Acker is a surname name that has not seen much use to date, but given it's lush nature meaning (and the fact that it also means "friend" in Somerset slang) this could be a cute choice for parents looking for something fresh. An added bonus its link to English "Master of the Clarinet" Acker Bilk. The Dutch version, Akker, is also an option.

Acker

An x makes any name cooler, so that Baxter has a bit more pizzazz than the original Baker. Baxter had some currency as a first name a century ago--it was on the popularity lists sporadically from 1880 till the 1920s, peaking at Number 515 in 1886-- which means it's just about due for a comeback. And we can see Bax as a worthy follow-up to Max and Jax.
 Singer Ian Dury named his now-grown son Baxter, and Dr. Baxter Stockman was a scientist in the "Teenage Mutant Ninja Turtle" series. 
 Fun feminist fact: as an occupational name, Baxter was actually the word for a female baker. It's only used for boys now, but could legitimatelt be a unisex name.

Baxter

Might make a good middle name for the child of a musician, though people could think you were honoring your BMW. 

Beamer

Booker would make for a very cool name, for writers, reformers, R & B fans and those wanting to pay tribute to Booker T. Washington.

Booker T. Washington, born into enslavement, became a dominant figure in African-American history. Musician Booker T. Jones, of Booker T. and the M.G's, was named for Booker T.Washington. "Booker" was also the name of a short-lived TV crime drama series, spun off from "21 Jump Street".

Another reference plus for literary-minded parents, beyond the obvious book: the U.K. Man Booker Prize, awarded annually to the best novel.

 No longer on the US popularity list, it was as high as Number 177 in 1910 and would make for an old-school cool option today.

Booker

With its slightly cocky feel, this well-used surname is not often heard as a first. 

Brewster

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.

Carter

A variation on the popular Colton, Colter has been climbing up the US charts since 2010. Given to around 1000 boys each year, it is now in the Top 500, and ticks the boxes for being a cool occupational name with rugged, Wild West vibes, and for giving the familiar nickname Col, or the alternative, Colt. 
 
Parents choosing Colter might like it as an honor name for a Colin or an alternative to popular Carter, but its a name with some interesting history too. 19th century explorer John Colter was considered the first mountain man, spending months living in the wilderness, exploring what is now known as Yellowstone National Park and taking part in the Lewis and Clark Expedition. Several places in the US are named after him, including Colter Peak and Colter's Hell. 
 
Fans of Philip Pullman's The Northern Lights might also think of the character, Mrs. Coulter.

Colter

In the currently popular solid, serious, two-syllable mold. 

Culver

Has a fresh occupational name feel, combined with old-fashioned Currier & Ives charm. 

Currier

Dagger is one of the new <a href="https://nameberry.com/list/404/badass-baby-names">badass baby names</a>, a sharp and scary choice that some parents may feel arm their child for battle in a cruel modern world.

Dagger

Other occupational names would be more commonly accepted, though the Mad Men character has certainly brought it to the fore.

Draper

An uncommon surname name with that energetic -er ending. Might appeal especially to baseball fans.

Fielder

If you're seeking a solid but underused occupational name with a warm, friendly sound, and an earthy feel, Granger is one to consider. Associated with faming, grain, and the outdoors, it fits in with the likes of Colton, Sawyer, and Cooper, with a hint of classic George about it too. 
 Granger is much better known as a surname — think mid-century actors Stewart and Farley -- though currently, the fictional Hermione Granger of the Harry Potter series may well be people's main association. For some that could be a plus while for others, it would be a strike against it, but nevertheless, sound and style wise, Granger makes an uncommon but accessible first.
 
The name appeared briefly in the US Top 1000 back in 2021, but has declined slightly since then, with a recent count showing it was used on 180 boys in a year.

Granger

Harper got its start as a celebrity baby name when Paul Simon chose it for his now-grown son. Since then, other famous parents have followed suit: musician Tim Finn and actor Cecilia Peck both have sons called Harper.

Other high-profile Harpers, like author (Nelle) Harper Lee and starbabies Harper Burtka-Harris and Harper Beckham, are female, but it makes a handsome choice for either sex (and is in the US Top 1000 for both boys and girls).

Harper

Lively, friendly surname that might appeal to basketball fans. 

Hooper

Hunter has been dropping a bit for the past few years but is still one of the leaders of a distinctive band of boys' names that combines macho imagery (Hunter, Austin, Harley) with a softened masculinity. Hunter was for years attached to gonzo journalist Hunter S. Thompson; Josh Holloway used it for his son.

Hunter

One of the first generation of surname names, along with Porter and Morgan, Parker's still one of the most appealing and remains firmly in the Top 100 for boys. About three times as many boys as girls get this occupational name. The association with Charlie Parker gives Parker itself a jazzy edge, and it also has a nature-related meaning. Rosie O'Donnell has a son named Parker.

Parker

Piper's rising popularity for girls makes it an unlikely masculine choice.

Piper

Rainer is one of those <a href="https://nameberry.com">baby names</a> that is still under-the-radar but has been quietly gaining traction: The number of boys who've received the name has doubled in the past decade, to just under 50. Part nature name and part traditional <a href="https://nameberry.com/baby-names/494/german-names-for-boys">German name for boys</a>, Rainer can claim a place among the two-syllable r-ending baby names so fashionable for boys today.

Rainer

Ryder, one of the current favorite er-ending <a href="https://nameberry.com/boys-names">boys’ names</a>, has been in the spotlight since Kate Hudson and her rocker husband Chris Robinson chose it for their son in 2004. Very popular in several provinces of Canada, Ryder was chosen by John Leguzamo for his son and adorns Boy Meets World star Ryder Strong.
 In the past, Ryder was much more prevalent as a surname, as in American Old Master painter Albert Pinkham Ryder and Brideshead Revisited protagonist Charles Ryder. Not all came by it legitimately, however--Winona Ryder was born Winona Horowitz.
Trivia note: The Ryder Cup is a biennial golf tournament with competing teams from Europe and the US.

Ryder

Sawyer is a surname with a more relaxed and friendly feel than many others, and is one of the hottest occupational names right now, with the Nameberry seal of approval. Sawyer is becoming one of the <a href="https://nameberry.com/unisex-names">top unisex names</a>. Both Sara Gilbert and Diane Farr used Sawyer for their daughters, while it was given a boost as a boys' name by the character Sawyer on Lost, an alias for the character really named James Ford. 
 Kate Capshaw and Steven Spielberg were among the first to discover Sawyer when they used it for their son in 1992, the year it leaped up 356 places. 
 Sawyer is a relatively common surname--think Tom and Diane. It originated as an occupational name for a woodcutter, otherwise known as someone who worked with a saw.

Sawyer

Out playing shuffleboard at his condo and not expected back for several generations -- unless it morphs into a girls' name, a la Sydney. 

Seymour

This shimmery Age of Aquarius unisex flower child name is making a comeback, along with metal and gem names like Steel, Jade, and Ruby. 

Silver

Sutter is a new entry to the fashionable class of occupational surnames, brought to the fore by the hero of the 2013 indie film The Spectacular Now.  More masculine than Sutton and more distinctive than Sawyer, Sutter might be a good choice for the child of a shoe designer or shoe lover.

Sutter

Tucker has more spunk than most last-name-first-names, and also a positive, comforting ("Tuck me in, Mommy") feel. 
 Tucker got something of a preppy image via bow-tied conservative TV commentator Tucker Carlson, and quite the opposite from writer/blogger Tucker Max, author of the #1 best-seller I Hope They Serve Beer in Hell. Tucker Crowe is a character in the Nick Hornby novel Juliet, Naked.

Tucker

Windsor may have male references, such as Britain's royal House of Windsor and a tie's windsor knot, but this name also has a definite feminine feel, as in Windsor Rose. That seems appropriate, as Windsor is used equally these days for boys and girls. Nicknames might include Win, Wind, Windy, and Winnie.
