Alec, though an old nickname for Alexander, is much fresher sounding than Alex, with the additional advantage, at least to some parents, of being distinctly male (there are as many girl Alexes these days as there are boys). While Alec has a clipped British image, it's actually one of the classic <a href="https://nameberry.com/baby-names/508/greek-names-for-boys">Greek names for boys</a>, by way of father name Alexander.
 Alec Baldwin is by far the best known current bearer of the name. In the past there have been actor Alec Guinness and writer Alec Waugh.

Beau suggests someone devilishly handsome, with a large measure of southern charm—a nice image to bestow on your boy. Often solely a nickname in the past, it's now standing firmly on its own. Beau has been on the Social Security list non-stop since 1969.
 Beau also has something of a dapper image, thanks to the fashionable Beau Brummell (born George), which led to the stylish New York mayor Jimmy Walker being called Beau James. Other notable Beaus had more formal names at birth—Beaus Bridges and Biden were both the third sons in their families to carry their fathers' names: Lloyd Vernet Bridges III and Joseph Robinette Biden III.
 P.C. Wren's novel Beau Geste was a major bestseller in its day and was also a popular movie—in that case Michael was the character's birth name. Many will remember that the child of Ashley and Melanie Wilkes in Gone With the Wind was called Beau, and there was also a Beau on the old TV western Maverick.
 And if you want a more substantial name on the birth certificate, try Beauregard.
 Art Garfunkel, Emma Bunton, Wendy Wilson, Jamie-Lynn Sigler, and now Tori Spelling all have sons named Beau.

Beau

Bruce is a Norman place name made famous by the Scottish king Robert the Bruce, who won Scotland's independence from England in the fourteenth century. It's perennially popular in Scotland, but has been rarely used here for a generation -- though the impact of Bruces Lee, Springsteen, Dern and Willis, as well as Batman's Bruce Wayne -- still lingers. At one time Bruce was so widespread in Australia, it became a nickname for any Ozzie man. An interesting alternative is Brix, the Normandy place name where the Bruce family originated.

Bruce

Calvin is a slightly quirky but cozy name that has a fashion edge thanks to Calvin Klein. It has been steadily on the popularity list since records were kept, never lower than Number 250, peaking in the 1920s, the era of the Calvin (originally John Calvin ) Coolidge presidency. 
 The name came into use as a first name in honor of John Calvin--born Jehan Cauvin-- the seventeenth century French Protestant reformer whose strict doctrines became the basis of Calvinism, and the name was taken up as a tribute to him.
 Other associations include the above-mentioned Calvin Klein (and his famous 'Calvins' ads), humorous writer Calvin Trillin, the comic strip "Calvin & Hobbes" --and it's also the birth name of Snoop Dog. Calvin O'Keefe is one of the main characters in Madeleine L'Engle's A Wrinkle in Time.

Calvin

A less-used cross between Clifford and Clinton. 

Clifton

The sophisticated Edmund and its nearly-identical French twin Edmond are coming out of mothballs now that Edward, inspired by Twilight, is once again a hot name.
 Edmund has had an enviable history, as evidenced by these quotes: "There is nobleness in the name of Edmund," says a Jane Austen character, and the poet John Keats once bemoaned, "Had my name been Edmund, I would have been more fortunate."
 Famous bearers include the English astronomer Edmund Halley, after whom the comet was named, poet Edmund Spenser, great Shakespearean actor Edmund Kean, and New Zealand mountaineer Sir Edmund Hillary. Literary Edmunds appear in King Lear,, Jane Austen's Mansfield Park, and Dickens's Little Dorrit.
 Edmund reached its highest point of popularity in the U.S. in 1914, when it was Number 130; it hasn't appeared on the list since 1997--making it even more attractive as an uncommon alternative to Edward.
 Eamon is the cheery Irish version.

Edmund

Popular in the 1920s, Eldon is a retro name that's waiting to be rediscovered. It has a similar placename/surname appeal to current Top 1000 names Alden and Holden. Several towns in the US and UK bear the name.

Eldon

Concise and clipped European version of the earnest Ernest. 

Ernst

Ezra has a lot going for it: the strength of its heroic Biblical legacy, its quirky sound, and its fresh but familiar feel. Ezra is now at its highest point ever, but its intuitive streamlined spelling and deep roots could make it a worth successor to Elijah in the Top 10 -- or even to Liam or Noah at Number 1.
 Ezra just misses being among the elite group of male names that's always been in the US Top 1000, having dipped below the cutoff in 1964 and '67. Ezra also makes the Top 100 for boys in other English-speaking countries along with the Netherlands.
 Ezra is an abbreviation for the Hebrew phrase Azaryahu, meaning "Yah helps". In the bible, Ezra led a group of fifteen hundred Israelites out of slavery in Babylon and back to Jerusalem. 
 
Other notable Ezras include poet Ezra Pound and New York Times political columnist Ezra Klein. Ezra Cornell was a founder of Western Union and co-founder of the university that bears his name and Ezra Jack Keats is a popular children's book author-illustrator. 
 Both Paul Reiser and Taylor Hanson are dads to boys named Ezra, and there are Ezras to be found in Wilkie Collins's The Moonstone and Daniel Deronda by George Eliot.
 And let's not forget the band—Better Than Ezra—along with rising actor Ezra Miller, Vampire Weekend musician Ezra Koenig or the character Ezra Fitz from Pretty Little Liars.
 As unlikely as it may seem, Ezra is also growing in popularity as a girls' name, making the girls' Top 1000 in 2018 ad still rising. About 450 baby girls were named Ezra last year, but about 8000 baby boys, which puts Ezra below our 10% minimum to be considered a unisex name.

Ezra

As this long-term Age of Jordans, both male and female, begins to wind down, the neglected Scottish favorite Gordon, with its more distinguished history, could come back as a distinctive alternative. Gordon is one of the most classic authentically <a href="https://nameberry.com/list/473/scottish-names-for-boys">Scottish names for boys</a>. 
Originally a surname, it was used in honor of nineteenth century general Charles George Gordon, killed defending the city of Khartoum. Conservative but not stodgy, Gordon was a Top 100 name from 1911 to 1943 and is showing some new signs of life. It fell off the charts in 2009 and reentered in 2014.
 A contemporary political headliner is former Prime Minister Gordon Brown (born James Gordon), and other distinguished bearers of the name have been photographer and film director Parks, Scottish celebrity chef Ramsay, and the beloved "Sesame Street" character Gordon Robinson. We won't even mention that symbol of corporate greed from the 80's movie Wall Street.

Gordon

The name of the last Anglo-Saxon king of England before the Norman conquest, and a name that's long been associated with a pipe-smoking, bespectacled grandpa or uncle.
 
After years in style limbo, Harold is slowly making a comeback, possibly boosted by cheerful nicknames like Harry and Hal. Filmmaking couple Greta Gerwig and Noah Baumbach have a son named Harold.

Harold

Harvey, which was brought to England by the Normans and is a version of the French name Herve, is a genial, old-timey name that has been much more popular across the pond. It has been a Top 100 choice in England & Wales since 1997.

 In the US, Harvey is an under-the-radar classic which currently sits just below the Top 400. It has been climbing steadily since the early 2000s, with only a slight dip following two of the biggest bad-news stories of 2017, the Hurricane Harvey and convicted sexual offender Harvey Weinstein. Since then, the name has bounced back – a tribute to Harvey's classic charm.

 Harvey previously had a respectable run as a Top 100 name in the US in the late nineteenth and early decades of the twentieth century.

Harvey

Hiram is the kind of forgotten biblical name that adventurous parents who wish to move beyond David and Daniel are beginning to reconsider--even though it has bits of its old stiff-collared image clinging to it, along with a little hillbilly feel as well. 
The name belonged to an Old Testament king of Tyre who helped David and Solomon plan and build the temple in Jerusalem, and was a favorite in the eighteenth and nineteenth centuries, though a couple of well-known bearers dropped it--Ulysses S. Grant was orignially Hiram Ulysses Grant, but he didn't like having the initials H.U.G., and country singer Hank Williams was also born Hiram.
With its definite funk factor, and its friendly nickname Hi, Hiram would make a distinctive choice.

Hiram

Howard, once hugely popular -- in the Top 50 from the 1870s to early 1950s, hitting Number 24 in 1920 -- has been stuck in Dad-Grandad limbo for decades, but is showing some signs of stirring back to life. Along with such formerly-fusty names as George and Harold, Howard may soon feel baby-appropriate, perhaps with the short form Ward.
Howard was the surname of an early English noble family, gradually metamorphosing into a first name in the nineteenth century. Notable Howards include tycoon Howard Hughes, director Howard Hawks, politician Howard Dean, and media figure Howard Stern. In literature, there is Ayn Rand's iconic architect Howard Roark, protagonist of The Fountainhead.
 Strange trivia item: Vampire novelist Anne Rice's given name is Howard Allen. She has said her mother "had the idea that naming a woman Howard was going to give that woman an unusual advantage in the world."

Howard

Patrician to the core, Hugh was firmly in the Top 100 until 1903. It's never achieved those heights again, though it has always managed to remain in the Top 1000, scraping bottom at literally Number 1000 in 2006 before reversing course and heading back upwards.
 Hugh has always been particularly prevalent among the Irish—there have been 20 Irish Saint Hughs, and it's traditionally associated with the O'Donnell clan. Hugh was an early immigrant to the New World, where there were two Hughs in the first English-speaking settlement in America. Hugh's biggest drawback is its sound, barely more than an exhaled breath. 
 
Actor Hugh Jackman adds a dash of the romantic hero, and other prominent Hughs include Hugh Laurie (born James Hugh), Hugh Grant, and Hugh Dancy. Then there's Hugh Hefner, known to the world as Hef. 
 Hew and Huw are the distinctively—probably too distinctively—spelled Welsh forms.
 A modern alternate option would be the surname Hughes.

Hugh

Ike, once the quirky one-person nickname of President Dwight Eisenhower, has morphed into a cool kid nickname of the early 21st century. 

The rise of Isaac and the stylishness of short down-to-earth nicknames like Max and Gus means that many parents like Ike once again. In the Top 200 (!) at the end of the 19th century, Ike fell off the Social Security Top 1000 by the end of Eisenhower's presidency in the late 1950s.

We do foresee the comeback of Ike, bur probably as a short form of Isaac or Isaiah.

Mack, when "formalized" with the final k, makes an engagingly amiable choice, a far more uncommon alternative to the ubiquitous Max and Jack, with a nice, every-guy feel. Mack entered the popularity list in 2009 for the first time since 1989 and continues to climb. However, it's still far from its peak — it was a Top 100 name in 1900.
 Mack (born Michael) Sennett was the innovator of slapstick comedy in silent films. The name is also suggestive of Mack the Knife and a whole family of computers. Kevin Kline, Cuba Gooding, Jr., Dan Aykroyd, Eric Roberts and Snoop Dogg have all played characters named Mack.

Mack

This bold choice soared in popularity from 2008 to 2013, and now seems to have plateaued. But watch out—the character Major Major Major Major in the classic absurdist novel Catch-22 had a terrible time.

Major

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.
 
Milo has long been a favorite <a href="https://nameberry.com/boys-names">boys' name</a> on Nameberry, also getting some well-deserved appreciation in the wider world. Milo combines the strength of the ancient Greek Olympic wrestler of that name—a six-time winner of the Olympic games—with the debonair charm of a WWII RAF pilot.
 More recently, Milo has been associated with the dashing Milo Ventimiglia of This Is Us fame, and it has also been the name of characters in books Catch-22 and The Phantom Tollbooth, and on screen in Milo and Otis, Alias, and Atlantis: The Lost Empire.
 Ricki Lake, Camryn Manheim, Sherry Stringfield, Liv Tyler, Craig Ferguson, and Alyssa Milano are six celebrity parents who share our enthusiasm for Milo, as do many Nameberry baby namers.
 Milo is often heard in Ireland. Milo O'Shea was a renowned Irish character actor.

Milo

The friendly and sporty feeling Nolan blends some of the best qualities of other popular boy names. With the gentle but energetic sounds of Noah, a hint of the classic Nicholas, and the cool, surname-style vibe of Greyson or Colton, it makes for a familiar and grounded choice. 
Popularized by the baseball player, Nolan Ryan, Nolan has been steadily climbing up the charts since the 1970s, and it entered the US Top 100 in 2011. While it has never been a Top 50 name, it is given to a substantial 5000 babies every year. 
Nolan is the Anglicized form of the Irish name Nuallán, meaning “noble and famous” or “champion.” 
This could give you the fun option of nickname Champ, while also providing the name with weight and history: the O’Nolans were once a chiefly Irish family, descended from the first Celts to settle in Ireland. 
A once very American feeling choice, Nolan is now more popular in France and Canada. It is on the rise in England and Wales too, a favorite in The Netherlands and Belgium, and at #22 in Hungary (albeit with the Hungarian spelling, Nolen). 
Notable Nolans include the fashion designer, Nolan Miller; the Modern Family actor, Nolan Gould; Marvel and DC voice actor, Nolan North; and the actor and singer Nolan Gerard Funk of Glee fame. Some may associate it with the Nolan Chart, a political spectrum diagram invented in the 60’s, while others may be more familiar with Nolan Chance, from the game Fortnite. 
Familiar and cool, grounded and approachable, Nolan continues to hold its steady place in the lower end of the US Top 100. 
Do you love Nolan but want some more inspiration? Other names inspired by Irish surnames include Nevan, Blaine, Riordan, Donnovan, and Callahan. For names that share a similar sound, Bowen, Milan, Noel, or Roland might appeal.

Nolan

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.
 Otis originally came into use as a tribute to the Revolutionary hero James Otis, and would be familiar to kids via the Disney film The Adventures of Milo and Otis. 
 Though well used at the turn of the last century, Otis was off the charts for two decades from 1995 to 2014, and now sounds like a fresh choice. Tobey Maguire used the name back in 2009. More recently, and possibly contributing to Otis's return to the Top 1000 in 2015, Olivia Wilde and Jason Sudeikis gave the name to their son.

Otis

Otto is cool again. Long a quintessential Old Man Name, Otto has been promoted to trending darling of adventurous baby namers. 
 Like most <a href="https://nameberry.com/baby-names/160/german-names">German names</a>, Otto fell out of favor during and after the two World Wars – it had been a Top 100 name in the years preceding. Off the Top 1000 from the mid-1970s until 2011, Otto is now headed straight uphill.
 <br/
There were some distinguished Ottos before the imperial image of Prussian Otto von Bismarck colored the name. Otto the Great is generally considered the founder of the Holy Roman Empire and there were several German and Austrian royals with the name. 

 Otto Frank was the father of Anne Frank, the young Jewish girl who wrote her famous diary during her family's years in hiding from the Nazis during World War II. She was killed in Bergen-Belsen concentration camp in 1945 and her father Otto typed and edited the diary himself to prepare it for publication. 

 Otto Hightower is a character in the Game of Thrones universe, played by Rhys Ifans in the HBO prequel House of the Dragon.

 Feminine forms of Otto include Ottoline, Ottilie, Odilia and Odette, all fashionable in the UK along with Otto itself.

Otto

Rodney peaked at Number 33 in 1965 and has been on a steady decline ever since. As its popularity history indicates, this name is more fitting for someone born in the mid-twentieth century instead of the twenty-first century. It's likely this name will continue trending downward for another generation or two before it has its chance to turn back around.
 There have been a number of famous Rodneys over the years, including comedian Rodney Dangerfield and musician Rodney Atkins.
 If looking for a way to honor a Rodney, prospective namers might consider Roderick or Rodrigo instead.

Rodney

Even less subtle than Duke or Earl, this name shot up the popularity charts in 2013, the same year young Prince George was born and the craze for all things royal (and Royal) began. Today, it's a leading boys' name on Nameberry's own popularity charts.

While Royal ranks on the US Top 1000 list for both girls and boys, It's rising precipitously for boys but softening for girls. There are currently nearly three times as many boy babies named Royal as girls..

Pop culture references: the hit Lorde song "Royals.", the Wes Anderson film The Royal Tenenbaums (in which the paterfamilias was named Royal), and most recently, the Amazon Prime series Outer Range, a supernatural neo-Western starring Josh Brolin as Royal Abbott.

The name's resemblance to the more classic Roy doesn't hurt either.

Royal

This ancient royal Scottish name had a brief vogue in midcentury America, but it would be far from a fresh choice for a baby boy now. 

Stuart

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.
 More often heard as a surname prefix (e.g. Vincent van Gogh, Dick Van Dyke), Van by itself has had some notable bearers, such as musician Van Cliburn (born Harvey Kevan) and actors Van Johnson (born Charles Van) and Van Heflin (born Emmett Evan). Because of its common connection to surnames, it makes for an interesting middle name option. Van reached as high as Number 265 in 1946.
