Sleek and smart, with a hint of mystique about it, Silas is a recent addition to the US Top 100. Both mythological and Biblical in origin, Silas joins the ranks of Isaiah, Atlas, Elias, and Sebastian: polished and contemporary feeling names with plenty of history.

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.

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.

Sullivan is a jaunty Celtic three-syllable name, with a real twinkle in its eye. It was immortalized in the 1930s classic film Sullivan's Travels and was chosen for one of Patrick Dempsey's twin boys. Nickname Sully is equally jaunty.

Stellan is a strong, attractive, Scandinavian possible up-and-comer, known through actor Stellan Skarsgard, and his namesake, the son of Jennifer Connelly and Paul Bettany. Its trendy 'an' ending and the similarity in sound to the popular Kellen/Kellan make it all the more accessible.

Chosen for their daughter by Bruce and Demi (inspired by the To Kill a Mockingbirdcharacter), and for her son by Tai Babilonia, an interesting choice for either sex, with overtones of a "good scout" and the upstanding qualities of a Boy/Girl Scout.

Sonny is one of the generic boy nickname names making a surprise reappearance, and it was recently used by actor Jason Lee. Another surprise: It's been on the US Top 1000 list every year since 1927, and as of 2023, it entered the Top 400 for the first time. Laidback Sonny is also popular in the UK, New Zealand and Australia.

Although Stanley Kowalski in A Streetcar Named Desire personified brute force, most Stanleys have been portrayed as meek milquetoasts. It has a totally "old-man" or "grandpa" vibe that may appeal to those who like Walter and Rupert or Daphne and Mabel.

Haunting biblical and Civil War place-name; now unisex—especially after the mega-high-profile Brangelina couple picked it for their daughter. It debuted in the Top 1000 for boys in 2015.

A name with some sterling qualities, most associated with the British currency and silver markets, though it could easily be seen as a virtue-adjacent choice, like Merit, Chosen, or Hero.

Parents who have tired of Sean are now contemplating Seamus, the Irish form of James, which has a lot more substance and verve.

Sam has long been used on its own for boys, as accepted standing by itself as it is as a short form of Samuel. Straightforward and down-to-earth, Sam is the name of the son of the co-stars of The Americans, Keri Russell and Matthew Rhys. Sam is one of the most popular names that start with S in the Western world, ranking higher in several European countries than it does in the US, where it's trended downward since the 19th century, though it's always been in the Top 1000.

Upbeat nickname-name that can't help but make you smile, along with its soundalike Sonny.
