Joel is one of those boys’ names that's never been super-popular yet has never been UNpopular either -- it's been in the Top 400 in the US since we started keeping statistics in 1880. So it's inevitable that its female form Joelle would gain visibility too, and indeed Joelle was used most widely during Joel's reign in the Top 100, from the late 1960s through the early 1990s.

A cute nickname, but June is a much better bet for the birth certificate.

Will this old-fashioned nickname make a comeback, now that Jane has shed her "plain" image? Janie is cute and approachable, and would stand as well on the birth certificate as Josie and Jessie do now.

Jessamine, a charming name occasionally heard in England, is just beginning to be appreciated in the U.S. as a possible successor to all the Jess names of the past. It's also spelled Jessamyn, as in Quaker novelist Jessamyn West, author of Friendly Persuasion--who started life with Jessamyn as her middle name.

A sweet name with many cross-cultural ties: it's an equivalent of Jane in languages including Czech, Slovak, Dutch, German, Slovene, Catalan, Estonian, and Latvian.

Has lost all trace of its French accent.

Jerry is one of those short forms that, like Mike and Debbie, rose to popularity on the coattails of their formal versions. The equivalents today are nickname names like Ellie and Theo.

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.

Jayce, which probably started out as an abbreviation of names like Jason, with the 'y' borrowed from Jayden, now has a life of its own, making a strong showing on the popularity lists. It is currently in the US Top 200 and features in the charts in the UK and The Netherlands.

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.

Jaxon has been mostly climbing in popularity since it entered the Top 1000 in 1997, proving that many parents have decided to rev up the cool factor of Jackson by giving it this streamlined spelling. (Though we still prefer the original.)

Jolie is as pretty as its literal meaning; nowadays it is also seen as a girls’ name, via Angelina for whom Jolie was originally her middle name.

Judd is a strong but sensitive short form that can easily stand on its own, the second 'd' giving it a lot more substance, and it would also be a good middle name choice. Two recent actors have given it credence--Judd Nelson and Judd Hirsch, and now it's most noticeably represented by comedy director Judd Apatow.

The surname name Jenson is in the British Top 100 thanks to champion race car driver Jenson Button. Jenson might be an honorific for an ancestral John, the English form of Jens or Johannes, or even Jen.

Jago is a dashing alternative to overused favorite Jacob.

Jacinta, the Spanish word for hyacinth, is a lot softer and sweeter than the English version. The correct Spanish pronunciation is ha-SEEN-ta, though many English speakers would say ja-SIN-ta. Although the name is slightly different, Jacinta is largely associated at present with Australian-born actress Jacinda Barrett.

Journey is one of the hot new spiritual names. Although Journey was given in 2015 to over 1100 baby girls and fewer than 100 baby boys, it's more visible on the celebrity baby scene as a boys' name: Megan Fox and Brian Austin Green just chose the name for their third son, who also has the unisex middle name River.

Juan, the Spanish version of John, is ubiquitous in the Spanish-speaking world, and is familiar internationally via such references as Don Juan and San Juan.

Juna, a variation of the newly stylish month name June, goddess name Juno, or literary Djuna, is among the fresher-feeling girl names starting with J. While Juna has never been given to more than 50 baby girls per year in the US, it's a popular choice in Germany, Switzerland and the Netherlands.

Pronounced just like Jean in the English-speaking world, but as the more unusual zhahn in France, this has sailed away with the first wave of French favorites: Denise, Michelle, et soeurs.
