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.

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.

One of the coolest of names, thanks to legendary jazz pianist Thelonious Sphere Monk, who inherited this Latin-sounding German name from his father. It has been used very sparingly since the 1960's, with just a sprinkling of baby boys receiving the name each year, though it's one of the unique baby names we predict will get much less unique as more parents embrace its quirky charms.

Tristan -- known through medieval legend and Wagnerian opera -- has a slightly wistful, touching air. This, combined with the name's popular "an" ending, makes Tristan very appealing to parents seeking a more original alternative to Christian.

Tucker has more spunk than most last-name-first-names, and also a positive, comforting ("Tuck me in, Mommy") feel.

A surprising number of parents choose to put the nickname Tommy on their son's birth certificate rather than the more traditional Thomas. Perhaps even more surprising is thE fact that Tommy has never been off the United States popularity charts. More recently, however, the name has been trending downward.

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

Teddy is in some ways one of those midcentury boys' nicknames -- like Jimmy or Bobby or Billy -- yet because it was never that popular, it feels timeless too. The preferred short form of Theodore these days may be Theo and of Edward may be....Edward, but Teddy can work adorably for either and grows up to Ted. And of course, let's not forget the inevitable teddy bear.

Tatum is one of the rare examples of a name that was exclusively female, as in Tatum O'Neal, but now is used for boys too, entering the male Top 1000 in 2010. Khloe Kardashian made headlines when she revealed her son is named Tatum Robert, breaking from the family theme of using unique word names for their children.

The presidential Tyler rocketed up popularity charts in the late 1980s and early 1990s (it ranked Number 9 for that entire decade), along with cousin Taylor, becoming almost pandemic across the land-- and to make matters more confusing, both (especially Taylor) have been used for girls as well.

Taylor was much more popular throughout the 1990s for both genders than it is today. Close to the Top 50 boys' names in the mid-1990s, Taylor recently fell out of the Top 500 for boys and out of the Top 100 for girls, and is predicted to continue on a downward trajectory for both genders. Similar but more stylish baby names today include Sawyer, Sayer and Thayer.

Truett is one of the trendier names in the Tru- family (True, Truman etc), which was used for 92 boys in the US last year. Truett is deeply associated with the Baptist church in the Southern USA due to former leader George Truett. Truitt is another spelling, less commonly used. Some sources say that Truett, as a surname or a first name, is a habitational name -- a name given to people who lived in a certain place -- in this case, Trewhitt in England's Northumbria. The place name is drawn from the Old Norse tyri meaning "dry resinous wood" and the Old English whit, which means river bend. It's an appealing name, though say it too quickly and it can sound disturbingly like truant.

Sweet and spirited, kindly and handsome, posh and approachable, Toby is a versatile nickname, popular in the UK as a stand-alone choice, but familiar in the Netherlands and New Zealand too. In the US, it had its heyday in the 70s but has since been outranked by long form Tobias.

America has fallen in love with Hayes and Brooks and Banks and Rhodes, and now, parents are turning to Townes. With its fashionable S ending and image that can read as preppy or country or cowboy, depending on the context, Townes feels destined for mainstream success.

Has a laid-back rural feel some would associate with country singer Travis Tritt; Kyra Sedgwick and Kevin Bacon chose it for their son. Travis Scott, born Jacques Webster Jr., a popular rap artist, is another famous Travis.

Tony, as in classy. Or To-nyyy, as yelled out a tenement window.

A 1970s beach boy surfing buddy of Scott, Brad, and Chad, Todd is given to relatively few babies these days.

Some high-profile soccer stars, such as Thiago Silva, have contributed to its success. The correct Portuguese pronunciation is chee-AH-go. Thiago is ranked Number 2 for boys in Puerto Rico.

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.

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.
