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.

Ian is Scottish form of John, derived from the Hebrew name Yohanan. It is an Anglicization of the Scottish Gaelic Iain, which is also a viable spelling. Ian was introduced to Americans by Ian Fleming, creator of James Bond.

No longer tied to the hapless Ace Ventura, this jaunty, high-flying nickname name is starting to take flight among celebrity and other parents, with its countless positive references to doing well in tests and poker games, on the tennis court and golf course, and in the air.

We've seen Ray regain his cool, but could this country/cowboy name epitomized by Roy Rogers (born Leonard Slye), Acuff, and Clark, do the same?

A name that has a bit of a shouldn't-I-be-a-middle-name sound, though still in use as a first for both genders. Lee might be a good choice if you want something that sounds at once traditional yet modern, unisex but not newly-minted.

Ben, the diminutive of Benjamin or Benedict, can easily stand on its own as a simple, strong, nice-guy choice, though it's somewhat attenuated. Ben is this generation's Bob or Bill.

Though this feels like a modern invention, Jay has been in use for centuries. Early Jays often were named in honor of founding father John Jay, whose surname derived from the jaybird. A popular mid-century choice, Jay was in the Top 100 from 1956 to 1970. In the last couple of decades he was replaced by such more elaborate forms as Jayden, Jaylen, and Jayce. But Jay could make a comeback in tandem with cousins May, Kay, Fay, and Ray.

Sam has long been used on its own for boys, as accepted standing by itself as it is as a short form of Samuel. Straightforward and down-to-earth, Sam is the name of the son of the co-stars of The Americans, Keri Russell and Matthew Rhys. Sam is one of the most popular names that start with S in the Western world, ranking higher in several European countries than it does in the US, where it's trended downward since the 19th century, though it's always been in the Top 1000.

Could Hal be the Jack, Max, or Gus of the future? It just might happen in the new nickname environment, especially with Cal and Cy feeling cool, and with the interest in vintage, cowboy-esque choices, considering Hal ranked in the US Top 1000 in the first half of the 20th century.

Whether it's used as a short form or on its own, this jazzy midcentury name is poised for a comeback along with brothers Ray and Walt.

Pax, one of the variations of names meaning peace that are newly popular in these less-than-peaceful times, got a lot of publicity when chosen by Brad & Angelina for their Vietnamese-born son. Parents attracted to Pax may also want to consider Paz, the unisex Spanish version, or Paxton, a growing-in-popularity surname choice that shares that magical X-factor.

Fox is one animal name backed by a longish tradition, and then popularized via the lead character Fox Mulder on X Files. Fox is simple, sleek, and a little bit wild, and could make an interesting middle name.

Rye has the potential to become the masculine version of Rue—a short and sweet name for nature lovers (and whiskey fans too!). Rye might be short for Ryder or Riley or Rylan or any Ry-beginning name, but increasingly it stands on its own. It can also be considered a place name, after the town in England.

Country artist Hailey Whitters and her husband, Jake Gear, chose this name for their son in 2025.

Ash has Southern charm plus the arboreal-nature appeal. Plus your little boy will prize Ash as the name of the hero of the Pokemon cartoons. Ash can also be a dashing short form of Asher, Ashton, or any other "Ash" name.

Joe is still the ultimate good-guy name, not at all diminished by its longevity or popularity or its everyman rep as Regular Joe, Cowboy Joe, G.I. Joe, Joe Exotic, Joe Blow, Joe Millionaire, Average Joe — and now President Joe (Biden).

The original Pip was the main character in Great Expectations (full name Philip Pirrip). Cute for a tike, maybe too cute for an adult.

In Ireland and Scotland, Mac and Mc mean "son of"; here, Mac is a generic fella, or a short form cooler than either Matt or Max. Mac can be a nickname of any longer Mac or Mc starting name such as McCoy or Macalister. If you want to make it feel more complete, you can always spell it Mack.

A friendly nickname for Joachim, also used independently in Finland, Sweden, and the Netherlands, Joa would be pronounced as YO-ah in Finnish, but more like YOO-a in Swedish.

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