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.

A versatile classic, Lucy is both sweet and solid, a saint's name, and the heroine of several great novels. First fashionable in England and Wales, Lucy is now a popular choice in the US, The Netherlands, and New Zealand.

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.

Simple, classic, strong, and versatile, Jane has shrugged off her plain associations to become a short, punchy name with plenty of literary significance. Calling to mind Jane Austen and Jane Eyre, this charming choice is in the Top 300 in the US and The Netherlands, but a currently underused option elsewhere.

Leo is a strong-yet-friendly name that was common among the Romans, used for fourteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

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.

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.

Julia was an ancient Roman imperial name given to females in the house of a Julius, as in Caesar. Its origin is shrouded in history, but possible roots include Latin iuvenis, meaning "youthful"; Greek ioulos, meaning "downy-bearded"; or Jovis, a form of Jupiter, which means "sky father".

Lucian is a sleeker, more sophisticated version of Lucius that is climbing in tandem with other Lu-starting names.

Clementine is a Nameberry favorite that broke back into the US Top 1000 in 2014 after more than half a century off the list.

Effortlessly stylish, with plenty of sweetness and strength, Valentina feels like a fresh alternative to Valerie, Victoria, or Vanessa.

Peter is derived from the Greek Petros, meaning "rock" or "stone." One of the most important figures in the Christian hagiography is Saint Peter, keeper of the Gates of Heaven. Born Simon bar Jonah, he was given the nickname Peter by Jesus, to signify that he would be the rock on which Christ would build Christianity. Centuries later, there was Peter the Great, the czar who developed Russia as a major European power.

Zachary, a Top 20 name throughout the 90s, is now sliding down the rankings though it remains in the Top 200. With its ancient roots and modern feel, it's easy to understand why Zachary has been such a longtime winner.

Felicity is as accessible a virtue name as Hope and Faith, but much more feminine -- and dare we say, happier. The hit TV show did a lot to soften and modernize the once buttoned-up image of Felicity, and it got further notice as the red-haired Colonial doll, Felicity Merriman, in the American Girl series. A current bearer is actress Felicity Huffman.

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.

Lucia is a lush, rich Latinate equivalent of Lucy, popular in Spain and throughout Latin America and also a cross-cultural favorite. You might be surprised to know that Lucia has ALWAYS ranked among the Top 1000 girl names in the US, though she's really taken off only since the turn of this century.

Victor is one of the earliest Christian names, borne (as Vittorio) by several saints and popes, symbolizing Christ's victory over death. It has been quietly in the Top 200 since 1880, but just recently has taken on a cool edge by fashionable parents in London and seems ripe for a similar reevaluation here too.

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.

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.

Soft, light, and international, Pia is familiar across Europe, South America, and Asia. Usually considered a feminine form of the Latin Pius — lending it a surprisingly serious and spiritual air — it may also be used as a short form of elegant Olympia or as a derivative of the Sanskrit priya meaning "beloved".
