AD - BOYS NAMES

This steely surname has a macho image that might feel more appropriate for a romance novel than a baby. But on the upside, it's also sleek and modern, familiar yet unusual, given to only around 100 boys per year in the US.

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.

Stephen, also spelled Steven, is a strong and likable classic, with the he's-a-great-guy short form Steve. Though not as well-used or fashionable as it was in its heyday -- it was a Top 25 name from 1946 to 1957 -- it's still a widely used name. It remains an even more popular in Ireland.

A name with some sterling qualities, most associated with the British currency and silver markets. Sterling has several recent TV associations, with characters Roger Sterling (on Mad Men) and Sterling Archer (on Archer), and actor Sterling K. Brown (on This is Us).

Best known as a popular brand of Western hats, this surname gives off rugged, cowboy vibes and a sense of confident coolness. A name on the rise, Stetson entered the US Top 200 in 2023 when it was given to nearly 2000 boys.

Despite its somewhat menacing meaning, this name has been widely used in recent years, probably due to the appeal of its trendy on ending.

One of the hot two-syllable T names of the nineties (along with Tyler, Trevor, and Taylor), and well represented on soap operas; Tanner is still widely used, but its popularity is declining.

A strong single-syllable surname with a joyful meaning, Tate is finding a place on more and more birth certificates.

Few people would have considered the surname of this famous Victorian poet as a first name until Russell Crowe chose it for his son in 2006. But, as a rhythmic three-syllable patronymic, Tennyson has a lot going for it, not least of all the appealing nickname Tenny; it would make a novel choice for the son of a Dennis.

Thad is a tad too slight to stand alone as a name, though as a short form of the imposing Thaddeus it's as serviceable as Ted or Ed.

Thaddeus, a distinguished, long-neglected name, has several areas of appeal: a solid New Testament legacy, a nice antique feel, and the choice of several more modern nicknames and international variations.

Thatcher is an open and friendly freckle-faced surname, fresher sounding than Tyler or Taylor, that dates back to the days of thatched-roof cottages. It is catching on with modern parents—it reached the US Top 1000 for the first time in 2013.

Thayer is an affable, less-common alternative to Taylor, with a much more indirect connection to its occupational source. Actor Thayer David (born David Thayer: Thayer was his father's first name) was known for his roles in Rocky and Dark Shadows.

See the popularity graph below for the name Theo? It's been heading straight uphill since 2010, when it hopped back onto the Top 1000 after a 60+ year absence.

As unlikely as it may seem, Theodore is a hot new hit name, vaulting into the Top 10 in 2021 for the first time ever and rising three more points last year to rank at Number 7.

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.

Thor, the powerful name of the Norse god of thunder, strength and rain, would make a bold statement. Long a comic book staple, Thor has now invaded the big screen, and could land on birth certificates as well.

A dashing French surname name most famously borne by Henry David Thoreau, an American naturalist, writer and philosopher who influenced such notable figures as Leo Tolstoy, Mahatma Gandhi, and Martin Luther King Jr. The most common modern American pronunciation is "thor-OH", with emphasis on the final syllable, although Thoreau himself pronounced it "THOR-oh".

As the mythological Thor morphs into a modern baby name, the variations Thoren and Thorin feel like real possibilities, not just in Scandinavia but around the Western world.
