Thanks to two cultural influences, January has joined March, April, June and August as a plausible month name.

The line should end with Junior Soprano. While most would expect this to be a nickname rather than an actual given name, Junior has always ranked in the US Top 1000, hitting its peak in 1925 at Number 116.

Jackie Kennedy gave this name a lot of style, but it doesn't seem destined for a comeback the way brother name Jack has. Jackie and Jacqueline both peaked in 1961.

A variation of Jameson. Both names have climbed in popularity in recent years, though Jameson remains the preferred spelling.

The biblical Judith, the fourth most popular name in 1940, may be getting ready for a comeback in its full, elegant, if somewhat solemn form. Many of those earlier Judiths were called Judy—some after Judy (born Frances) Garland—preferring it over their more formal proper name. Today, Judith, like Deborah, may have shaken off just enough to appeal to parents looking for a traditional, yet under-the-radar biblical name. And Jude would be a likelier nickname these days than the Judge Judy connection.

See JASMINE.

Jessie has never been used as much as Jennie/Jenny, partly because it's a boys’ name as well (spelled Jesse), but it does have a friendly and unpretentious pioneer feel. In Scotland, it's found as an Anglicized form of Teasagh, itself a form of Jean, and is used as a full name. And in the rest of the world, Jessie may be short for Jessica or used on its own.

A Jada alternative that has lost ground this decade after peaking around 2010.

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.

Long used in Spanish-speaking countries, this strong but feminine name was jump-started here by the rise of actress Jada Pinkett Smith. The Italian Giada is a popular variation. In the Bible, the name Jada was borne by a man and has a different root and meaning: It's Hebrew and means "he knows".

For a minute or two this sounded more modern than Janet, now equally outmoded.

Every other little kid's name in 1957 but few Jameses are called Jimmy today; they're more often James or Jamie.

Jarred is a masculine name that emerged as a variant spelling of Jared, which has Hebrew origins meaning 'descent' or 'he who descended.' This alternative spelling became particularly popular in the United States during the 1970s and 1980s. The name has biblical roots, as Jared appears in the Book of Genesis as a patriarch before the flood. Jarred offers a slightly more contemporary feel than the traditional spelling, with the double 'r' adding a distinctive visual element. The name conveys strength and masculinity while remaining approachable. Though its popularity has declined since its peak, Jarred continues to be chosen by parents who appreciate its biblical connections combined with its modern spelling variation.

Johanna is the version of this name used in Holland, Germany, and Scandinavia. The extra h makes Johanna a slightly more dignified version of Joanna.

Wildly popular in the 1960s and '70s, Julie is no longer anywhere near as stylish as the name's longer forms. Try Juliet, Juliana, or even the more grownup Julia.

This nickname for popular and traditional Joseph has a long history of being used as a given name all on its own. Nonetheless, everyone will always assume that Joey is short for the longer form. It might be nice for a potential son to have the option of a more professional and classic name to fall back on.

Once rare, this streamlined form of Jessica has been boosted by two very different television figures: the Jemima Kirke character on HBO series Girls, and reality television daughter Jessa Duggar.

Justice is a fashionable word name, used for both girls and boys. Justice has the distinction of being a virtue name without the religious implications of Faith or Grace. It still feels more male than female, perhaps partly due to the classic Roman name Justus, but Justice has become a more common pick for girls in recent years.

Jagger is a swaggering Rolling Stone of a name that's been picked up by a number of fellow celebs, including Lindsay Davenport and Brett Scallions--while Soleil Moon Frye pulled a gender switch when she bestowed it on her daughter. It's edgy with a touch of danger.

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.
