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.

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.

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.

Sawyer is a surname with a more relaxed and friendly feel than many others, and is one of the hottest occupational names right now, with the Nameberry seal of approval. Sawyer is becoming one of the top unisex names. Both Sara Gilbert and Diane Farr used Sawyer for their daughters, while it was given a boost as a boys' name by the character Sawyer on Lost, an alias for the character really named James Ford.

Shepherd is an occupational surname with a pleasant, pastoral feel, an outdoorsy vibe, a gentle sound and a cool, contemporary energy. The name has been rising steadily in the US since the mid-2000s, but it didn't break in to the Top 1000 until 2016. Since then, it has become a fresh but familiar choice, ranking in the Top 350 in a recent year.

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.

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.

Shane ambled into the picture via the 1953 movie, adding a cowboy twist to its Irish essence. A variation of Sean with a hint of Shay and Zane, it is a popular choice in Ireland.

Spencer is a name that has everything: it's both distinguished sounding and accessible, dignified but Spencer Tracy-like friendly. Picked by several celebrities (a couple of times even for a girl), adding up to an enthusiastically recommended choice.

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.

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.

A contraction name, Sidney comes from Saint Denis and is related to Dioynsius, the Greek god of fertility and wine, although another theory is that it derived from an Anglo-Saxon place name, meaning 'at the wide island.'

A modern, multifaceted name, Sage is short, sweet, and strong. A unisex possibility, it is also a virtuous word name associated with wisdom, and a nature name linked to a fragrant herb.

The long-neglected name of Adam and Eve's third son after Cain and Abel, Seth is appreciated for its gentle, understated presence -- and strong middle-name potential. It reached a high of Number 63 in the year 2000.

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. It has been a rising star in the US in recent years, appearing in the Top 400 in the latest count, when it was given to 880 boys.

For every Tio Salvador in a Latino family, there's a Zio Salvatore in an Italian one. Having always ranked in the US Top 1000, it is in danger of falling off the charts very soon.

A jaunty offshoot of Sullivan, Sully will be associated by kids with the beloved character in the Pixar animated film Monsters, Inc. Some notable real-life namesakes are French poet and essayist Sully Prudhomme, the heroic pilot "Sully" Sullenberger, and Sully Erna, lead vocalist of Godsmack.

This name of three early popes has been associated in recent years with a cocky cartoon cat ("Thufferin' thuccatash!") and the Italian Stallion hero of the Rocky and Rambo movies (who was born Michael) — and yet we think it just might be ready to move further back into the mainstream.

With the prevailing popularity of Samuel, some parents are considering this more (literally) powerful biblical name, which shares the desirable nickname of Sam.
