Jaunty, Spunky, Energetic Brits

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.

Jaunty, to say the least, Jonty might be an option if Johnny feels too old school. It has been noticed most often on the playing fields, as in U.K. rugby player Jonty Parkin (born Jonathan) and South African cricketer Jonty Rhodes (Jonathon).

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.

This aristocratic, somewhat formal Germanic route to the popular Leo is a royal name: Queen Victoria used it to honor a favorite uncle, King Leopold of Belgium. Though Leopold sounds as if it might be a leonine name, it's not really a relative of such choices as Leon, and Leonard.

Loyal is one of the few virtue names suitable for boys, an honorable and principled Boy Scout-esque appellation with a surprisingly long and distinguished history.

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.

Monty, a name with a World War II feel, is rarely used on its own. But we're hearing rumblings of a comeback and think that Monty, whatever it's short for, is an adorable vintage nickname name of the future.

Mungo is one of the most classic Scottish names but perhaps also among the most difficult names to carry. There is a St. Mungo whose proper name was Kentigern; he is the patron saint of Glasgow.

Orson has had in the past a rotund teddy-bear image, a la Orson Welles, who early on dropped his common given name of George in favor of his more distinctive middle one, and who seemed to own it during his lifetime. No longer a single-person signature, it's now an interesting possibility for any parent seeking an unusual yet solid name. It's started to appear to the celeb set--both Paz Vega and Lauren Ambrose have little Orsons.

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.

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.

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.

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).

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.

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.

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.

We love this partly for purely personal reasons, since it is one of our surnames. We used it as the middle name of a son –and it can make a good first choice too. Redmond – also found as Reamann or Raemonn – is the Irish form of the Germanic name that occurs in modern English as Raymond.

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.

Rollo is a livelier, roly-poly, o-ending version of Roland.

Rufus is a rumpled, redheaded (it was the nickname for red-haired King William) ancient Roman name popular with saints and singers (e.g. Rufus Wainwright); now, Rufus is on the cutting edge of cool.
