Aeson 

One of several blunt B names just this side of the gender divide. While its short and to-the-point sound may feel modern, it has been declining steadily since the 1980s.
 David Brent is Ricky Gervais's character in the UK version of The Office.

Carter has ranked in the Top 100 since the the turn of the millennium, but despite its recent popularity, it's not a trendy new name. In fact, Carter is one of those names that just misses ranking in the US Top 1000 for its entire 140+ year history. 
 
Carter's off its recent popularity peak now, but it's getting some fresh style via Beyonce's country album Cowboy Carter, which references the surname of her husband Jay-Z aka Shawn Carter.
 
Having hot characters named Carter on both Gossip Girl and The OC probably didn't hurt Carter's rise, along with Noah Wyle's Dr. John Carter on ER, who was always called by his last name. Carter also, of course, has presidential cred.
 Carter is especially popular in the Midwest, having recently been Number 2 in Nebraska and Number 3 in Iowa, as well as spreading north to Canadian provinces Saskatchewan (recently Number 2) and Manitoba (recently Number 5). It does straddle the line between country and city, another reason for its longtime appeal.

Flynn, a charming Irish surname, is still used only quietly, despite its easygoing, casual cowboy charm, unlike Finn which is a star of this genre. Flynn was the choice of Orlando Bloom and Miranda Kerr for their baby boy, and is also the middle name -- used as his first -- of a son of Miranda's fellow supermodel Elle Macpherson, of Gary Oldman's son Gulliver and Marley Shelton's daughter West.
 Flynn Rider (born Eugene Fitzherbert) is the dashing animated hero of the Disney film "Tangled." On TV's "Breaking Bad", Flynn was what young Walter Jr. tried to rename himself. The name was long associated with the swashbuckling Errol Flynn, inspiration of the phrase "in like Flynn." Some may connect this name to controversial former National Security Adviser Michael Flynn
 Flynn entered the U.S. Top 1000 in 2011, and is a highly popular choice in Australia and New Zealand.

A modern spelling of an already modern sounding name, Kash is a spelling variant of the name Cash. Like Kairo, Karter, Karson, and Krew, that K initial gives it a very 21st century feel.
 
Kash can be considered an old occupational name, derived from the Latin capsa, meaning someone who makes boxes. It also, and perhaps more obviously, sounds just like the English word cash meaning money, giving it a slightly celebrity-name vibe, like Saint, Reign, and Sir.
 
In fact, the name Cash didn't enter the US Top 1000 until 2003, the year American musician Johnny Cash died. The Kash spelling followed it onto the charts in 2008, suggesting both names were originally celebrity-inspired.
 
Alternative origins for the name could be as a derivative of the Roman names, Cassius and Cassian, meaning "empty" or "hollow", or from the Hindi and Urdu name Kashmir or Kasmir, the name of an Indian subcontinent. 
 
Until 2021, Cash was always the preferred spelling in the US, however in more recent years, Kash has ranked slightly higher. Given to over 1300 babies in the US each year, it fits in with a number of other 'ash' names currently in style.

Kash

Kobi

A name that defines itself, a bit more curt in the harder K version.

According to exclusive Nameberry data, Logan is officially the Number 1 gender-neutral name in the US, but that statistic is somewhat misleading given that nearly 90 percent of the baby Logans born in 2023 were boys.
 
Logan started climbing in the mid-70s and shot up to the Top 5 for boys in 2017. Now, Logan's popularity has settled back down to the boys' Top 50 in the US and the Top 100 in other English-speaking countries.
 The mutant character Wolverine, known as Logan, based on the X-Men comics and played by Hugh Jackman on film, has had a considerable impact on the name. There were also attractive guys named Logan on Veronica Mars and Gilmore Girls, though Succession patriarch Logan Roy may have given the name a harder edge.
 
Logan originated as a Scottish surname which was derived from a place of that name in Ayrshire. The place name came from lagan, a Scottish Gaelic diminutive of lag, meaning "hollow." Alternate spellings include Logon, Logen, and Logyn, which is more common among girls.
 Logan is used for girls less often now than it was in the mid-nineties. A little over ten percent of the baby Logans today are female, down from about 15 percent in 1995.

Rio is a reductive ranchero place-name with an attractive Tex-Mex lilt. No Doubt's Tom Dumont has a son named Rio Atticus. 
 Also a South American place name, and associated with the Rio Grande, it's been used as a swaggering cowboy name in films spanning from a William S. Hart character in 1915 to Marlon Brando's in One-Eyed Jacks. It is occasionally used for a girl, as in the catchy Duran Duran song.

Slater has a more genial, friendly feel than most trade names. Angela Bassett and Courtney B. Vance used it for one of their twins. 
 On the nineties TV show Saved by the Bell, the character A.C. Slater, played by Mario Lopez, was usually referred to by his surname. Christian Slater is a well-known real life bearer--though he was born Christian Hawkins.

Slater

A few decades back, this name -- which hardly shows its Irish roots -- evoked a man in a gray flannel suit; now, though still upscale, it's more likely to be attached to a female. 

Sloan

This strong single-syllable <a href="https://nameberry.com/boys-names">boys’ name</a> has been finding favor with parents since the fifties, though it's been slipping in recent years; it fell out of the Top 500 for the first time since 1959 in 2015. Its main associations have been with the River Trent, whose name dates back to prehistoric times, and with former Mississippi Senator Trent (born Chester) Lott, and Trent Reznor (born Michael) of Nine Inch Nails. 
 In the eighteenth century, William Trent founded a settlement, which became the city known as Trenton (Trent's town), and that morphed into a first name for boys.
 (James) Trent Olson is the only brother of the three Olson sisters; Trent Ford has been seen on Gosford Park, The West Wing and Vampire Diaries. And the name of the Vince Vaughn character in the 1996 movie Swingers is Trent.

Trent

Originally a nickname for a third-generation son, as in Thurman Thackeray III, Trey is now being given to others, and it has also expanded to Treynor and Treyton. The name also is popular among basketball fans: It's another word for a three-point shot.

This familiar but never popular Welsh surname name might be a good Sean alternative-- and we're starting to hear some berrybuzz about it. Vaughn is an alternate spelling.

 There have been three major musical bearers of the name: British classical composer Ralph Vaughan Williams, 1940's U.S. band leader and singer Vaughn Monroe and the great jazz vocalist Sarah Vaughan. And two more current surnamed Vaughans: comic actor Vince and musician Stevie Ray.

Western novelist Zane (born Pearl!) Grey made this name famous. Now, it's in tune with the style of our times, retaining that appealing cowboy image. 
 Zane Grey was the great-grandson of Ebenezer Zane, founder of Zanesville, Ohio, the town where the writer was born. The name Zane has been on the popularity list since 1921, the heyday of such Zane Grey novels as The Riders of the Purple Sage.
 The Arabic name Zayn, as in musician Zayn Malik, sounds exactly the same as Zane but has a different root. Zayn is one of the fastest-rising names in recent years. And some parents--including country singer Mindy McReady -- use the spelling Zayne.
