An aristocratic and stately Germanic route to the popular Leo, Leopold is a royal name: Queen Victoria used it to honor a favorite uncle, King Leopold I of Belgium. These days, this royal tie may be seen as a drawback to the name, owing to the cruelty of King Leopold II's rule over the Congo, though it remains popular in Austria, Poland, and France (as Léopold).

Felix is one of those ancient but nontraditional names for boys that have come into favor over the past few decades, a favorite of parents who want a masculine name with history and heft that breaks ranks with the standard Franks and Freds. Felix is also an international darling, ranking in the Top 100 in several European and English-speaking countries.

Henry is well and truly back in style. The classic returned to the Top 10 in the US in 2021 for the first time in over a century, and as of 2024, sits at Number 6. Like James and Theodore, Henry is a strong, traditional name that also manages to feel stylish and gentle.

Llewellyn/Llywelyn is a common patriotic first name in Wales, with its distinctive Welsh double LL's; in the U.S. Llewellyn would make a daring choice, though with the chance that some might find the ellen sound slightly feminine.

Miles, which has a permanent veneer of cool thanks to jazz great Miles Davis, is a confident and polished boys' name that's an American classic. Always ranking in the US Top 1000, it's been drifting up the charts for the past half century and now ranks at its highest point ever, in the Top 50.

Arthur, once the shining head of the Knights of the Round Table, is, after decades of neglect, now being polished up and restored by stylish parents, inspired perhaps by the new generation of royals. Arthur has led the list of possible names for the young British princes, chosen as a middle name for Prince Louis, son of William and Catherine, Prince and Princess of Wales.

Magnus is a Latin name, literally meaning "greatest," that has a Scandinavian feel. It dates back to Charlemagne being called Carolus Magnus, or Charles the Great. Norwegian king Magnus I, named after Charlemagne, introduced it to his culture, and thus Magnus was the name of six early kings of Norway and four of Sweden. It is still a highly popular name in Denmark and Norway.

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.

Otto is cool again. Long a quintessential Old Man Name, Otto has been promoted to trending darling of adventurous baby namers.

Bartholomew is an apostle's name that's been out of favor for centuries but might appeal again to the parent in search of an old but rare choice. The challenge could be to avoid the Simpson-ish nickname. That character, by the way, has the full name of Bartholomew JoJo Simpson, and creator Matt Groening came up with Bart as an--uh oh--anagram for brat. Two old alternate nicknames are Barty and Tolly.

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 baby name beginning with W of all time.

Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.

Rugged but gentle, Rhys is the traditional Welsh spelling of this name, which can also be anglicized as Reese or Reece. Up until 2010, Reese was the preferred spelling in the US, perhaps because parents were concerned about mispronunciation. However, Rhys has since taken over for boys and is now used twice as often as Reese.

Simon is pure and simple (not in the nursery rhyme sense), and an appealingly genuine Old and New Testament name that's not overused. These factors make Simon a stylish yet classic choice.

Adrian is one of those names that’s easy to picture on all kinds of people. From an active and energetic five-year-old to your great grandpa, from the coolest, breeziest guy you know, to the quiet, serious one, it’s no wonder Adrian has always made the US Top 500 since the early 20th century.

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.

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.

Matthew was the third most popular boys' name in America throughout the 1980s and '90s, and is still one of the top boy names starting with M. The New Testament Matthew is the epitome of the fashionable classic—safe and sturdy, yet with a more engaging personality than John or William.

David is an enduring worldwide classic, used from ancient times to the present day.

A solid classic with plenty of history, Thomas strikes the balance between strength and gentleness. A favorite in the UK, a staple in France, and Australia, and never absent from the US Top 100, Thomas feels like a safe bet and a name that fits into any era.
