Actor Pierce Brosnan brings a strong helping of charm to this name. Pierce was actually a popular name long before Mr. Brosnan came along, from 1880 to the end of the 1930s.

A Top 10 name from the 1880s until the 1920s, Frank has been falling for decades but last year reversed course for the first time in a century, edging up the popularity list a few notches. And Frank still has a certain warm, friendly real-guy grandpa flavor that could come back into style, like other such choices as Jake and Jack.

Cal is a nickname style name that feels as friendly and calm as it does cool and breezy. While its longer forms have proved more popular over the years, Cal as a stand alone has dropped on and off of the US Top 1000 since the 1880s.

The appealingly energetic Dax, with its trendy X-ending, re-entered the Top 1000 in 2007. Its somewhat sci-fi vibe emanates from his appearance as a fictional being in the Star Trek universe, seen on the TV show "Star Trek: Deep Space Nine." The Power Rangers character Dax Lo was the Blue Ranger.

While John Wayne and Duke Ellington are worthy role models, the reason Duke is currently enjoying a revival and returned to the Top 1000 in 2013 as one of the year's fastest-rising boys’ names is more likely due to the name given to high-profile TV couple Giuliana and Bill Rancic. Christened Edward Duke, he has always been called by his middle name, just as Edward Duke Ellington was. Duke is just one of several aristocratic titles being increasingly used by ordinary citizens.

Short and cool with rugged charm, Wes is a rising star in the US, climbing the charts along side Wesley and Weston and joining other one syllable options such as Mack, Jett, Tate, and Brooks. Filmmakers Wes Anderson and Wes Craven lend the name a stylish and creative air, but it also has Old Western undertones thanks to its literal meaning, "west".

Zeke is a casual form of the name Ezekiel, an important prophet from the Old Testament. How well Zeke holds up depends on the boy: it could be a cooler alternative of Zack, or it could prove too close to "geek." Both Zeke and Ezekiel lag behind in popularity on the UK charts.

Flint is one of the new macho names on the rise today, part old-school tough guy, part rebel. You won't find a tougher, steelier-sounding name; it's part of a genre on the rise along with cousins Slate, Stone and Steel.

Now that many dogs are named Max, it's safe to use this sleek, solid, regal name again for your child. And with the charm of its final x, its regal meaning, and its offbeat simplicity, Rex is definitely one to consider.

Kip Thorne, nobel laureate and long-time colleague of Stephen Hawking, is just one of several Kips who don't have a longer name. But Kip is often short for Christopher.

Ike, once the quirky one-person nickname of President Dwight Eisenhower, has morphed into a cool kid nickname of the early 21st century.

Rock definitely has a macho image, if a somewhat caricatured one, ala The Rock. But with the rise of word names and also of tough guy names, Rock feels more plausible than it did a generation ago.

Kent is a no-nonsense, brief, brisk one-syllable name, almost as curt as Kurt.

A top ranking choice in England and Wales, making frequent appearances on the Telegraph Announcments, Rafe feels equal parts rugged, amiable, and posh. Traditionally seen used a variant of Ralph (itself from the Old Norse Ráðúlfr), it came into use in the 17th century to reflect this particular pronunciation.

Perfect name for TV Frasier's effete brother. In the 2020 film Palm Springs, Andy Samberg plays a character with the updated spelling Nyles.

This up-and-coming single-syllable name has a few famous bearers, including baseballer Cale Iorg and Canadian hip-hop musician Cale Sampson. Sounding like Kale, this name also has a crunchy, hipster vibe.

A lot of attention was drawn to this name when Kim Kardashian and Kanye West announced it as the name of their baby daughter, making it instantly unisex.

Though some may find such names rather harsh and severe, increasing numbers of parents are gravitating toward this kind of flinty, steely, stony single-syllable name.

Leif is one of the most recognizable Scandinavian names, thanks to Icelandic explorer Leif Erikson, and is still one of the best, with a pleasant aural association with the word leaf.

Thor, the powerful name of the Norse god of thunder, strength and rain, would make a bold statement. Long a comic book staple, Thor has now invaded the big screen, and could land on birth certificates as well.
