With many British names invading the Yankee name pool, the sophisticated Alistair could and should be part of the next wave. It debuted in the US Top 1000 in 2016. You have a triple choice with this name--the British spell it Alistair or Alastair, while the Scots prefer Alasdair--but they're all suave Gaelic versions of Alexander. Adopted by the lowland Scots by the seventeenth century, the name didn't become popular outside Scotland and Ireland until the twentieth century.
 Both Andrew Lloyd-Weber and Rod Stewart chose the Alastair spelling for their sons' names.

Alistair

Andreas is a beautiful name, with the patina of an Old Master painting, one that could make a dashing namesake for an Uncle Andrew. 
 In Europe, Andreas is currently in the Top 20 in Norway and is also popular in Denmark, Sweden, Germany, and Austria.
Some other international variations of Andrew you might want to consider — Andre, Andrei, Andres, Andrea, and Anders.
 Notable namesakes include photographer Andreas Feininger. One not-so-pleasant association: the San Andreas fault line in California.

Andreas

During its Top 10 heyday in the late 90s and early oughts, Andrew was one of the "cooler" classic boy names, an update on the old guard Roberts and Richards.
 While there are still plenty of babies named Andrew -- more than 5000 in the US last year -- it now feels more like a Dad Name than baby name. And the shamed Prince Andrew has not helped the name's image much.
 
Andrew is a variant of the Greek name Andreas, ultimately derived from the element aner, meaning "man." In the New Testament, Andrew was one of the twelve apostles and the first disciple to be called by Jesus. 
 
Although the origins of the name are Greek, Andrew is the patron saint of both Scotland and Russia, as well as Greece. It has associations with two of America's most famous artists, Wyeth and Warhol.
 
One advantage of Andrew is its host of nicknames: Andy makes it friendlier, while Drew adds to its sophistication.
 
Andrew also has several appealing foreign manifestations that are sometimes used in the U.S., including Andre (French), Andrei (Russian), Andres (Spanish), Andrea (Italian), Andreas (German, Dutch and Greek) and Anders (Norwegian and Swedish).

Andrew

This name has a nice mythological, historical, Three Musketeers-ish ring.

The origins of the name Brian are not entirely clear, but it is suspected that it evolved from an Old Celtic word related to nobility. In Ireland the name is associated with Brian Boru, the most famous of all Irish warrior-kings, credited with driving the Vikings out of Ireland around the year 1000. 
 
Like other native Irish names, Brian was outlawed in Ireland during the centuries of British rule, restored to use after the war for Irish independence in 1916. Irish immigrants propelled it onto the US Top 1000 list for the first time in 1925.
 
Because it was outlawed for so long, Brian may feel like a less classic and ancient name than it really is. Its massive popularity in the 1970s, when it ranked in the Top 10, makes it one of today's quintessential Dad Names.
 While Brian has been trending downward in the US for decades, it still ranks solidly in the Top 1000, where it will likely remain for decades to come. Bryan, Bryant, and Brianna are common variations.
 
Brian has some pretty diverse associations—to newscaster Williams, the movie Monty Python's Life of Brian and as Marilyn Manson's real name.

Brian

This appealing name of a mythical king of Tara whose reign brough prosperity to his kingdom is strongly associated with actor Sean. The Irish form is Conaire.

Benevolent name found in Israel in several forms, including Doran and Doroni.

Duncan is jaunty, confident, and open, a Scottish <a href="https://nameberry.com/list/453/royal-baby-names">royal name</a> that's brimming with friendly charm and makes it into our golden circle of names that are neither too popular nor too strange. Popularity aside, Duncan is one of the most classic <a href="https://nameberry.com/list/473/scottish-names-for-boys">Scottish names for boys</a>. 
 From a surname based on a clan name, Duncan was the name of a Scottish saint and two early Kings of the Scots. The beneficent Duncan I, who lived in the eleventh century, was immortalized in Shakespeare's Macbeth. 
 The brave and handsome Major Duncan Heyward is one of the main characters in James Fenimore Cooper's The Last of the Mohicans. Other cultural references include Duncan Idaho, the only character to appear in all of Frank Herbert's Dune novels; Duncan MacLeod, the immortal protagonist of Highlander; one of Garp's sons in The World According to Garp; and singer-songwriter Duncan Sheik.
 David Bowie's son Zowie changed his name first to Joey and then finally to Duncan.
 
Duncan peaked int he late 90s and has been a downfall since, even falling out of the Top 1000 in 2021 — but made a reappearance in 2022.

Duncan

Dustin's popularity in recent years has probably had more due to its similarity to Justin than to idolization of Dustin Hoffman -- himself named after silent screen cowboy star Dustin Farnum -- who certainly was the one to put it on the name map. In recent years, golfer Dustin Johnson has brought fresh renown to the name. Dustin is a character in Netflix hit Stranger Things. After decades in the spotlight, Dustin feels like a classic rather than an upstart. It peaked in the Top 50s in the 1980s.
 Caveat: Hoffman has confessed that his schooldays nickname was "dustbin" though in today's more tolerant naming atmosphere, Dusty may be the cute nickname.

Dustin

Ethan/Etan

A rarely used last-name-first-name, never as popular as cousins Garrett or Derek. 

Garrick

The kind of nouveau macho name favored by NRA-leaning parents. Killers' frontman Brandon Flowers gave it to his son in 2009. Gunnar is another spelling that makes the name a bit less militaristic.


Gunner

Griffin/Griffith

Isabel and Isadora are back: could it now be time for a more widespread revival of Isidore? In 2014, both Isidore and Isadore were on the list of fastest-rising names in the US.
 A common ancient Greek name belonging to several saints--including Saint Isidore the Ploughman, patron saint of Madrid and the great encyclopedist St. Isidore of Seville, whose work formed the basis of much medieval knowledge--Isidore was adopted by Spanish Jews to the point where it was almost their exclusive property.
 In addition to the obvious Izzy, another traditional nickname is Dore/Dory.

Isidore

King David's father turned 1980s cowboy, Jesse is now down in popularity. The name is associated with a wide variety of bearers, from outlaw Jesse James to Olympic athlete Jesse Owens to activist Jesse Jackson to current actors Jesse Tyler Ferguson and Jesse Eisenberg. The spelling Jesse is more usual as a <a href="https://nameberry.com/boys-names">boys' name</a> while Jessie is more traditional for girls.

Jesse

Jonathon/Jon

A name of multiple identities: a somewhat soap-operatic single-syllable surname, a homonym for the biblical bad boy Cain, and, when found in Japan and Hawaii, it transforms into the two syllable KA-neh. 

Kane also has multiple meanings: in Welsh, it's "beautiful"; in Japanese, "golden"; and in Hawaiian, "man of the Eastern sky."

Kane

For centuries this name was associated primarily with the towering figure of Italian Renaissance painter-scientist-inventor Leonardo da Vinci, and was scarcely used outside the Latin culture. 

But then along came Leonardo DiCaprio, who was supposedly given the name because his pregnant mother felt her first kick while looking at a da Vinci painting in the Ufizzi Gallery in Florence, and who would make the name young and handsome and multi-cultural. 
 Leonardo is a popular choice among other attractive Italian and <a href="https://nameberry.com/baby-names/806/spanish-names-for-boys">Spanish names for boys</a>, and its cousin Leo is popular as well.

Leonardo

This jaunty Celtic surname -- the most common family name in both Ireland and the US -- is totally viable as a first. The arguably most famous Murphy is TV's Murphy Brown, and indeed the name is twice as common for baby girls as for baby boys today. But still, it's solidly gender neutral and works equally well for all sexes. 
 There have been countless notable surnamed Murphys, including the currently prominent Eddie and Cillian. Murphy was the eponymous protagonist of Samuel Beckett's first published novel.
 One possible negative: the association with Murphy's Law--if anything can go wrong, it will.

Murphy

Matthew/Matteo/Matthias

Nathaniel was derived from the Hebrew name Netan’el, meaning "gift of God," composed of the elements natan, meaning "to give," and ’el, in reference to God. The name is featured several times in the Old and New Testaments, typically spelled Nathanael. In the New Testament, Nathanael is also known by his other name, Bartholomew.
 
Although Nathan is more popular, the more dignified Nathaniel dropped out of the Top 100 for the first time since 1977 in 2016. Despite the profusion of Nat names around, Nathaniel remains singularly appealing and distinctive, with several attractive nicknames — Nat, Natty and Nate.
 A boy named Nathaniel would have any number of real life and literary namesakes to inspire him. These include Revolutionary General Nathanael Greene, enslaved rebel Nat Turner, writers Nathaniel Hawthorne and Nathanael (born Nathan) West, lithographer Nathaniel Currier, partner of Ives, and singer/pianist Nat "King" Cole.
 An early literary character with the name is Sir Nathaniel in Shakespeare's Love's Labour's Lost. And then there was Natty Bumpo in James Fenimore Cooper's Leatherstocking Tales, Nathaniel Winkle in Dickens's The Pickwick Papers, and later Dr. Nathaniel Branden in Atlas Shrugged.
 In the realm of pop culture, we find such Nathaniels as Nate Fisher in Six Feet Under, and others in The Wire, Gossip Girl and Enchanted, as well as Pirates of the Caribbean character Nathaniel Hawk.

Oscar is one of the most stylish Old Man Names of our era. While it's softened slightly in popularity over the past 20 years, that may be considered a very good thing.
 
In the nineties and the aughties, Oscar looked to be one of the grandpa names heading straight for the top of the charts, ala Elijah or Theodore. But instead of rising into the Top 100, Oscar has settled into that comfortable place between being too far in or out.
 
Oscar has Irish and Norse roots—Norse Oscar comes from the Old English Osgar, a variation of the Old Norse name Ásgeirr. The Irish form was derived from the Gaelic elements os, meaning "deer," and car, "loving." In Irish legend, Oscar was one of the mightiest warriors of his generation, the son of Ossian and the grandson of Finn Mac Cumhaill (MacCool).
 
Oscar also has remarkable international versatility. In addition to being a top name in Sweden, where it has royal connection, Oscar ranks high on popularity lists in all the English-speaking countries as well as in France, Spain, Germany, the Netherlands, and other European and Latin American countries.
 
Actors Hugh Jackman and Gillian Anderson chose Oscar for their sons.Famous Oscars include Wilde (whose given name was Fingal), Isaac, Madison, Hammerstein, Peterson, de la Renta, the Academy Award, and the Grouch.

Oscar

Owen, a resonant Celtic name, has ranked among the Top 100 boys' names in the US for 20 years and is now at its highest point ever.
 
Why do so many parents love Owen? It's a classic with a genuine history, yet it's right in step with the modern trend for two-syllable, n-ending boys' names. Owen-like choices with less tradition behind them include Logan, Bowen, and Rowan.
 Owen is derived from two names—the Welsh Owain and the Celtic Eoghan. Each are connected to Eugene, which ultimately came from the Greek word eugenes, comprised of the elements eu, meaning good, and genes, "born." 
 
Owen became a Welsh patronymic surname during the Renaissance. The legendary St. Owen was a Benedictine monk who was a follower of St. Chad.
 
In Ireland, Owen may be spelled Eoin, as in Irish writer Eoin Colfer, and Eoghan. Other similar names include the Scottish Ewan or Euan and the French Ouen.
 
Owen's popularity now extends beyond English-speaking countries to France, Belgium, and the Netherlands.

Pronounced KILL-on, might lead a young boy astray--though that doesn't seem to have halted the progress of the popular Killian.

Quillon

Shay has an old-fashioned feel due to its association with the word for a kind of horse-drawn carriage and at the same time seems modern thanks to its simple straightforwardness.  Use Shay as a phonetic equivalent of the Irish surname Shea or the Hebrew male name Shai, or as an abbreviated form of such names as Seamus or Shane.

Sasha/Sacha

Thaddeus, a distinguished, long-neglected name, has several areas of appeal: a solid New Testament legacy, a nice antique feel, and the choice of several more modern nicknames and international variations.
 In the Bible, Thaddeus was one of the original Twelve Apostles.
 Thaddeus has made quite a few screen appearances, ranging from Spongebob Squarepants to Police Academy to Get Smart (it was the given name of the Chief) to Harry Potter. As Tadzio—the Slavic version—he played a leading role in Thomas Mann's Death in Venice.
 In real life, Thaddeus Stevens was a dominant political figure during the Civil War. Mia Farrow has a son named Thaddeus.

Theodore/Theo

Valentine/Valentin

On the rise as an independent name: Zander and Xander are both widely used can increasingly be found as characters in movies and on TV. 

Zander

Zebedee is an adorable and unusual New Testament name--which may sound like but is not a contradiction in terms. Unlike some of the longer biblical Z-names, Zebedee has a more lighthearted usability, with its gleeful ee-ending. And Zeb makes a fabulous nickname.
 In the New Testament, Zebedee plays the major role of the fisherman father of two disciples, James and John, and was with his sons mending his fishing nets when they were called by Christ.
 The name was popularized in the U.K. by a jack-in-the-box puppet named Zebedee on an early kids' TV show, The Magic Roundabout.
 Zebedee Jones is a contemporary British painter.

Zebedee

Biblical names are expanding (literally) as some parents move from Isaiah and Elijah to more elaborate choices with simple short forms, like Jedidiah and Zebediah.
 Zebediah, or Zebadiah, is the New Testament father of apostles John and James, and there are a number of Zebadiahs in the Old Testament as well.
