Atticus, with its trendy Roman feel combined with the upstanding, noble image of Atticus Finch in To Kill a Mockingbird, is a real winner among boy names. Atticus entered the US Top 1000 in 2004 and is a firm Nameberry favorite.

Classic and elegant but with boyish charm, Theodore has become hit name in recent years, vaulting into the US Top 10 in 2021 for the first time ever and into the Top 5 in 2024. A favorite in English speaking countries, it also ranks highly across the UK and Ireland, and in Canada, New Zealand, and Australia.

Nico is one of the great nickname names, full of charm, energy and effortless cool -- a neo Nick.

Gentle but grandiose and beloved by British novelists including Evelyn Waugh and P. G. Wodehouse, Ambrose was a fast rising name in 2022. Entering the UK Top 1000 for the first time and proving popular among Nameberry users, its elegance, softness, and vintage style means it fits in with popular Theodore, Sebastian, and Jeremiah.

This ancient name, also spelled Caspar, is finally shedding its ghostly image and moving into the 21st century. Popular in the Netherlands and Scandinavia, where it's sometimes shortened to Cas, Casper could ride the style coattails of cousin Jasper.

Solid and intellectual, with just a touch of ruggedness thanks to that rad ending, Conrad has appeared consistently in on the US popularity charts since the 19th century. Over the years, it has been leant a literary air by the writer Joseph Conrad, a pop of rock energy by the Elvis-like character in the movie Bye, Bye, Birdie, and more recently, a serious, kind-hearted, and handsome feel by The Summer I Turned Pretty.

Daniel is one of only a handful of male names that sounds both classic and modern, strong yet approachable, and popular but not cliched. It also has a solid Old Testament pedigree. The only real downside: There are about 10,000 Daniels named each year, making it a less than distinctive choice.

Lysander is a distinctive Greek name that could be thought of as a more creative cousin of Alexander. In ancient history, Lysander was the name of an esteemed Spartan naval commander and his literary cred comes from one of the two star-struck young men in Shakespeare's A Midsummer Night's Dream, as well as one of the twin sons (the other being Lorcan) of Luna Lovegood, whom we learn about in the Harry Potter epilogue.

Succinct, stylish, and catchy, Ivo has the energetic impact of other names ending in -o. It is a multicultural choice with two distinct origins, and, as such, is familiar across a variety of countries, ranging from the Netherlands to Brazil, from Portugal to Czechia.

Caius is classical and serious but also has a simple, joyful quality. There was a third century pope named Caius, as well as an early Christian writer, several Shakespearean characters, and a Twilight vampire. We would pronounce the name to rhyme with eye-us though at Cambridge University in England, where it's the name of a college, it's pronounced keys.

Michael was the Number 1 American boys' name for almost half a century. While Michael has moved out of the Top 10 baby boy names, it's still widely used.

Lewis is the best spelling to choose if you want this pronounced with the S. It was a Top 100 name in the US from 1880 to 1930, reaching Number 30 in 1880 and while it has declined in use, it has remained in the Top 1000 since stats began.

Sophisticated Gallic version of Lucian, Lucien may appeal to parents attracted to this meaning over that of Lucas and Luke, which have a different root, and also looking for a more unusual choice.

Isabel, Theodore, and Isadora are back: could it now be time for a more widespread revival of Isidore? Yet to see any big moves up the charts, Isidore was given to more than 30 boys in a recent year: twice the number it was given to a decade ago.

With Matthew sounding somewhat exhausted, and ancient endings sounding new again, this New Testament apostolic name makes an appealing and recommended choice. Both Mathias and Matias are well used in the Hispanic community, and throughout Europe. Will Ferrell and his Swedish wife chose Matias for their second son.

This attractively energetic Italian version of the classic Matthew is primed to move further and further into mainstream American nomenclature. Mateo is technically the Spanish version, but many parents in the US use the two spellings interchangeably.

Calix is once-obscure name that is starting to see some use in the US, where 62 baby boys were named Calix in 2024. An indirect influence is the actress Calista Flockhart, who introduced Americans to the female version of this attractive Greek name to prominence.

Madonna did much to polish up the image of this old-neighborhood Italian choice when she picked it for her son with British director Guy Ritchie, and several years later it was also used by Rose Byrne and Bobby Canavale for their son. It now feels much more mainstream than many celebrity baby names, sharing the quirky appeal of some other so-far-out-they're-in baby names as Bruno and Hugo.

Rugged and tough, Anderson shot up quite a bit on the pop list in the 2000's, no doubt in large part due to the prominence of white-haired cable newsman Anderson Coopers, more recently, it has featured in the US Top 400, given to 943 boys in the latest count.

Adlai is an Old Testament name long associated with 1950's liberal presidential candidate Stevenson, who was named after his grandfather, who was Grover Cleveland's vice president in the nineteenth century. Now it's an unusual Biblical choice ripe for rediscovery.
