Jennifer is the Cornish variation of Guinevere, which ultimately derived from the Welsh name Gwenhwyfar. It has been in use in the English-speaking world since the 18th century but came to prominence in the 20th. Playwright George Bernard Shaw chose Jennifer for the name of his leading lady in his play The Doctor’s Dilemma, which drew more attention to the name.

This one-time trendy form of Jeremiah hovered just outside the Top 25 throughout the 1970s and 80s.

Jerome has a bespectacled, serious, studious image, just like its namesake saint, who was a brilliant scholar. St. Jerome is the patron saint of students, librarians, and archaeologists.

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.

Jocelyn has gotten new life and popularity as a result of the current passion for lyn endings. Though it was a male name in medieval times, now Jocelyn couldn't sound more softly feminine.

One of the cute and bouncy nicknames so popular in the 1960s and 70s, but that hasn't made a comeback in the way Eames chairs and miniskirts have. Think of it as one of the original but now old-school unisex names starting with J, ala Jamie and Jessie.

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.

Still very Old European, conjuring up the image of a classical composer. But surprisingly, it's now been in the Top 600 in the U.S. since the turn of the 21st century, largely thanks to Heidi Klum and Seal's young son.

No competition for Jackson.

Jose is as widespread in the Hispanic community as Joseph and Joe are elsewhere in the U.S., though its numbers here are starting to decrease somewhat. Jose is one of those Spanish baby names that has never crossed over into the Anglo naming culture.

Joshua, a Top 10 name from 1983 until 2010, has dropped out of the Top 50 but manages to present a relaxed, attractive image, with a bit of the Old West mixed in with its biblical persona.

Jovan, the name of the supreme Roman deity, seems more extraterrestrial now -- and it's also firmly attached to a perfume label. Some parents may see it as a variation of Giovanni, the Italian for John. It is in fact the Slavic variation of John and may be an original way to honor an ancestral John.

Joy is from an older generation of word names, which also included Merry, Bliss, and Glory -- all of which exert a certain amount of personality pressure on a child. One interesting name that means the same thing: Chara.

Julia was an ancient Roman imperial name given to females in the house of a Julius, as in Caesar. Its origin is shrouded in history, but possible roots include Latin iuvenis, meaning "youthfu"; Greek ioulos, meaning "downy-bearded"; or Jovis, a form of Jupiter, which means "sky father".

Justin has been widely popular since the 1980s, when parents were seeking a fresher 'J' boys’ name to replace Jason, Jeremy and Jonathan. It's been dipping in popularity a bit in recent years but it reached as high as Number 9 in 1990. At this point it's Justin that is suffering from overexposure.

This sweet and loving name, favored in recent years by a mix of Hispanic-American parents and Bob Dylan fans, was chosen for her daughter by TV actress Melina Kanakaredes.

Kay, a cigarette-smoking, nightclubbing name of the 1930's, could be ready for a comeback along with cousins May/Mae and Ray/Rae.

This member of the aden/ayden extended family is a popular choice not only in the US but across the pond in England, Wales and Scotland as well. Angie Everhart has a son named Kayden Bobby.
