While Jadon is the authentic biblical name, Jaden is by far the more popular spelling, first noticed when Will and Jada Pinkett Smith used it for their now grown (and famous) son. It has since swept the country for both sexes, with a wide variety of spellings and rhyming cousins.

With Old European vibes, Johan is a variant of the classic John, similar to the Latin, Hebrew, and Germanic forms, Iohannes, Yohanan, and Johannes.

This name of the ten-year-old boy in the much loved and acclaimed modern classic To Kill a Mockingbird could find favor along with that of the character's sister, Scout.

A cutesy short form of Jordan that's never been overly popular. Pro Bowl wide receiver Jordy Nelson is one famous bearer.

Jacoby, a surname spin on Jacob shot up the charts in the middle of the 2000's, thanks largely to the popularity of Jacoby Ellsbury, the first Native American of Navajo descent in the Major Leagues, but has been dropping steadily since it peaked at Number 423 in 2008. As of 2022, it dropped out of the US Top 1000 and is given to around 170 boys each year.

Jennings is a common English surname that originated as a patronymic for the child of someone named Jen, a short form of John.

The meaning of this ancient Roman god's name relates to transitions, hence its connection to the name of the first month of the new year, a time of fresh beginnings. Janus is usually depicted as a two-faced god facing in opposite directions, since he looks both to the future and the past. It's no surprise then, that Janus is one of the premiere January baby names. The Slavic form Janusz is more commonly used than the English, represented by the Polish cinematographer Janusz Kaminski, who has shot all of Steven Spielberg's films from Schindler's List to Lincoln.

Coolly attractive African name, with distinguished representatives in sports and literature. Jabari has been on the rise recently, returning to the US Top 1000 in 2023.

Streamlined version of the classic boys' names, sometimes a short form of Jonathan, which is in fact an entirely different name from John attached to a different Biblical personage. Jon feels more modern than the traditional John, but some may find it an overly slight variation on an already slim name. Jon Snow is a popular character on HBO's Game of Thrones.

More popular than the Jalen spelling. Like other names with many variants, when you count up all the alternatives, the name is much more popular than it first appears.

The New Jersey cities of Camden and Trenton are in, but the name of the state has not caught on to anywhere near the same extent, possibly due to its association with knitted pullovers and reality TV. Nevertheless, Jersey peaked as a masculine name in 2022, when it was given to around 60 boys.

The name of the third U.S. President sounds, like Harrison and Jackson, more modern and stylish now than its root name. Used as a first name long before our surname-crazed era, Jefferson was most famously used as a first name by the President of the Confederacy, Jefferson Davis, which may justifiably make you not want to use it. Jefferson is the middle name of another Prez, William Clinton.

A rarely-used name even in its native Cornwall, Jory nevertheless feels very wearable, thanks to its similarity to familiar picks like Rory, Corey and Joey. Jory Cassel is a minor character in the first season of Game of Thrones.

Both Jeb and Jed are very attractive Old Testament short forms with long and bright futures. Jeb's main current association is with the Bush brother and former governor of Florida, but the name was a mainstay on early TV westerns, and then went upscale as the nickname (his birth name being Josiah) of the President on "The West Wing."

We've had Jackson, Jaxcon and Jaxon, and now we have Jaxton.
