Jaunty, Spunky, Energetic Brits

Felix is one of those ancient but nontraditional names for boys that have come into favor over the past few decades, a favorite of parents who want a masculine name with history and heft that breaks ranks with the standard Franks and Freds. Felix is also an international darling, ranking in the Top 100 in several European and English-speaking countries.

Milo is most commonly considered to be Germanic name derived from the Latin word miles, meaning "soldier." However, there is evidence to suggest it also may have independently spawned from the Slavic root milu, meaning "merciful." Milo predates brother name Miles, a variation that evolved when the name immigrated to the British Isles in the Middle Ages. Mylo is an alternate spelling.

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.

Oscar is one of the most stylish Old Man Names of our era. While it's softened slightly in popularity over the past 20 years, that may be considered a very good thing.

Jaunty and raffish, Rafferty is one of the most engaging of the Irish surnames, used by Jude Law and Sadie Frost for their son. Fortunately, it doesn't still go by its original form: O'Raighbheartaigh.

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.

Jasper originated as a variation of the Latin Gaspar, which ultimately derived from the Persian word ganzabara, meaning "bringer of treasure." As a given name, Jasper’s etymology is unrelated to that of the gemstone, which comes from a Semitic word meaning "speckled stone." Jasper is the usual English form for one of the Three Wise Men who brought gifts to the infant Christ according to medieval tradition and appears in the Bible as a reference to the stone itself in Revelations 4:3.

Hugo, the Latin form of Hugh, has more heft and energy than the original -- and of course we love names that end (or begin, for that matter) with an o. This one is especially appealing because it's backed up by lots of solid history and European style.

Actor Kit Harington, aka the dreamy Jon Snow on Game of Thrones, has given this nickname-name new style and appeal for boys. Actress Jodie Foster used it for her son back in the 2000s, while actor Kit Connor of Heartstopper fame may have introduced it to a wider audience.

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.

Walter was seen as a noble name in the Sir Walter Raleigh and Sir Walter Scott era, but it then spent decades in baby name limbo. Now quite a few independent-minded parents are looking at it as a renewable, slightly quirky, classic, stronger and more distinctive than James or John, second only to William among the handsome classic boy baby names starting with W.

Gideon is a no-longer neglected Old Testament name, but still makes an excellent choice for parents looking to move beyond such overused biblicals as Benjamin and Jacob. In the Old Testament, Gideon was a judge called on by God to rescue the Jews from the Midianites, and the name was popular among the Puritans.

Ivo is an unusual, catchy name with the energetic impact of all names ending in 'o'. Hardly heard in the U.S., it is used a bit more frequently in England, as is the related Ivor, a favorite of such novelists as Evelyn Waugh and P.G. Wodehouse. Ivo is currently most popular in the Netherlands.

Percy is an adorable old name that is finally shedding its pampered Little Lord Fauntleroy image in this new era of boys with soft yet traditionally male names like Jasper and Elijah. Originating as an aristocratic Norman name, Percy became fairly widespread in England--and to some extent in the US--as an offshoot of the fame of the poet Percy Bysshe Shelley.

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.

Quirky in the way that all Q names are quirky, Quincy was once a buttoned-up, patrician New England name, an image countered in recent years by the talented and ultracool musician Quincy Jones (middle name: Delight; nickname: Q).

The sophisticated Edmund and its nearly-identical French twin Edmond are coming out of mothballs now that Edward, inspired by Twilight, is once again a hot name.

This name is a classic example of an underused golden oldie that ticks so many boxes - unusual yet traditional, heaps of cute nicknames, a statement name that exudes retro cool. Aloysius is the Latin form of many more common names like Louis, Luis, Luigi and the uncommon but symphonically familiar Ludwig.

Ralph has two diametrically different images: there's the suave Ralph Fiennes-type Brit (often pronounced Rafe), and then there's the Jackie Gleason blue-collar, bowling blowhard Ralph Kramden bus driver. It's all in the eye of the beholder, though its hip factor did rise when it was chosen for his son by cool U.K. actor Matthew Macfadyen.

Used almost exclusively in England; would make an equally amiable short form here for Raphael or Rafferty -- and could also stand on its own. If you're looking for boys' names starting with R, this is one of your cooler choices.
