Despite its origin as a patronymic meaning "son of Adam", Addison really caught on for baby girls in the US around the turn of the millennium, following in Madison's footsteps to peak at #11 in 2007 and again in 2010. But there are plenty of distinguished namesakes for a boy named Addison: from the fictional theater critic Addison DeWitt (All About Eve) to the 18th-century English poet, playwright, politician and essayist Joseph Addison. It is worth noting too, that Addison remains in usage for boys in the UK and would fit right in with other unisex choices, such as Mackenzie, Hadley, and Ellis.

Addison

The recent ascent of this English surname is due to two things: the megapopular Ash beginning and TV/movie hottie Ashton Kutcher. The name peaked at Number 76 in 2004, a year after Ashton Kutcher's (both Christopher Ashton) hit TV show Punk'd made its debut.

Ashton

Avery is a unisex name that is used four times as often today for girls as for boys. But while Avery's popularity is starting to soften for girls, it continues to get stronger for boys -- in keeping with our finding that gender neutral names are becoming more favored for boys than for girls.

With its friendly, sensitive, and approachable feel, Cameron is a 90’s favorite that remains popular today. It has a pleasing balance of soft and strong sounds, and holds unisex appeal, thanks to Cameron Diaz. 
Derived from a Scottish surname which in turn comes from the name of a West Highland Clan, Cameron means “crooked nose” in Gaelic. 
Not the best of meanings, perhaps, but it is likely to have originated from a nickname given to an 8th century member of the clan. Such nicknames were common in Highland culture, and it lends the name a rugged, outdoorsy feel. 
Used sporadically in the early half of the 20th century, Cameron became a popular choice in Scotland from the 50’s onwards. Shortly afterward, it began to accelerate up the US charts, really taking off in the 90’s, and peaking at #31 in the year 2000. 
Its popularity spread to Australia, England and Wales, Canada, and to France too, where it remained a top choice into the early 2010’s. Since then, it has been on a mostly downwards trajectory, though it is still given to 5000 boys – and 600 girls – in the US every year. 
Many will associate it with Cameron Frye, the anxious, slightly awkward, but good-hearted best friend in the movie Ferris Bueller’s Day Off. Actress Cameron Diaz is another memorable namesake, whose fame popularized Cameron as an option for girls too. 
A favorite in the sporting world, the name is worn by American footballer Cameron Jerell Newton, tennis player Cameron Norrie, and Olympic swimmer Cameron McEvoy, just to list a few. 
These sporty associations help to give Cameron an energetic vibe to complements its soft and calmer sounds, giving it a more “all-rounder” feel. 
Enjoy Cameron, but feeling put off by its meaning or popularity? You could try Camden, Caspian, Callum, Callahan, Cormack, or Cambell instead.

Cameron

For a generation, this name will always be linked to 1990s hit TV series Friends. Whether this is a positive or a negative will depend on your fondness for the show, and character Chandler Bing, but this name deserves consideration beyond these connotations: Chandler is a fresh take on the professional surname names.

Chandler

Courtland, with its added U, is an English form of the Dutch habitational surname Cortlandt. Cortlandt was a village near modern-day Wijk bij Duurstede, Netherlands. Its name was derived from the Dutch elements cort, meaning "short" or "narrow," and landt, "land."

Courtland

Dalton is a name with multi-faceted appeal. Many are attracted to the name's resemblance to other two-syllable n-ending favorites: Colton, Holden, and cousins. Others see it as a trendy Western name, recalling the legendary Dalton Brothers gang. It also has something of an upscale, preppy feel connected to the exclusive New York private school. 
 The most well known bearer of the name is blacklisted screenwriter Dalton Trumbo, but there have been a number of high-profile fictional Daltons as well. Dalton Rumba was an adult character on Glee, Clive Owen played a Dalton in Inside Man, there was a scholarly Dalton on Buffy the Vampire Slayer, and Patrick Swayze opened the film Roadhouse by stating "My name is Dalton Russell."

Dalton

Ellery is a rhythmic three-syllable boy's name that is familiar and yet rarely used--and just waiting to be discovered. It's long been identified with Ellery Queen--which was both the pen name of two cousins, Frederic Dannay and Manfred B. Lee, and the detective they created.
 Laura Dern and Ben Harper chose it for their son.

Ellery

Less popular than Emery, this name also attributes to Emory University. Both spellings of the name lean more heavily to the girls' side, but this one is not quite as unbalanced.

Emory is used about 40 percent of the time for baby boys, while with Emery, it's only a bit over 10 percent.

Emory

Fallon was one of the first of the unisex surname names, but thanks to "Dynasty" in the 1980s it now has a feminine image.  For a boy, try Phelan instead. 

Fallon

Ferrell

Forrest is one of the earliest appealingly sylvan, outdoorsy choices, borne by newsman Sawyer, actor Whitaker, and football Hall of Famer Gregg. Forrest Gates was a character on "Buffy the Vampire Slayer."
 Forrest was steadily on the US popularity list until 2003, reaching a high of Number 175 in 1913, and then received a somewhat surprising blip after the release of "Forrest Gump." It started rebounding again in 2013, when it reentered the Top 1000 as one of the fastest-rising names on the list.
 Early Forrests were named in honor of Confederate General Nathan Bedford Forrest, head of a famous cavalry force, who advised 'Git there fuster with the mostest men.'

Forrest

Surely one of the most pleasant and evocative of the occupational options.

Gardner

Gatlin has risen into the Top 1000 in recent years on the strength of its association with the Olympic champion sprinter Justin Galtin as well as the Gatlin Brothers of Nashville fame. The name has the same root as gadabout, thus the meaning related to wandering.

Gatlin

Gavin, a name with Scottish roots, has stepped into the spotlight, replacing the dated Kevin, thanks in part to pop-rock sensation Gavin DeGraw and Bush lead singer Gavin Rossdale. 
 Gavin also has made literary appearances in J.M. Barrie's The Little Minister and in William Faulkner's Snopes family trilogy. In the form Gawain, he was one of the Knights of King Arthur's Round Table.
 Gavin entered the ranks in the 1950's and climbed as high as Number 30, in 2008, before dropping a bit on the charts.

Gavin

Grayson, which you might think of as a Jason-Mason substitute, has been rising through the US Top 1000 since 1984 and has ranked in the Top 100 since 2011. 

That makes Grayson a modern classic boys' name, with both a sober buttoned-up feel as well as an unconventional masculine vibe. Grayson might plausibly be a banker or an artist, and its resemblance to its female counterpart Grace gives it a feminist gloss.
 
Grayson's biggest problem, if you consider it one, is its persistent, widespread popularity. The Greyson spelling also ranks highly in the US and throughout the English-speaking world, and a wide range of alternative spellings including Gracen, Gracyn, and Greysun have sprung up for baby girls and boys.
 
Last year, about 11,000 baby boys in the US were named Grayson and Greyson alone, as many s were named William or Henry, making it a solidly Top 10 name.

Grayson

Holden is a classic case of a name that jumped out of a book and onto birth certificates--though it took quite a while. Parents who loved J. D. Salinger's The Catcher in the Rye are flocking to the name of its hero, Holden Caulfield -- not coincidentally in tune with the Hudson-Hayden-Colton field of names. (Trivia note: Salinger supposedly came up with the name while looking at a movie poster promoting a film starring William Holden and Joan Caulfield, though other sources say he was named after Salinger's friend Holden Bowler.) Another impetus was provided by a soap opera character introduced in 1985.
 Among the celebs who have chosen Holden are Brendan Fraser and Mira Sorvino.
 In Australia, only a car-lover would choose this name, which is inextricably linked with the car-brand.

Holden

While Kendall originally started as a <a href="https://nameberry.com/boys-names">boys’ name</a>, and remained more or equally popular for boys until the early 1990s in the US, it now feels almost synonymous with Kendall Jenner, of Kardashian fame. The proportion of female to male Kendalls is currently running at about five to one. One male Kendall in the spotlight is the character Kendall Roy on TV's Succession.
 The name Kendall started life as a locational surname, referring to the town of Kendale in England.

Lachlan is as Scottish as haggis and tartan plaid kilts—a favorite used throughout England, Scotland, Australia, and New Zealand—and just beginning to be noticed in the US: it reached the Top 1000 for the first time in 2013. An ancient name, Lachlan was originally used to describe the Viking invaders of Scotland, those from the land of the lochs.
 Americans and Australians tend to pronounce the first syllable of the name like Lock, but the genuine Scottish pronunciation sounds more like Lack.
 In Ireland, the name was Anglicized as Laughlin; in Scotland the pet forms are Lach, Lachie, or Lockie.
 Lachlan has been a top name in Australia for at least a decade. It has been in the headlines recently via the eldest son of media mogul Rupert Murdoch.
 Somewhat surprisingly, Lachlan has US presidential cred, as the son of tenth president John Tyler, whose other children included Lyon, Letitia, Tazewell, and Pearl.

Lachlan

The additional syllable makes Lark a masculine surname name. 

Larkin

More popular in its Layton spelling, Leighton is rising in popularity in the US for both sexes simultaneously, although this spelling remains more popular for girls for now – no doubt helped by actress Leighton Meester. Lleyton – as in Australian tennis star Lleyton Hewitt – is another, even more complicated, variant spelling.

Leighton

Lennox is an aristocratic and powerful Scottish surname name made truly special by that final x. The worldwide fame of British boxer--World and Olympic champion--Lennox Claudius Lewis brought the name into the spotlight as a first name, while as a last it's tied to Eurythmics singer Annie L.
 The Thane of Lennox appears in Macbeth, Mary Lennox is in The Secret Garden and there are two Agatha Christie characters with the name.
 Lenox is another accepted spelling.

Lennox

The graceful, natural image of the verdant shade tree transcends any connection with President Johnson.
 A sturdy tree that can live for centuries, Linden was actually quite a popular boys' name from the 1930s to the 1960s--as was the presidential spelling Lyndon--but has now become unisex.

Linden

Logan started climbing in the mid-70s and shot up to the Top 5 in 2017. Now, Logan's popularity has settled back down to the 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 also used for girls, but less so 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.

Logan

This lively Scottish name caught on for girls in a big way starting from the 1970s in the US, although it has remained much more gender-neutral in its native Britain, where it peaked at #109 for boys in 2005 (#303 for girls the name year). Mac would be a cool short form.

Mackenzie

Madison was at one time a strictly boys' presidential name, reaching as high as Number 311 at the end of the nineteenth century.  That all changed in 1985 when it entered the girls' list, zooming up quickly until it reached the Number 2 spot, with more than 22,000 female babies given the name in 2001.  As is so often the case, its use for boys has dropped precipitously.

Madison

Mason is an occupational surname that ranked among the Top 10 name for boys throughout the 2010s, after its choice as one of the first Kardashian baby names.
Part of its appeal is as a fresher-sounding replacement for dad name Jason. It's also one of the leaders of the Jackson-Hudson-Grayson-Kayson trend.
Along with Kourtney Kardashian and Scott Dissick, Mason was chosen for their sons by several other celebrities, including Cuba Gooding, Jr., Melissa Joan Hart and Kevin Richardson (as well as by Kelsey Grammer for his daughter).
And there were two cute TV werewolves named Mason: Mason Greyback on Wizards of Waverly Place and Mason Lockwood on Vampire Diaries--a far cry from the name's wholesome image.

Mason

A happy medium between the weighty Maximilian and the laid-back Max, Maxwell is one of the most classic and attractive <a href="https://nameberry.com/list/428/scottish-baby-names">Scottish names</a>. Early influences on the name's revival include Maxwell Smart of the television show, and then movie, Get Smart, and the Beatles song about Maxwell's Silver Hammer.
 Lance Armstrong chose it for his son, but there was a sharp and unexpected gender switch when both Jessica Simpson and Lindsay Sloane both chose it for their daughters. Still, in the US baby boy Maxwells outnumber baby girls 50 to 1.

Maxwell

Morgan, once split evenly between the sexes, is a strong and attractive Welsh favorite, still a common <a href="https://nameberry.com/boys-names">boys’ name</a> in Wales. Morgan is now more often a girls' name in the U.S. – about 2000 girls were given the name in one recent year, vs. 362 boys – though it's one of the most traditional unisex choices. Morgan was actually a Top 200 pick for boys in Victorian Britain!
 Distinguished actor Morgan Freeman is a worthy male namesake.

Morgan

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

Paxton stands out from a lot of other two-syllable surname names for two reasons: the dynamic letter X in the middle, and its admirable peace association, providing the great nickname Pax.
 One well known bearer is the British actor Paxton Whitehead.

Paxton

Peyton is the most-used spelling of this popular name, thanks to football star Peyton Manning, but it's playing increasingly for the girls' team. The Manning family excels in all-star names, with brothers Eli and Cooper and dad Archie.

Peyton

Prescott is one of several distinguished, upper-crusty surnames beginning with P.
 There are several historical surnamed Prescotts, including William, a Massachusetts Minuteman and commander at the battle of Bunker Hill, and Samuel, a Revolutonary patriot who traveled with Paul Revere on the night of his famous ride. Prescott is also the first name of the father and brother of George H.W. Bush.

Prescott

An Irish last-name-first-name that could make a child feel distinctive, while still having the regular guy nickname of Quinn. Christine Taylor and Ben Stiller spelled their son's name Quinlin. 

 Quinlan would make a fitting choice for a fifth baby, since quin in Latin signifies five.

Quinlan

Rafael is perhaps the ultimate romantic Latino name, not a bad gift to give your son. The Raphael spelling is the original Hebrew version.

Equally appealing short forms include Rafe and Rafi.

Rafael

Ronan is the compelling legendary name of twelve Irish and Scottish saints that is now drawing some deserved attention; this cousin of the ascending Roman and Rowan was chosen by actor Daniel Day-Lewis and his writer-director wife Rebecca Miller in 1998, and more recently by actress Catherine Bell.
 Ronan is a Harry Potter name—that of a centaur who lives in the Forbidden Forest. Ronan Keating is an Irish singer, Ronan Farrow is a TV personality and Hollywood scion, and its presence as a surname is represented by young actress Saoirse Ronan.

Ronan

Sounds as if it should have a Sir before it or a shire following it. 

Stafford

A name with some sterling qualities, most associated with the British currency and silver markets. Sterling has several recent TV associations, with characters Roger Sterling (on Mad Men) and Sterling Archer (on Archer), and actor Sterling K. Brown (on This is Us).

Sterling

There's only one Trenton, New Jersey, but it's a widely used name, more for its fashionable -on ending than the reference to the city. Since 2007, however, Trenton has been on a steady decline. Trenten is another popular spelling. Two NFL players, Trent Richardson and the late TJ Jackson, have Trenton as first name.

Trenton

Warrick has recently come into the spotlight as the character Warrick Brown on the TV show CSI. The more conventional spelling is Warwick, a medieval English noble name.
