Alonzo is dashing and debonair, with a large measure of Latin flair.
 You may be surprised to know that Alonzo has been on the Most Popular list since 1880, when such records began to be kept, at which point it was Number 110. The same is true for nickname Lon, which was 193 at the time.
 Alonso Quijano was the real name of Don Quixote--Alonso being the Spanish version of the name. In the old Judy Garland musical Meet Me in St. Louis, Alonzo/Lon was the name of both her father and brother. 
 Horror film star Lon Chaney was christened Leonidas, but Lon Chaney, Jr. was Creighton at birth. Alonzo Mourning is a former basketball star who goes by the nickname Zo--much more modern sounding than Lon or Lonnie.

Alonzo

In Spanish cultures, and spelled either Bastian or Bastien, this is a fairly common nickname name. The German fantasy children's book The Neverending Story features a young boy character called Bastian Balthlazar Bux, and it has also been seen in several screen versions. 
 Bastian has been enjoying recent popularity in Latin America: it reached Number 11 in Chile--as well as in Germany and Scandinavia, and is just beginning to be appreciated here. Jeremy Sisto used it for his son.
 Alternate spelling Bastien is also a fashionable Euro form with a possible future in America. There is a one-act comic opera by Mozart titled Bastien und Bastienne.

Bastian

Cadmus is the name of the serpent-slaying hero of Greek mythology who also founded the city of Thebes and is credited with inventing the alphabet. Its ancient feel might appeal to modern parents &mdash; especially since Cadmus Peverell is a human Harry Potter character, one of the three original owners of the Deathly Hallows.

Cadmus

Camden is a surprise hit, probably as a result of some star baby cred: it has been chosen by no less than four celebrity parents since 2012. Camden is a Jersey Boy name, along with equally popular Trenton -- these are two cases where the names are more attractive than the places that inspired them.
 Camden Town is a hip area of London, noted for its busy open-air market.

Castiel, which vaulted into the Top 1000 on the wings of the angel hero of the television show Supernatural, is the name of the Angel of the day Thursday. It may also derive some appeal from the newly-fashionable "Cas" syllable, as in Cassian and Cassius.

Castiel

Cayden is one of the many spellings of this popular name, made all the more popular when they're counted together. According to our annual Playground Analysis, Cayden and brothers rank a cumulative Number 14 among boys' names, given last year to more than 11,000 baby boys in the US.

Corbin, the name of the castle where the Holy Grail was said to be hidden, came to the fore in the 1980s via actor Corbin Bernsen when he was the high profile star of LA Law, but its use is only now escalating as part of the mania for two-syllable names starting with c or k, as well as from the more youthful image of Corbin Bleu, the attractive actor-model-dancer-singer who was one of the stars of the Disney hit High School Musical. 
 Bruce Willis's character name in The Fifth Element was spelled Korben Dallas.

Corbin

Both offbeat and upbeat, this evocative traditional Irish name that runs through Celtic mythology is known here via award-winning novelist Cormac McCarthy (born Charles). The author's adopted name is related to Cormac Mac Airt, one of the great legendary high kings of Ireland.
 In two of the Harry Potter movies, Cormac McLaggen is a Gryffindor student.
 And for all you popularity-phobes, Cormac has never yet made it onto the American Top 1000 list.

Cormac

Dimitri is a Slavic variation of the Russian Dmitriy, a name that comes from the Greek Demetrius. Demetrius was derived from Demeter, the name of the Greek goddess of fertility and farming. Among the possible spelling variations are Dmitri, Dmitrii, Dmitriy, and Dmitry.
 
Dimitri is a worldly, artistic, and attractive name. It has been on and off the bottom of the US Top 1000 list in recent years. Dmitri is another possibility that may prove more challenging for some English speakers to pronounce, although it was the spelling Mila Kunis and Ashton Kutcher chose for their son.

Dimitri

Dominic comes from the Latin name Dominicus and is common in the Roman-Catholic community. In the past it has been given to boys born on Sunday—the word "Sunday" in languages including Spanish and French shares Dominic’s roots. In use in the English-speaking world since medieval times, its most famous bearer was St. Dominic, founder of the Dominican order of monks in the thirteenth century.
 
Dominic is a name with two very different images: In Britain, it's an upper-crust staple, while in the U.S., it still retains a bit of downmarket Jersey Shore feel. We say it's a strong, venerable name deserving of respect on both sides of the pond, which it is finally getting. Dominic has been in the Top 100 since 2002.
 Dominic West was one of the charismatic stars of The Wire and The Affair; Mario Lopez named his son Dominic, nicknamed Nico.

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>.

Emmett, honest and sincere, laid-back and creative, is on the rise as a male cognate of the megapopular Emma and Emily, not to mention being a character in the popular Twilight series.
 Emmett originated in England as a masculine diminutive of the German Emma; the Hebrew characters pronounced eh-MEHT mean truth, so that might be considered another definition. Emmet is another, less popular spelling.
The death of young Emmett Till helped spark the civil rights movement.

Emmett

Nearly unknown outside the British Isles, this old Scottish variation has a sleek surname feel that can make an excellent update of the flagging Christopher.

Lachlan is as Scottish as haggis and tartan plaid kilts—a favorite used throughout England, Scotland, Australia, and New Zealand—and just beginning to be noticed in the US: it reached the Top 1000 for the first time in 2013. An ancient name, Lachlan was originally used to describe the Viking invaders of Scotland, those from the land of the lochs.
 Americans and Australians tend to pronounce the first syllable of the name like Lock, but the genuine Scottish pronunciation sounds more like Lack.
 In Ireland, the name was Anglicized as Laughlin; in Scotland the pet forms are Lach, Lachie, or Lockie.
 Lachlan has been a top name in Australia for at least a decade. It has been in the headlines recently via the eldest son of media mogul Rupert Murdoch.
 Somewhat surprisingly, Lachlan has US presidential cred, as the son of tenth president John Tyler, whose other children included Lyon, Letitia, Tazewell, and Pearl.

Remy is one of the hottest names today for both boys and girls, sometimes spelled Remi. . It entered the popularity list in 2009 and has quickly become one of the fastest-rising names on the list.
 Remy came into the spotlight via the 2007 Disney film Ratatouille, starring an ambitious chef named Remy—who happened to be a rat. The name has also been borne by a variety of human characters in The Da Vinci Code, House, New Girl, and The Fairly Oddparents.
 The name of a fifth century saint and one of a new generation of <a href="https://nameberry.com/baby-names/162/french-names">French names</a> being discovered in the US, Remy is one of those ancient names that sounds particularly modern and attractive.

There's Rhys and there's Reese (now more popular for girls) and there's Reece, and we particularly like the traditional Welsh spelling, which entered the list in 2004, possibly influenced by Jonathan Rhys Meyers, of The Tudors, and Welsh-born actor Rhys Ifans.
 Always widespread in Wales, where it has deep historic roots, Rhys is also a high-ranking name in England, Ireland and Scotland.
 Former New Kid on the Block Joey McIntyre named his son Rhys Edward in 2009.

Parents who have tired of Sean are now contemplating Seamus, the Irish form of James, which has a lot more substance and verve.
 One of the name's most famous bearers is the 1995 Nobel Prize-winning Irish poet Seamus Heaney. Seamus is also a Harry Potter name—Seamus Finnigan is a half-blood wizard friend of Harry's.
 At a time when the police force was predominantly Irish, "shamus" became a slang term for a detective.

Seamus

This gentle Scandinavian name, soft and sensitive, is being discovered in a major way by parents in the US. It's most closely identified with the nineteenth century philosopher Soren Kierkegaard, but there have been modern fictional Sorens as well, in The Matrix Reloaded and the book series Guardians of Ga'Hoole, Charlie and Lola, and Underworld.

 In Scandinavia this name would be spelled as Sören or Søren, leading to it being pronounced "Sur-en". But with a plain old English "O", "Sorr-en" would actually be the correct (and more English-speaker friendly) pronunciation.

Soren

One of the few ancient Roman names that doesn't end in us, the rarely heard Tarquin has a decidedly creative, even dramatic flair, which could appeal to the parent looking for a strikingly original name. Sir Laurence Olivier used it for his oldest child, who was named Simon Tarquin but called by his middle name.
 As Tarquinius, it was borne by two early kings of Rome.
 Tarquin has some literary cred as well, appearing in Shakespeare's poem The Rape of Lucrece (referring to a dark stain on the name), as Tarquin Blackwood in Anne Rice's The Vampire Chronicles series and as Tarquin Cleath-Stuart in the Shopaholic series by Sophie Kinsella.

Tarquin

Tristan -- known through medieval legend and Wagnerian opera -- has a slightly wistful, touching air. This, combined with the name's popular "an" ending, makes Tristan very appealing to parents seeking a more original alternative to Christian.
 One influence was the character Tristan Ludlow played by Brad Pitt in the 1994 movie Legends of the Fall, based on a Jim Harrison novel.
 Tristan is a dragon-slaying hero of Celtic legend, whose story was incorporated into Malory's Le Morte d'Arthur, in which Tristan is one of the Knights of the Round Table, consumed by his doomed love affair with Queen Isolde. Wagner set the story to music in his opera Tristan und Isolde.
 Tristan and its alternate form Tristram have been found in later lit as well. Tristram Shandy is a famous early comic novel by Laurence Sterne (in which the hero's father calls Tristram the worst name in the universe); Tristan is a major character in James Herriott's All Creatures Great and Small, and there is an eponymous novella by Thomas Mann.
 Particularly popular in Canada, Tristan was chosen for their sons by Travis Tritt, Wayne Gretzky, Natasha Henstridge and, most recently, by Elsa Pataky and Chris Hemsworth. Basketball player Tristan Thompson hails from Canada.
 Other variants of Tristan include Tristen, Tristin, Triston and Tristian.
