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

Justine is a French name that's never reached the popularity we think it deserves. Like its far-more-common brother Justin, Justine is sleek, and sophisticated, but still user-friendly.

The ancient boys' name Jasper is popular internationally in a range of forms, including Casper and Gaspard, and now Jasper is beginning to be used for girls in the US.

A Top 100 name from the 1930s all the way through the 1950s, it's now firmly in Mom -- or Grandma -- land and supplanted for babies by Joanna.....or even great-grandmother Josephine. In its heyday, it had a host of variations, including JoAnn and Jo-Anne.

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.

This once obscure name was propelled to fame by Britney Spears, and by Will and Jada Pinkett Smith in the 2000's. It skyrocketed into the US Top 10 for boys, but it also saw significant use for girls.

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.

Judy was the nickname of choice for almost all the Judiths born in the 1940s and 50s; today's little Judiths are much more likely to be called Judith -- or, possibly, Jude.

Not quite as unusual as it might seem, it first entered the popularity list in 1995, as a possible alternative to the very popular Kayla. In the Bible, an alternate spelling is Jaala.

One of the new word names, appealing to parents attracted to the idea of a spiritual -- or even an actual -- voyage. The Journee spelling is also being used. Unisex alert: Jenna Jameson used Journey for one of her twin boys, as did the Black Eyed Peas rock musician known as Taboo.

The name Jo still evokes the spunky image of the character in Louisa May Alcott's Little Women. Its literary status makes Jo one of the OG boyish nicknames for girls, ala Frankie, Billie, and Stevie. If you like that form, you can lengthen it to Joey.

One of the group of French 'ette'-ending names that emigrated to this country in the last century, though never as popular as some others, such as Claudette and Paulette--it did have a little six-year flurry here between 1967 and 1973. Josette may be feminine and flirty, but, given the choice, most parents today would prefer Josephine.

Relic of a past period of French favorites, out to pasture with Claudette and Paulette.

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.

Joss is more fashionable than Jocelyn or Josslyn. This is a short form that could be used independently, a la the singer Joss Stone. One of a troupe of adorable boyish nicknames newly fashionable for girls a la Lou and Charlie.

While Jay has been long used as a stand-alone boy name, it has more recently been used as one for girls. Otherwise, it has largely been seen as a pet form of any J name, or as a singular middle name.

A feminization used more before Jordan joined the girls' camp.

Josephina is a feminine form of Joseph, ultimately derived from the Hebrew name Yosef, meaning 'God will add' or 'God will increase.' This elegant variation combines the biblical gravitas of Joseph with a distinctly feminine ending. Popular in Spanish-speaking countries as Josefina, the Josephina spelling is less common but maintains the same melodic quality. The name offers versatile nickname options including Jo, Josie, Fina, or Phina. While not ranking among top names in the US or UK, Josephina appeals to parents seeking a traditional yet distinctive name with religious roots and cross-cultural appeal.

Musical choice that may be a short form of Jasmine or Jazlyn, or might stand on its own like this or as Jaz, the spelling used by tennis duo Steffi Graf and Andre Agassi.

With Journey becoming increasingly popular, it's no surprise that this alternative spelling is not far behind. However, you may be surprised to learn that in recent years, the Journee spelling has actually passed the original spelling in popularity — Journee is currently in the Top 200. This word name may be appealing to parents attracted to the idea of a spiritual -- or even an actual -- voyage.
