Aiden in all its spelling variations is the Anglicized version of the Irish Aodhán, which was originally a pet form of the Irish name Aodh (pronounced 'ee'), who was the old Celtic god of the sun and fire. St. Aidan was a famous seventh century Irish saint, noted for his kindness and generosity and for spreading Christianity.
 
Aiden has been a spectacular name success story—especially if you add all its various spellings together. Counted together, Aiden in all its versions is still a Top 10 boys' name.
 
The Aiden spelling has become the predominant version of the name in the US, followed by Ayden -- and then, in order of popularity, Aidan, Adan, Aden, Aydin, Aydan, Eiden, Aidyn, Eydan, Eyden, Adin, Aedan, and Aiyden. And then there's a pack of popular rhyming offshoots such as Brayden and Kaden.
 
Irish actor Aidan Quinn introduced the name to the US. The Aiden spelling was used by actress Tracey Gold and Rod Stewart for their sons.

Aiden

Bram has an unusual measure of character and charm for a one-syllable name; it started as a hipper-than-Abe diminutive of the biblical Abraham, but is also an independent Irish and Dutch name, made famous by Irish-born Dracula creator Bram (nee Abraham) Stoker. Bram is currently Number 16 in the Netherlands; Bram Howard was a character on The West Wing.
 Another route to Bram is Bramwell, as in early actor Bramwell Fletcher, who &mdash; speaking of horror movies &mdash; was noted for his mad scenes in the 1932 film The Mummy.

Bram

Callum, a charming Scottish name high on the list in England, Scotland and Northern Ireland, is rising through the ranks in the US now too. And it comes complete with the easy nickname Cal. Kyle MacLachlan chose Callum for his son. Callum might also be spelled Calum; in Ireland, the name became Colm, and in Scotland it's sometimes used as a pet form of Malcolm.
 
Callum was derived from Latin Columba, a unisex given name meaning "dove." Callum was popular among early Christians because the dove was a symbol of purity, peace and the Holy Spirit. St. Columba was one of the most influential of the early Celtic saints.

Callum

Cillian is one of the native Irish names that, along with Aiden and Declan, is becoming an unlikely favorite in contemporary America. The Killian spelling has been more popular in the US, but Cillian's star is rising, perhaps thanks to Irish actor Cillian Murphy, star of Oppenheimer and Peaky Blinders.
 There are several Saint Cillians, including one who was sent to Bavaria to convert the natives and was martyred for his trouble. 
 Patrick Woulfe, a Catholic priest who was instrumental in reviving native Irish names in that country after the war for independence from England in the 1920s, theorized that Cillian might also be related to a Gaelic name meaning war.

Cillian

Declan is the Anglicized form of the Irish name Deaglán. St. Declan was one of the first missionaries to bring Christianity to Ireland, preceding St. Patrick. Originally from Wales, he founded the monastery of Ardmore in Ireland.
 
Declan, the amiable and appealing name of an Irish saint (and the real first name of singer Elvis Costello), is very popular in the Emerald Isle and beginning its certain climb to popularity here, after debuting on the American list in 1998. Like Aidan and Liam, Declan is shaping up to be an American hit.
 
Declan Porter is a current character on Revenge. 
 Cyndi Lauper spelled her son's name Declyn.

Declan

A less common — and biblical — alternative to Liam. Eliam joined the Top 1000 for the first time in 2021. In Puerto Rico, it's a Top 50 choice.

Evan has a mellow nice-guy image that has kept it popular, while it has been widely used in Wales since the nineteenth century. And interestingly—and surprisingly—enough, Evan charts highly for boys in France.
 Evan was derived from Iefan, a Welsh version of John. John is ultimately a derivative of the Hebrew name Yochanan, comprised of the elements yo, meaning "God" and chanan, "to be gracious." Evan is actually a Hebrew word itself, meaning "rock."
 
Jenny McCarthy has a son named Evan, and some other modern associations are former Senator Evan Bayh, novelist Evan Hunter, and the movie Evan Almighty. It is also sometimes used for girls, as in actress Evan Rachel Wood.

Evan

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.

J. R. R. Tolkien introduced a plethora of new names into the world, but this is one character name that never caught on, nor will it likely ever.

Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular <a href="https://nameberry.com/search/boys-names/j">boy names starting with J</a>. 
Jack is a derivative of John that originated in medieval England. The name went from John to Johnkin to Jankin to Jackin to Jack. The name was so common in the Middle Ages that Jack became a generic term for a man. 
 
Jack is familiar to all from earliest childhood via Jack and Jill, Jack Sprat, Jack and the Beanstalk and Little Jack Horner et al. It is still a recent favorite for novel, TV and movie characters. 
 
Jack is at the top of the charts in Ireland and Scotland, and also ranks highly in Germany, Sweden, the Netherlands, and Belgium.
 
The jaunty Scottish version is Jock.

Jack

Definite twenty-first- century possibilities, with its stylish K opening, strong first syllable, and softer second.

A growing number of high-profile (and other) parents are choosing to honor their musical idols, such as Hendrix, Presley, Jagger, and now Lennon. Lennon first came to notice when Liam Gallagher and Patsy Kensit used it for their son in 1999, and singer-musician Adam Pascal followed their lead in two years later. Thanks in part to female singer and actress Lennon Stella, it's now more popular for girls than for boys.
 Lennon made it onto the popularity list in 2008. 
 In addition to its obvious Beatles connection, Lennon has a nice lemony feel.

Lennon

Leo is a strong-yet-friendly name that was common among the Romans, used for thirteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

Derived from the Latin meaning "lion", Leo is one of those names, like Luke and Finn, that many people assume must be short for something but that is authentically a complete name in its own right. That said, Leo can but short for any number of names, from Leonardo in Latinate languages to Leon and Leopold in Germanic languages. We've even heard of little girl Leonoras and Leonies called Leo: How cute is that?

Leo's simplicity makes it an international star, ranking in the Top 100 in countries as diverse as Ireland and Israel, Spain and Sweden, Austria and Australia. Leo is a truly diverse name, a perfect choice for any family crossing countries or blending cultures.
 
Leo's only real downside is its universal popularity and familiarity. If you call your child Leo, you and they will almost certainly encounter many other Leos over the years of all types and ages. Plus or minus? Or both?
 
Penelope Cruz and Javier Bardem called their son Leo, as did actress Kim Raver, NASCAR driver Jeff Gordon and Kristin Olson. 
 Famous Leos of the past include Pope Leo the Great, a number of early saints, and Leo Tolstoy, as well as Dead End Kid Gorcey, colorful baseball manager Durocher, influential gallerist Castelli and the leonine MGM icon. There have been Leos seen on everything from The West Wing to Charmed to Grey's Anatomy to Seinfeld's Uncle Leo.

Levi, lighter and more energetic than most biblical names, with its up vowel ending, combines Old Testament gravitas with the casual flair associated with Levi Strauss jeans. 
 Now it's being rediscovered in a major way—Levi has been shooting up the charts in recent years. Extremely popular in the US, it's also a Top 100 name throughout the English-speaking world as well as in a diverse range of countries from Germany to Brazil.
 
In the Old Testament, Levi was the third son of Leah and Jacob, from whom the priestly tribe of Levites descended; in the New Testament, Levi was Matthew's given name before he became an apostle. It is suspected that Levi derives from the Hebrew word yillaweh, meaning "he will join." 
 Levi received a lot of attention as the sons of Matthew McConaughey, Sheryl Crow and Sara Gilbert.
 In the Thomas Hardy novel Far from the Madding Crowd, Levi Everdene is the father of the heroine.

Levon is a related name.

This short form of Elias is gaining traction in Sweden, it’s culture of origin. The trendy S-ending and similarity to Liam make Lias a gem of an international boy name.

Lias

Stylish Hebrew name with potential to catch on more in the wake of Logan, Liam, Lochlan, Lincoln et al.

Liron

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

Lorcan is a name rich in Irish history as belonging to several kings, including the grandfather of the most famous high king of Ireland, Brian Boru. Lorcan O'Toole, known in English as Laurence O'Toole, is the patron saint of Dublin, so it's not too surprising that Irish-born actor Peter O'Toole named his son Lorcan.
 In the Harry Potter epic, Lorcan is the twin son of Luna Lovegood Scamander.
 Strong, easy to pronounce and spell, Lorcan is an Irish name that would stand out from the more common crop of Connors and Liams.

Lorcan

Lucan is a rarely heard Irish name, a Luke form with the trendy an ending. 

Lucan

Lucas is a Top 10 boys' name with a slightly-less-popular almost-identical twin brother, Luke. Like Elijah and Elias, Lucas and Luke come from the same root and have the same meaning and so feel even more popular than they are.
 
The Latin derivation of the Greek Loukas, the name's meaning references Lucania, an ancient territory in Southern Italy. Along with Luke, Lucas is also related to international name star Luca, while the similar Lucius and Lucian derive from a different root and have a different meaning.
 Lucas is enjoying tremendous international success, popular throughout the English-speaking world as well as in a diverse range of countries throughout Europe and Latin America, including Scandinavia, France, Germany, Spain, and Brazil. This makes Lucas the perfect choice for a cross-cultural family.
 Lucas has long been a favorite of TV scriptwriters, from the early black-and-white days of The Rifleman (Chuck Connors as Lucas McCain) to the schoolteacher series Lucas Tanner to the more contemporary One Tree Hill. On the literary side, the name appears as Lucas Beauchamp in William Faulkner's Intruder in the Dust and Light in August.
 Lucas Cranach was an important German Renaissance painter and printmaker; Lucas Samaras is an eccentric Greek-born American contemporary artist. Some will associate the name with director George Lucas.

Lucas

Lumen is a Latin word meaning "light", and the term used for the measurement of light output (making it an attractive choice for science-buffs). 
The name was used for a female character in the TV series Dexter (played by Julia Stiles), and a real-life bearer is the American (male) artist Lumen Martin Winter.

Lumen

Also spelt Loomis, this locational English surname comes from Lomax (Lumhalghs), near Bury in Lancashire. Beyoncé's maternal grandfather, Lumis Albert Beyincé, is a notable bearer of the name.

Lumis

Malcolm is a warm and welcoming Scottish appellation (originally Mael-Colium) that fits into that golden circle of names that are distinctive but not at all odd. A royal name in Scotland, Malcolm is also a hero name for many via radical civil rights activist Malcolm X. 
 Malcolm was the name of four Scottish kings — including the son of Duncan who succeeded to the throne after Macbeth murdered his father — and has been a standard in that country.
 Denzel Washington named one of his sons Malcolm, as did Harrison Ford.
 Actor Malcolm McDowell is one current bearer. Other namesakes are writer Lowry; bestselling author and trendspotter Gladwell; Sex Pistols musician McLaren; and actor Jamal Warner. There have also been several Malcolms on TV — e.g., in Malcolm in the Middle, Firefly and in the Outlander series. There were no fewer than three characters named Malcolm in the Harry Potter books.

With Liam at the top of the boys' popularity list, parents might discover the still-rare Niam. This is one of the unknown but plausible <a href="https://nameberry.com/search/boys-names/n">boy names starting with N</a>.

The short, cute Pim is a Top 100 boys' name in The Netherlands though little-known outside that country.  But in a family overrun with Williams, Pim could make an original nickname setting a modern child apart from father Will and grandpa Bill.

A really unusual choice that could be used to honor Grandpa Will. 

Quilliam

Quinn is an engaging Celtic surname that is still on the rise for girls but beginning to flag for boys. As a female name, Quinn is in the Top 100, used for over 3000 baby girls last year, but toward the bottom of the Top 500 for boys, given to 700 baby boys.
Pop culture was an important influence on Quinn's popularity for both genders. Quinn started leaning decidedly toward the feminine thanks to a female cheerleader character on the television show Glee. For boys, Quinn's popularity was influenced by "The Mighty Quinn," the name of a movie, a band, and a Bob Dylan song. 
 Sharon Stone has a son named Quinn. Other ideas for boyish names like Quinn: Quinton, Quincy, Finn.

Quinn

Ryan’s use as a given name was inspired by the surname Ryan, a variation of the Irish O’Riain meaning "son of Rían." Rían is composed of the Irish-Gaelic elements rí, meaning "king" and an, a diminutive suffix. Ryan is considered a unisex name in the US, where variant spellings Ryann and Ryanne are also valid for girls.
 
Ryan has been one of the most popular <a href="https://nameberry.com/baby-names/168/irish-names">Irish names</a> in America for decades; it had been in the Top 20 since 1976, and dropped out in 2010 but still ranks highly, even though parents now have such a wide choice of Irish surnames, from Flynn to Finnigan, and newer Ry names like Ryder. Ryan (born Patrick) O'Neal first brought it to light in the mid-1960s, when parents saw it as a fresher and more spirited alternative to names like Brian and Kevin. In recent years, Ryan has taken off as a girl's name.
 Several male marquee Ryans still keep the name in the spotlight—think Ryan Seacrest, Ryan Reynolds, Ryan Gosling and Ryan Philippe.

Ryan

Sam has long been used on its own for boys, as accepted standing by itself as it is as a short form of Samuel. Straightforward and down-to-earth, Sam is the name of the son of the co-stars of The Americans, Keri Russell and Matthew Rhys.

Sam is one of the most popular <a href="https://nameberry.com/search/baby-names-starting-with/s">names that start with S</a> in the Western world, ranking higher in several European countries than it does in the US, where it's trended downward since the 19th century, though it's always been in the Top 1000.

Tilian

A contemporary reconfiguration of Tyler, although perhaps too close to Tylenol to warrant greater popularity.

Tylen

Will has definitely replaced Bill, not only as a nickname for William but as a stand-alone name as well, partly thanks to England's Prince William, also known as Wills.
 Will has a nice old-fashioned, down-home charm, and with recent references such as Will Smith, Good Will Hunting, and Will and Grace, it has taken on an air of understated cool.
 Most celebrities known as Will were christened William—Shakespeare, legendary humorist Rogers, cartoonist Eisner, and actor Arnett—but others were not. Will Smith was born Willard and Will Ferrell was originally John William.
 A key character on Glee was Will Schuester.

Will

William is one of the most enduring of classic names for boys. It's also among the most popular boys' names, as American parents see it as being ideally conservative yet contemporary, and hands-down the most popular <a href="https://nameberry.com/search/boys-names/w">baby name beginning with W</a> of all time. 
 For 400 years, William has been second only to John as the most popular name in the English-speaking world. And now of course, it's also a newsy name—thanks to Britain's high-profile Prince William.
 William is derived from the Germanic name Wilhelm, composed of the elements wil, "will," and helm, referring to a helmet or protection. The name was introduced to England by William the Conqueror, with William being the Norman variation of the name. In Central and Southern France, it was translated as Guillaume.
 
In terms of short forms, yesterday's Bills and Billys have given way to today's Wills—or Williams, with no diminutive—though a few hip Billys, including Helena Bonham Carter and Tim Burton's, have surfaced recently. 
 But Irish spinoff Liam is the most stylish William nickname and has now superseded William, becoming the most popular boy name in America. Riding the William bandwagon is the Dutch Willem, which comes with the unique nickname Pim.
 
William has long reigned as a royal name in the U.K. There are tons of worthy namesakes called William, including William Shakespeare, Bill Gates and four U.S. presidents.

William

Sounds like the name of a new synthetic fabric. 

Xylon

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.
