Fairly popular a hundred years ago but out of the US charts since 1978, the quirky yet edgy Roscoe feels very much in step with the trending o-ending boy names popular now, such as Milo, Hugo, and Otto. A Top 1000 choice in the UK (albeit near the latter end), it could make a cool alternative to Ross, Russell, Robert, and Ronan.

Llewellyn/Llywelyn is a common patriotic first name in Wales, with its distinctive Welsh double LL's; in the U.S. Llewellyn would make a daring choice, though with the chance that some might find the ellen sound slightly feminine.

Ellis is a former Old Man Name turned gender-neutral choice for the 21st century. It's one of the less used names in the currently popular El-family, unless you're in the UK, where it's a Top 100 choice.

Atlas is one of those names that was previously thought too powerful for a baby boy, who would have to be strong enough to carry the world on his shoulders. Now Atlas has joined the pantheon of Greek and Roman god and goddess names in the realm of possibility, along with Mars, Zeus and Apollo.

Owen, a resonant Celtic name, has ranked among the Top 100 boys' names in the US for 20 years and is now at its highest point ever.

Otto is cool again. Long a quintessential Old Man Name, Otto has been promoted to trending darling of adventurous baby namers.

Gentle but grandiose and beloved by British novelists including Evelyn Waugh and P. G. Wodehouse, Ambrose was a fast rising name in 2022. Entering the UK Top 1000 for the first time and proving popular among Nameberry users, its elegance, softness, and vintage style means it fits in with popular Theodore, Sebastian, and Jeremiah.

Vincent is a name with a complex image. After being quietly used for centuries, it is suddenly seeming stylish, along wih other V names. Even the nickname Vince has been given a reprieve via actor Vince Vaughn and country singer Vince Gill. Vin Diesel was born with the more prosaic name Mark Vincent.

Reminiscent of the Old West, with rugged charm and a gentle, easy-going feel, Wesley has long been a staple on the US charts.

Calvin is a slightly quirky but cozy name that has a fashion edge thanks to Calvin Klein. It has been steadily on the popularity list since records were kept, never lower than Number 250, peaking in the 1920s, the era of the Calvin (originally John Calvin ) Coolidge presidency.

Otis has real appeal for parents attracted to its catchy O initial and combination of strength and spunk. The appealing hero of the British TV show Sex Education has done much to propel Otis into the forefront of cool names.

With a touch of celestial power, a hint of clunky charm, and the totally cool -o ending, Cosmo may well be finally shaking itself free of both the Seinfeld association (which made it a punchline of a joke) and the cartoon fairy association from The Fairly OddParents. In fact, it is in the Top 1000 in the UK and a favorite on Nameberry.

Robert was the Number 1 boys' name in the US in both 1925 and 1950, and in fact was in the Top 25 for more than a century, giving it true classic status. Strong if not quite stylish, Robert remains in the Top 100 for baby boys as a family favorite.

Solomon, a name that evokes wisdom and peace, is an Old Testament name that, along with other patriarchal classics, is finally beginning to shed its long white beard and step from the pages of the Old Testament into modern nurseries.

Archie made global news as the surprise first name of the newborn royal baby, son of the Duke and Duchess of Sussex aka Harry and Meghan. Archie has now officially transcended Archie Bunker and Riverdale's Archie to take the, um, throne as the quintessential retro nickname name.

Harvey, which was brought to England by the Normans, is a genial, old-timey name that has been much more popular across the pond in the UK. It was a Top 100 choice in England & Wales from 1997 until 2021, though 2022 saw it fall just slightly.

Claude is a soft-spoken French name that conjures up the pastel colors of Monet and harmonies of Debussy. In France, it is used for girls as well, in fact in the Tracy Chevalier novel Lady and the Unicorn, the protagonist is a female Claude.

Now that it's no longer fashionable for girls, Robin is rising for boys again. Robin Hood, Robin Williams, Christopher Robin, and Robin the Boy Wonder are all male namesakes, after all. It reentered the US Top 1000 boys names in 2015 for the first time since 1999 and continues to bounce around the lower end of the Top 1000.

Can Linus lose its metaphorical security blanket and move from the Peanuts page onto the birth certificate? We think it has enough charm and other positive elements going for it for the answer to be yes.

In the past, Orson has felt like a one-person moniker, tied to film director Orson Welles, who dropped his given name of George in favor of his more distinctive middle. While the Citizen Kane creator seemed to own the name during his lifetime, it's now an interesting possibility for any parent seeking an unusual yet solid name. It's started to appear to the celeb set too -- both Paz Vega and Lauren Ambrose have little Orsons.
