Callahan, the simpler spelling of Callaghan, is a rhythmic jig of a name whose history harks back to the ancient King of Munster. In the Dirty Harry movies, the Clint Eastwood character is Harry Callahan.

Callahan

Rugged but gentle at the same time, Cassian is a saintly and stylish choice that was derived from the name Cassius. Before 2017, it was an obscure choice, given to a tiny handful of boys each year. As of 2023, however, it's become one of the top ten fastest-rising names in the US, more than doubling in usage since 2022 and edging closer towards the Top 500.
 There are a number of fourth and fifth century St. Cassians, one of whom is the patron saint of stenographers (though he must not get much work these days).John Cassian was a monk and ascetic writer who introduced Eastern monasticism into the West; Cassian Elwes is a British film producer, and Patrick Wilson used the alternate spelling Kassian for his son.
 It is unlikely however, that any of these can be credited for the rise of Cassian. Instead, we must turn to pop culture.
 In 2016, just before Cassian began to climb the charts, the Star Wars Franchise movie, Rogue One, was released and included a character called Cassian Andor, who then went on to feature as the lead in the television spinoff series, Andor. With the sounds of popular Julian, Jasper, and Adrian, like Casper but not too ghostly, Cassian caught people's attention, not just in the US, but in the UK, where it now ranks in the Top 600.
 
But what caused the even bigger leap up the charts in 2023? Again, we must look towards a fictional character. The popular romance-fantasy book series A Court of Thorns and Roses by Sarah J. Maas features a Cassian, and the latest novel included a Cassian storyline that likely put the name on people's radar. "ACOTAR" as it gets called is popular on BookTok and BookTube so it's no wonder parents are taking inspiration from it. 
 Similar to Nameberry favorite Caspian with sounds that are both strong and soft, both ancient and right up to date, Cassian is a hot name right now, and was given to more than 550 babies in 2023.

Cassian

Clement, the name of fourteen popes and several saints, has a pleasantly, positive, slightly antiquated feel, like the phrase "clement weather." 
 Clement C. Moore wrote the poem "A Visit from St. Nicholas," Clement Attlee was a prominent post-World War II British Prime Minister, and Clement Greenberg was the art critic who promoted Abstract Expressionism.
 The hero of Thomas Hardy's The Return of the Native is Clement Yeobright, known as Clym rather than the usual Clem.

Clement

This rhythmic last-name-first-name projects the creativity and inventiveness of Thomas Edison. It's an English surname deriving from either Adam or Eda, a medieval diminutive of Edith.

 Q. Why is it suddenly being considered by new parents? A) They may possibly be inspired by the mega-trendy Addison, or B) infuenced by the renewed interest in "Twilight" hero Edward and looking at other Ed-starting possibilities, C) attracted to the stylish -son ending, ala Jackson and Harrison or D) into science.

 Whatever the reason, Edison is rising through the ranks and strikes the perfect balance of familiar and distinctive.

Strong, charismatic, and sleek, Elias has followed in the footsteps of Elijah and Eli to become a popular choice among parents today. 
While it may sound cool and fresh, Elias is a name with history and substance. It is the Greek form of the name Elijah, meaning “Yahweh is God,” and was used in both the Greek New Testament and medieval tales. Elias was then given to early saints, to honor the miracles and work of the popular Biblical figure. 
Revived by Puritans in the 18th century, notable namesakes include the inventor of the sewing machine, Elias Howe, writer Elias Canetti and Walter Elias Disney. 
Felix Mendelssohn composed a popular oratorio named “Elias”, while Sir Walter Scott, Anthony Trollope, and Thomas Hardy all have characters called Elias in their novels, giving the name literary and classical charm. 
In the US, Elias has seen significant usage from the 90’s onwards with its popularity doubling during the 2010’s. Given to over 6000 boys each year, Elias continues to climb the charts and has overtaken Eli as a go to El- choice. 
While still outranked by Elijah in the US, across Europe and South America, Elias is the preferred form. Popular in Sweden, Germany, Switzerland, Uruguay, and Mexico, Elias travels well. 
The name has been chosen for characters in the popular horror podcast, The Magnus Archives, Cassandra Clare’s trilogy “The Infernal Devices”, and the TV series “Person of Interest.” Elias has the celebrity seal of approval too, with singer Michael Bublé, actor Robert Downey Jr, tennis player Boris Becker and actress Barbara Becker choosing to use it for their sons. 
Handsome and refined as it is, the main problem with Elias is deciding whether you want to use it, or keep Elijah, Eli, Elliot, Elio, Eliza, Elizabeth, or Elise in the running. To avoid the problem, you could go with similar but lower ranking Tobias, Linus, or Ozias.

Elias

Elliot (which boasts several spellings depending upon how many 'l's or 't's you want to use) is a winner -- it has the ideal quality of being neither too common nor weirdly unique. Elliot had a style boost back in the early 1980s via the young hero of the movie E.T. , who was named Elliot. Since then there have been Elliots on Law & Order: SVU and Mad Men.
 Elliott namesakes include composer Carter, actor Gould, and photographer Erwitt.

Elliot

If you're looking for a Welsh name less common than Dylan, Griffin, Evan, or Morgan, you might want to consider this offbeat epithet of the wise wizard Merlin. 

Root name Ambrose is an ancient saints' name derived from the Greek ambrosia, the food and drink of the gods that conferred immortality.

Emrys

Finnian is a fair jig of a name, energetic and easy on the ear. Finnian (and brother Finian) is also familiar in its alternate spelling through the classic 1968 Broadway musical Finian's Rainbow, later made into a film starring Fred Astaire as Finian McLonergan.
 There is also a St. Finnian who was a famous teacher and scholar.
 We think Finnian/Finian could really catch on in the wake of cousins Finn and Finlay/Finley.

Finnian

Frederick, and friendlier nickname Fred, seemed almost to have disappeared, leaving just the memory of Freds past such as Astaire, Mr. Rogers and Flintstone. But today's parents are beginning to recognize it as a strong classic and one of the top <a href="https://nameberry.com/list/341/royal-names-for-boys">royal baby boy names</a>.
 Previously, Frederick had taken on a rather forbidding, foreign, military air, reminiscent of Frederick the Great, the enlightened king of Prussia who laid the foundations of the powerful Prussian empire.
 For African-Americans, Frederick can be seen as a hero name, honoring Frederick Douglass, who rose from slavery to power as a political activist.
 Frederick appears as a character in Shakespeare's As You Like It and the novels of, among others, Jane Austen and Henry James.
The name is often streamlined to Frederic and even Fredric. And if you don't like Fred or Freddie (though we do), another nickname is Fritz.
 Federico is the appealing Italian and Spanish form, as in renowned poet Federico Garcia Lorca.

Frederick

Gabriel has become a biblical favorite, an angelic choice that's lighter and less patriarchal than some of his Old Testament brethren. Derived from the Hebrew name Gavri’el, Gabriel is taken from the elements gever, meaning "strong," and ’el, in reference to God.
 
In Abrahamic religions, Gabriel is the archangel who heralded the news of Jesus' birth, and appears in Christian, Jewish and Muslim texts. He presides over Paradise, serving as the angel of mercy, life, joy, judgment, truth and dreams. 
 In addition to all his other responsibilities, Gabriel is the patron saint of broadcasters and diplomats, and he governs Mondays and the month of January, making Gabriel one of the top <a href="https://nameberry.com/list/629/71-wonderful-names-for-january-babies">January baby names</a>. 
 
Gabriel has proven itself a friendly and appealing alternative to Michael, that other, long-reigning archangel. Gabriel enjoys remarkable international popularity, ranking in the Top 100 in countries as diverse as Israel and Iceland, Chile and Croatia. It is currently the Number 1 boys' name in France.
 Parents of Gabriels of varying ages include Mick Jagger and Jerry Hall, Daniel Day-Lewis and Isabelle Adjani, Jason Alexander, Meredith Vieira, and Mia Farrow.

Gabriel

Considered ultra debonair in the silent-movie era, Gilbert then went through a nerdy phase, a la Gilbert Gottfried. Now though, like Albert and Alfred and Walter and Frank, it could be in for a style revival. 
 Gilbert has always been on the US popularity list, reaching as high as Number 90 in 1930. The Normans introduced Gilbert to England, where it was common during the Middle Ages; it was the name of a 12th century English saint.
 Gilberts have appeared in such books as Henry James's Portrait of a Lady, Lucy Maud Montgomery's Anne of Green Gables, and Ayn Rand's Atlas Shrugged, and on screen in The Incredibles and as embodied by the young Johnny Depp in What's Eating Gilbert Grape?. The most famous portrait painter of George Washington was Gilbert Stuart. 
 Nickname Gil could come back along with Hal, but even more appealing are Gib or Gibby.

Gilbert

Henry is back. The classic Henry climbed back onto the Top 10 in the US in 2021 for the first time in over a century, and now stands at Number 7.
 Like James and Theodore, Henry is a traditional name that also manages to feel stylish. Despite its popularity, it's not for everyone, but in some upscale American suburbs, it can seem as if every other little boy is named Henry or Theo or Jack.
 Henry was derived from the French Henri, which ultimately comes from the Germanic name Heimrich, made up of the components heim, meaning "home" or "estate," and rich, meaning "ruler." The most famous bearer is Henry VIII of England, best known for having six wives—two of whom he beheaded for not bearing him sons. It’s been used in the British royal family many times since, including for the current prince better known as Harry.
 
Other illustrious Henrys that might provide baby name inspiration include Henry David Thoreau, Henry (Hank) Aaron, Henry James, Henry Ford and Henry Miller.
 Numerous celebs have chosen Henry for their sons, from Julia Roberts to Minnie Driver to Heidi Klum to Colin Farrell.
 Appealing international versions include Arrigo, Enrico, Enzio and Enrique.

Henry

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

Jeremiah is a solid Old Testament prophet name that has gradually taken the place of the now dated Jeremy, Gerard and Gerald, joining other currently popular biblical 'iah' names like Josiah and Isaiah. In the Bible Jeremiah is a famous prophet whose story is recorded in the book named after him.
 Dickens used the name in two of his novels--Little Dorrit and A Tale of Two Cities-- and other fictional Jeremiahs have been spotted in such movies and TV shows as Oz, Zoey101 and The Princess Diaries. Leonard Bernstein composed a work called Jeremiah Symphony.
 Caveats: Once-logical nickname Jerry sounds like the family dentist, and some may make the Jeremiah bullfrog association.
 A related, more unusual biblical option: Jeriah.

Jeremiah

Jonah, the name of the Old Testament prophet who was swallowed by the whale, only to emerge unharmed three days later, is increasingly appreciated by parents looking for a biblical name less common than Jacob or Joshua, yet not too obscure. Plus, Jonah comes with a ready-made nursery-decorating motif.
 The appealing Jonah has been featured in such movies as Sleepless in Seattle and Knocked Up and is currently represented by actor/writer Jonah Hill.
 Jonas is the Greek version and Yona is a female spin.

Jonah

Lawrence is the dominant spelling in the US, but in the UK Laurence and Lawrence are given in almost equal numbers each year, often with the adorable nickname Laurie or Lawrie. British actor Sir Laurence Olivier is a famous bearer.

 There have been several saints with the name Laurence, which account for its historic popularity in the Christian world. Nowadays, it's an underused classic with a warm, distinguished appeal.

Laurence

Sophisticated Gallic version of Lucian, Lucien may appeal to parents attracted to this meaning over that of Lucas and Luke, which have a different root, and also looking for a more unusual choice. Lucien joined the US Top 1000 for the first time in 2023, given to over 200 baby boys.

Lucien

Orion is a rising star, with both mythical and celestial overtones.
 The Greek mythological Orion was the legendary hunter who pursued the seven daughters of Atlas, was slain by the goddess Artemis, and then placed as one of the brightest constellations in the night sky by Zeus.
 Mark Twain had a brother named Orion, and Chris "Big" Noth picked the name for his son. It is also a Harry Potter name.
 Orion's Gaelic connection to O'Ryan/Ryan makes it familiar as well as unusual.

Orion

Patrick, long tied to a hyper-Irish image, is enjoying something of a renaissance as a stylish classic, as it has long been considered in England. Along with such choices as Charles and George, Patrick has escaped overuse in recent decades.
 Why has Patrick slipped from its high of Number 30 in the 1960s? Partly to blame might be its androgynous nicknames, Pat and Patsy. But with more and more parents calling their sons by their full names, this becomes less of an issue.
 An American hero name via Patrick ("Give me liberty or give me death") Henry, there are also a number of more recent noteworthy Patricks, including Ewing, Swayze, Dempsey, Buchanan, Stewart and Wilson. And Patrick is still a recent presence on such shows as The Mentalist and Desperate Housewives.
 You also may want to consider the name's native version, Padraig, which was used for his son by Patrick Ewing, or a European version such as Patrice (French), Patrizio (Italian) or Patricio (Spanish).
 Saint Patrick is the patron saint of Ireland, credited with converting his people to Christianity in the fifth century, which would give a son with this name a widely -- and raucously -- celebrated holiday.

Patrick

With the prevailing popularity of Samuel, some parents are considering this more (literally) powerful biblical name, which shares the desirable nickname of Sam.
 Samson was, of course, the supernaturally strong champion of the Israelites against the Philistines who was betrayed by Delilah, as dramatized in more than one technicolor epic. But the more it is used for children today, the more the name is able to move away from that image.
Sampson is a variant spelling--Sampson Brass is a character in the Dickens novel The Old Curiosity Shop, Samzun is the interesting Celtic spelling, Sansone the Italian version.
 The story of Samson has been translated into a number of works of art, including Milton's poetic drama Samson Agonistes, an oratorio by Handel, an opera by Saint-Saens, and paintings by Rembrandt and Rubens.

Samson

St. Senan was a famed founder of monasteries, whose ruins can still be seen. Legend has it that before he could found it, he had to banish a great monster.  Other versions are Sionan, Sinan, Synan and Sinon. Seanan is also a pet form of Sean.

Senan

Sleek and smart, with a hint of mystique about it, Silas is a recent addition to the US Top 100. Both mythological and Biblical in origin, Silas joins the ranks of Isaiah, Atlas, Elias, and Sebastian: polished and contemporary feeling names with plenty of history. 
The origins of Silas are debated or perhaps multiple. On one hand, it could a simplified form of the Latin Silvanus, meaning “of the forest.” 
In Roman mythology, Silvanus was the god of trees, and his name was originally bestowed on those who lived in forested areas or who worked with wood. This could bring either a hardy, outdoorsy ruggedness to the name or something more mystical, dark, and intriguing. 
On the other hand, Silas could be a Greek form of the Aramaic Seila or of the Hebrew Saul, meaning “asked for” or “prayed for”. 
Its Biblical roots can then be traced to either Saul, the first King of Israel, or to a companion of Paul the Apostle. Later venerated as a saint, Silas was a leading member of the early Christian community, who accompanied Paul on his second missionary journey. 
Given as an English name from the 17th century onwards, Silas has a rich literary history. Notably used by George Eliot in Silas Marner and by Dan Brown in The Da Vinci Code, Sheridan Le Fanu, Charles Dickens, Robert Frost, Willaim D. Howell, Neil Gaiman, and Mark Twain have also featured a Silas in their work. 
A longstanding favorite and <a href=“https://nameberry.com/popular-names/nameberry/boys”>one of the most searched names on Nameberry</a>, in the ‘real world’, Silas had mostly lingered towards the lower end of the US Top 1000 in the 20th century. 
It did gain some attention in the Netherlands, Denmark, and Switzerland in the 2000’s, but it took until the 2010’s for it to make significant moves in the US. Now, it is trending upwards and given to nearly 4000 babies each year. 
Based on its Nameberry popularity, its status as ancient but still fresh, and its similarity in sound or style to popular Elijah, Isaac, Lucas, and Samuel, Silas could continue to climb the charts. 
If you love it, but don’t want to be part of the crowd, you could consider one of Silas’s relatives, such as Sylvan, Sylvester, or Sylvius; alternatively, Linus, Rufus, Caius, Laurence, or Ozias might appeal as less popular options.

Silas

Sonny is one of the generic boy nickname names making a surprise reappearance, and it was recently used by actor Jason Lee. Another surprise: It's been on the US Top 1000 list every year since 1927, reaching a peak in 1975, when it hit Number 428.
 Most celebrities who've gone by Sonny have had a formal birth name, including Sonny Bono (born Salvatore), Secretary of Agriculture Sonny Purdue (George Ervin), boxer Sonny Liston (Charles), and jazz musician Sonny Rollins (Theodore Walter). Even fictional Sonny Crockett on Miami Vice was born James.

Sonny

Reminiscent of the Old West, with rugged charm and a gentle, easy-going feel, Wesley has long been a staple on the US charts. 
Its popularity may have peaked in the 1970s when it reached #66, but Wesley has never really gone out of style. It’s always remained inside the US Top 200, making it a modern classic, solid and familiar but not too overused. 
Now, Wesley is receiving renewed interest, joining Wyatt, Waylon, Maverick, Weston and Beau in the Top 100, as parents turn towards surnames-as-given-names and to names that feel both preppy and cowboyish. 
Derived from an English surname – which likely came from an English place name – Wesley means “western meadow” or “western clearing.” It was first used as a given name in the 1700’s, when parents chose it in honor of John Wesley, the founder of Methodism. 
Wesley’s popularity has spread since then and it’s no longer tied to these religious associations. Instead, it has a number of other noteworthy bearers, including: the military general and politician, Wesley Clark; the actor, Wesley Snipes; the film directors, Wes Anderson and Wes Craven; the jazz guitarist, Wes Montgomery; and TV personality, Wes Nelson. 
The name might also be remembered by the fans of several TV classics, including “Star Trek: The Next Generation”, “Buffy the Vampire Slayer”, and “Last of the Summer Wine,” all of which have featured a fictional Wesley. 
Despite these notable namesakes, Wesley is currently only popular in the US. Though it has seen some usage in England, Wales, and France in recent years, it has yet to move into the spotlight. 
Handsome and charming, Wesley is given to more than 4000 boys each year in the US, and following its recent trajectory, it could well move further up the charts. If you’re wanting to avoid a popular choice but love Wesley, the similar Westley ranks much lower. You could also consider Casey, Halston, Dempsey, or Layton.
