ireland, and in Canada, New Zealand, and Australia.

An aristocratic and stately Germanic route to the popular Leo, Leopold is a royal name: Queen Victoria used it to honor a favorite uncle, King Leopold I of Belgium. These days, this royal tie may be seen as a drawback to the name, owing to the cruelty of King Leopold II's rule over the Congo, though it remains popular in Austria, Poland, and France (as Léopold).

Cornelius, the New Testament name of a third century Pope and saint, is one of those venerable Latin names on the edge of consideration, despite the corny nickname alert.

For centuries, this name had a romantic, windswept image due to its strong connection to the poet Lord Byron, who inspired its use as a first name. It is one of those surprise names that's appeared on the Top 1000 every year since 1880.

Ernest is one of those sober, so-far-out-they're-beginning-to-be-reconsidered Great Uncle names. Ernest recently received a big style boost when Britain's Princess Eugenie chose it for her second son.

This image of this distinguished Anglo-Scottish surname, drawn from the French place name of the ancient castle of Saint Foi de Montgomery, is rapidly shifting from fusty and formal to cool. And dashing short form Monty (or Monte) nudges it to cute.

Casimir, a traditional name of Polish kings, could do quite well these days as we see the rise of Caspian, Cassius, Castiel, et. al. Like Leopold and Laszlo, Casimir is strong and worth considering if you've got an adventurous streak — and bet your son will too.

The name of an important ancient Roman emperor, Tiberius might sound a bit heavy for a modern boy to carry, but with the rise of Atticus, Tiberius and brothers begin to feel more baby-friendly, much in the same way as Old Testament names like Elijah and Isaiah have been rejuvenated.

In ancient Rome, Cornelia was considered the paragon of womanly virtue, making it a handsome name with an excellent pedigree. It's rare today, so if you want a name no one else is using, somewhat reminiscent of Amelia and the Shakespearean Cordelia, Cornelia should be on your list. Cornelia's short forms might include Cora, Nelia or Nell--anything but Corny.

Could be a novel way for a boy's name to honor an ancestral Claire.

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.

Last in fashion in the 1930s, Bertram might once have been firmly in the best left in the past category, but with sweet nickname Bertie and the cool option of Bram, Bertram might just be one to reconsider. Fitting in with other clunky vintage options like Chester, Sidney, Abram, Ebenenzer, and Wilfred, Bertram is a literary option, appearing as the full first name of P.G. Wodehouse's inimitable Bertie Wooster and on a character in Shakespeare's All's Well That Ends Well.

Zephyr may not be a name often heard in the U.S., but its variations are used throughout Europe. Zephyrine, a cousin in sound and feel if not in fact to such lovely names as Severine and Seraphina, has distinctive possibilities.

Euro-cool. Heard more in Scotland than in England or the US, Ludovic Lesly is a character in the Sir Walter Scott novel Quentin Durward and Sir Ludovic Kennedy was a noted Scottish broadcaster and writer. Cute nickname: Ludo.

This rarely used New Testament name could make an unusual route to the cool nickname Nico. Borne by the person who helps to entomb Jesus following his crucifixion, it has the powerful meaning of "victory of the people" and is the Latinized form of the Ancient Greek Nikodemos.

Humphrey is an old name that might have faded completely were it not for that Bogie flair. A royal name in Britain, where it's used somewhat more frequently, Humphrey might just have some life beyond Bogart here, especially with the recent interest in the names of Golden Age Hollywood stars. His first name was the maiden name of his mother, Maud Humphrey, a well-known illustrator who used baby H. as a model.

Ferdinand is a traditional name among Spanish royal families and also appears in Shakespeare's The Tempest, borne by the handsome young prince shipwrecked on Prospero's island. Bold, daring, and poetic, it was a popular choice in the US in the 19th and early 20th century, but the 1938 movie Ferdinand the Bull has left it with a lingering clunkiness and it has been out of style since the 80s.

An aromatic, unconventional name.

The sophisticated Edmond and its nearly-identical twin Edmund are coming out of mothballs now that Edward, inspired by Twilight, is once again a hot name. Parents looking for an alternative might gravitate to Edmond, a handsome classic that has both class and style.

Pronounced "TAHL-a-mee," this was the name of one of Alexander the Great's generals and several Greco-Egyptian rulers, as well as the name of a famous Greek astronomer. Actress Gretchen Mol brought it into modern times when she chose it for her baby.
