Ben, the diminutive of Benjamin or Benedict, can easily stand on its own as a simple, strong, nice-guy choice, though it's somewhat attenuated. Ben is this generation's Bob or Bill. 

Boone is one of the advancing herd of lean and lanky cowboy names with a laid-back, backwoods, Western feel—and surprising French roots. It's inevitably linked with legendary frontiersman Daniel, and also with the positive connotations of the word boon. It debuted in the US Top 1000 in 2015.
 T. (for Thomas) Boone Pickens is a high-profile business magnate; Boone Carlyle was a fiery character on TV's Lost.

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.

Cesare

Dramatic and worldly, Cosimo was chosen by singer Beck and his wife, Marissa Ribisi, for their son. Now that Cosima has emerged as a starbaby favorite, twin brother Cosimo could join her.
 Cosimo de Medici was the first of the Medici dynasty to wield power in Florence during much of the Italian Renaissance and was noted for his patronage of the arts. An inspirational name for creative parents.

Cosimo

Though closely associated with the great medieval Florentine poet Dante Alighieri -- who's so famous most people skip the last name -- it's not as much of a one-man name as you might think. Heck, it's not even a one-poet name, thanks to British pre-Rapahaelite Dante Gabriel Rosetti. Though especially well used in the Italian-American community, it would make a striking name for any little boy.

Dante

This cross-cultural name, found in Wales, Brittany, and Spain, is a surprise star in the U.S. in recent years, largely thanks to actor Gael Garcia Bernal. It's especially popular in Texas.

Gael

Iconoclasts though we may be, we like Fred, we like Frank, and we like George, which was among the Top 10 from 1830 to 1950, when the number of little Georges started to decline. Solid, strong, royal and saintly, yet friendly and unpretentious, we think that George is in prime position for a comeback, especially since it was chosen by Britain's royal couple.
 George was the name of the king of Britain for 116 straight years, as well as the patron saint of England (Saint George), who slayed the dragon and became a symbol of good conquering evil. America's most famous George is, of course, Washington, the Father of Our Country.
 Just a few of the many many possible namesakes are George Handel, Shaw, Bush, Gershwin, Burns, Clooney, Shearing, Steinbrenner, Stephanopoulos, Harrison, Orwell, McGovern, Lucas and Clooney.
 Celebrities who have chosen George for their sons include Kristin Scott Thomas, Jane Kaczmarek and Eva Herzigova. George Forman named all five of his sons George.
 Not surprisingly, there are Georges scattered through English and American literature, including in two Jane Austen novels, and in Vanity Fair, Uncle Tom's Cabin and An American Tragedy, not to mention Curious George, "George of the Jungle," George Jetson, George Jefferson, George Bailey and George Costanza.

George

Humphrey is an old name that might have faded completely were it not for that Bogie flair. A royal name in Britain, where it's used somewhat more frequently, Humphrey might just have some life beyond Bogart here, especially with the recent interest in the names of Golden Age Hollywood stars. His first name was the maiden name of his mother, Maud Humphrey, a well-known illustrator who used baby H. as a model.
 Humphrey was brought to England by the Normans and was made famous by Duke Humphrey, the fifteenth century Duke of Gloucester and youngest son of Henry IV, a noted patron of literature, who appears in Shakespeare's Henry IV. In other literature, Humphrey Wasp is a character in Ben Jonson's Bartholomew Fair, and the eponymous hero of Tobias Smollett's early novel Humphrey Clinker. In James Joyce's Finnegans Wake Humphrey Climpden Earwicker represents the everyman.
 Bottom line: An interesting name with a noirish edge.

Humphrey

Ian is Scottish form of John, derived from the Hebrew name Yohanan. It is an Anglicization of the Scottish Gaelic Iain, which is also a viable spelling. Ian was introduced to Americans by Ian Fleming, creator of James Bond.
 
Ian was rather late making inroads on our shores—it was already the seventh most popular name in England in 1975. It’s been on a steady path in the Top 100 ever since the introduction of James Bond, thanks to its jaunty charm. Today, Ian flies in formation with fellow classic British RAF pilot names, like Derek and Miles and Colin, all now certified U.S. citizens, packing considerable punch and panache into its three short letters. So though it may not be the newest name on the block, it's still a recommended choice. 
 
Notable namesakes include actor Ian McKellan and novelist Ian McEwan. Actor Ian Ziering pronounces his name EYE-an, rather than the traditional EE-an.

Isaac has shaved off his biblical beard and leaped into the upper echelon of popular boys' names, outrunning cousin Isaiah. A favorite of the Puritans, Isaac has never dipped below Number 400 on the US list of top boy names.
 Isaac evolved from the name Yitzchaq, derived from the Hebrew word tzachaq, meaning "to laugh." In the Old Testament, Isaac was the long-awaited son of the elderly Sarah and 100-year-old Abraham, so old that their news provoked laughter, giving the name its meaning. Isaac is used as a given name among Jews, Christians, and Muslims alike.
 
A baby given this name can point to many distinguished namesakes, including Isaacs (and Izaaks) Newton, Walton, Bashevis Singer, Asimov, Stern, Hayes, and Hanson.
 
Isaac also boasts the cute nicknames of Izzy — now shared, however, with a bevy of Isabellas — and Ike.

Isaac

Smooth and sleek one-syllable name, sometimes suggested for Sagittarius boys. 

Ives

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

James is one of the classic Anglo-Saxon names, a stalwart through the ages that is more popular—and yes, stylish—than ever today. It recently came out Number 1 in a poll of America's favorite boys' baby names, and is the most common male name, counting people of all ages, in the US.
 James, which reentered the Top 5 in 2016, is a current favorite among fashionable parents looking for a baby name that has both style and substance. Like Henry and Theodore, it manages to combine these two stellar qualities.
 
An English derivation of the Hebrew name Jacob, James is biblical (the name of two apostles in the New Testament), royal (kings of both England and Scotland), and presidential (with more U.S. Chief Executives -- six -- than any other name). The name James is also shared by countless great writers and entertainers.
 
There are fewer Jimmys, Jimbos or even Jamies these days; the most fashionable form of the name is James itself. Several stylish celebrities have chosen it in recent years for their sons, including Sarah Jessica Parker and Matthew Broderick, Liz Phair, Colin Farrell and Isaac Hanson. Brendan Fehr thought out of the box and named his daughter James, which has now become a fashionable middle names for baby girls..
James has some interesting foreign variations: Diego and Jaime (Spanish), Jacques (French), Giacomo (Italian), Hamish (Scottish), Jaako (Finnish), Seamus (Irish), Jaap (Dutch) and Jago (Cornish).
 Along with being one of the most popular first names in the US, James is also one of the <a href="https://nameberry.com/blog/top-last-names-in-the-us">most common American last names </a>.

James

This one-time trendy form of Jeremiah hovered just outside the Top 25 throughout the 1970s and 80s.
 Scout's brother Jem in To Kill a Mockingbird was christened Jeremy Atticus Finch, Jem being a very appealing nickname. Jeremy Piven and Jeremy Renner are two current bearers.

Jeremy

Latinizing Lawrence gives it a whole new lease on life. Like Leonardo, Lorenzo has been integrated into the American stockpot of names, partly via actor Lorenzo Lamas. Other associations are with Lorenzo de' Medici, the Florentine Renaissance merchant prince and art patron, Renaissance artists Ghiberti and Lotto, and the upstanding young man who married Shylock's daughter Jessica in Shakespeare's The Merchant of Venice.
 It would work well with a simple one-syllable Anglo name--in the depths of radio history, there was a soap opera character named Lorenzo Jones. And Nicole 'Snooki' Polizzi made this choice for her son.
 Renzo and Enzo are both appealing nicknames, sometimes used on their own.

Lorenzo

The related Lucas and Luke are both hugely popular boy names in the US and internationally, and now Luca has joined them on boys' popularity lists around the world.

That's an astonishing success story for a name that was virtually unknown a generation ago. Only 13 baby boys were named Luca in the US in 1980, and by 1990 it was still only 32. But by the turn of the century, Luca took off and has now surpassed his more familiar brother Luke in the US.

Boy names ending in vowel sounds may have felt too feminine to early generations who lived by more conventional gender rules. And that old school he-man America also may have rejected names like Luca for being too "foreign". But in this era of Noah and Mateo, Elijah and Ezra, Luca has finally found widespread acceptance.
Along with its popularity in the US, Luca ranks highly in a range of countries that speak English, Spanish, French, and German, among others. While Luca is technically related to Luke and Lucas and so takes their ancient Roman habitational meaning, you might also see it as a relative of Lucius or Lucian, meaning light.
 Colin Firth and his Italian wife chose Luca for one of their sons, as did Hilary Duff, Vincent d'Onofrio, Rebecca Minkoff, and Jacinda Barrett and Gabriel Macht.

Luca

Max was derived from Maximilian, a Latin name that originated from the Roman family name Maximus. The character name Max in the children's classic Where the Wild Things Are had an impact on baby namers. Max is a widely used name internationally.
 
Max was transformed from cigar-chomping grandpa to rosy-cheeked baby in the 1980s, along with card-playing partners Sam and Jake. Never quite as popular as it seemed, Max is now close to the the highest it's been on the Social Security list since 1917, after which German-sounding names went out of favor. 
 
Max has been a popular starbaby name for decades, most recently for the sons of Christina Aguilera, Cynthia Nixon and Charlie Sheen, while other celebs, such as Jennifer Lopez and Marc Anthony, have used more formal appellations--Maximilian, Maxwell, Maxfield--on the birth certificate to get to the nickname Max. Skater Scott Hamilton put his own spin on it by maximizing the spelling of his son's name to Maxx.
 
Warning: Max has long been among the <a href="https://nameberry.com/popular-names/dogs">most popular dog names</a>.

Michael was the Number 1 American boys' name for almost half a century. While Michael has moved out of the Top 10 <a href="https://nameberry.com/boys-names">baby boy names</a>, it's still widely used. 
 
How has Michael racked up this phenomenal record? Credit its use by parents of diverse ethnic and religious groups, and Michael's all-around likability, strength, and sincerity. 
 
Michael was derived from the name Mikha’el, which comes from the rhetorical question mī kā’ēl, meaning "who is like God?" in Hebrew. In the Bible, Michael is the archangel who led the other angels to victory in a war against Satan, one of only two archangels (the other is Gabriel) recognized by Jews, Christians and Muslims alike. 
 
Today, Michael may feel more like a dad name than a baby name. Substitutes you might consider include Micah, Malachi, Gabriel and Raphael.

Michael

Nicholas is derived from the Greek Nikolaos, a name that evolved from the components nikē, meaning "victory", and laos, "people." It shares origins with Nike, the name of the Greek goddess of victory. Nicholas is also a New Testament name that is well-used in literature, such as in Dickens's Nicholas Nickleby.
 
And then there's St. Nicholas who, in addition to bringing bags of toys once a year, is also the patron saint of schoolchildren, mechanics, sailors, scholars, brides, bakers, travelers, and Russia, where the name was a star of the czarist dynasty.
 
Nicholas, though it has lost some ground (it was in the Top 10 from 1993 to 2002), is still a popular classic that would make an attractive, solid choice.
 
Along with this historical depth, Nicholas, and nicknames Nick and Nicky, project an aura of masculine panache, and has long been a favorite of writers for rich boys, Romeos, thugs and detective characters.
 
Offshoots Cole and Colin have long had lives of their own. Short form Nico is hot and getting hotter.

Nicholas

Rhyley

Rufus is a rumpled, redheaded (it was the nickname for red-haired King William) ancient Roman name popular with saints and singers (e.g. Rufus Wainwright); now, Rufus is on the cutting edge of cool.
 Fellow singer James Taylor named one of his twins Rufus, and Rufus Humphrey is a Gossip Girl character. Rufus Sewell is a commanding, intense English actor.
 Rufus is mentioned in the New Testament as the name of a son of Simon the Cytherian, and there are several St. Rufuses. He's also a major figure in the George Eliot novel Felix Holt: The Radical, an honest and passionate preacher and politician.

Rufus

Sebastian is an ancient martyr's name turned literary, and Little Mermaid hero—think Sebastian the Crab—that's more popular than ever, as a classic-yet-unconventional compatriot for fellow British favorites T Theodore and Oliver.
 Sebastian is derived from the Greek Sebastianos, meaning "from Sebastia." Sebastia was a city in Asia Minor—modern day Sivas, Turkey. Sebastian is a name with a substantial history, first as the third-century martyr whose sufferings were a favorite subject of medieval artists, then as the name of memorable characters in such varied works as Shakespeare's Twelfth Night and The Tempest and Evelyn Waugh's Brideshead Revisited.
 Sebastian is high on the lists in countries as widespread as Austria, Denmark, Romania, Australia and Chile. Some more down-to-earth nicknames for the relatively elaborate Sebastian not often heard in this country are Seb, Baz and Bas. 
Several celebs have chosen the sophisticated Sebastian for their sons, including James Spader, Kim Fields, Malin Akerman and Tommy Hilfiger.

Sebastian

Old saints' and popes' name that went to France in the 1920s with the Russian Ballets Russes; in its Russian form, Sergei, it retains an artistic, almost effete air. 

Serge

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.
