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.

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.

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

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.

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.

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.

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.

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.

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.

Jara is a name with roots in several different cultures and languages, with different meanings and associations. She's the Hindu goddess of the household, happiness, and prosperity. In Spanish, where the name is pronounced with an H sound at the beginning ala Jose, Jara is a flower name meaning "rock-rose". In Arabic, the meaning of "earthen water jug" relates it to both the earth and to water.

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.

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.

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.

Justina was the pre-Justine feminization of Justin, now a possible alternative to Christina. Oddly, while Justine feels like a name unto itself, Justina feels like a pinned-together feminization in the mold of Richarda or Benjamina. Still, it may appeal as one of the unusual-yet-familiar girl names starting with J.

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.

But what happens when Jeune grows vieille.

Fine in France, but here it means vegetables sliced into thin strips.

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

Love the name wren but need something not quite so trendy? Consider Jedda. Jedda is derived from the word 'djida' meaning "wren" in the language of the Noongar people of Western Australia. Jedda was also the name of the eponymous heroine of the film "Jedda", which was one of the first Australian films to be shot in color and was the first to be shown at the Cannes Film Festival (it was nominated for the Palme d'Or). The perfect name for nature enthusiasts and film buffs alike.
