Jacqueline originated as a feminine form of Jacques, the French variation of James, and therefore Jacob. Jacob was ultimately derived from the Hebrew name Ya’aqov, and gets its meaning, "supplanter" from the story of Jacob supplanting his brother Esau as the first-born son in the Bible. Jacqueline was first used in France in the Middle Ages.

Jackson is one of those names that's much more popular than you think, coming in near the top of our annual Playground Analysis, which ranks names by grouping all their spellings together. Last year, more than 13,000 baby boys were named Jackson -- along Jaxon, Jaxson, Jaxxon, Jaxen, Jaxyn, Jaxsen, and Jaxsyn -- which counted together makes it the Number 5 boys' name.

Josiah—a biblical name with lots of quaint, old-fashioned charm—makes a much fresher sounding alternative to either Joseph or Joshua, combining the best of both. Josiah is among the several Biblical boys' names that have been on the rise this decade.

King David's father turned 1980s cowboy, Jesse is now down in popularity but still a Biblical classic, ranking in the US Top 1000 for its entire history. The name is associated with a wide variety of bearers, from outlaw Jesse James to Olympic athlete Jesse Owens to activist Jesse Jackson to current actors Jesse Tyler Ferguson and Jesse Eisenberg. The spelling Jesse is more usual as a boys' name while Jessie is more traditional for girls.

Jace may sound like only half a name -- it's usually pronounced like the first half of Jason though some may consider it a spelling-out of the initials J. C. -- but it's a popular choice for baby boys. Jace has been heard on such TV shows as Teen Mom 2 and Duck Dynasty.

Josie is jaunty and friendly: among the most winning of all nickname names. She's been on the Social Security list since records began being kept.

Juliette, pronounced with the emphasis on the last syllable, adds a little something extra to Juliet. In the past years it has been rising up the chart.

Though Jules hasn't been on the US popularity list in fifty years, it is a current hit in its native France—where it's currently in the Top 10—and we can definitely see it making a comeback here, being far more romantic than, say, Jim.

Joan was the perfect name choice for one of the leading characters on Mad Men, being a quintessential girls' name of the period. A Top 10 name in the 30s, a Top 50 name from the 40s through the early 60s, it was the fifth most popular name in the country for three years running and ranks as one of the most common names for girls in the 20th century. But alas, Joan hasn't even appeared in the Top 1000 for a dozen years, and these days it's primarily associated with Joans of the generation of Joan Crawford, Joan Collins and Joan Rivers--just a few of the noted Joans whose ranks also include the singers Joan Sutherland, Joan Baez, Joan Armatrading and Joan Jett. But it's possible that modern parents who are reviving Jane might move on to Joan, inspired by Joan Hollaway Harris.

In the Old Testament, Joel was one of King David's 'mighty men' and the name was taken up by the Puritans of the sixteenth century. In the mid 1960s, Joel entered the Top 100, and stayed there for about twenty years, as parents tried to jazz up and formalize old standby Joe by reviving this biblical name.

This one-time trendy form of Jeremiah hovered just outside the Top 25 throughout the 1970s and 80s. Though off its peak, it's still in the Top 300 in the US for baby boys, and might be considered a modern classic.

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.

Originally a feminine of John, Jean was popular in Scotland long before it found favor elsewhere, and had its most shining moment here in the era of Jean Harlow (born Harlean), ultimate symbol of silver screen glamour. Now, though there are many grandmas and even moms with the name, it doesn't seem all that baby-friendly. Though that could change, and Jean could join Jane.

Jonas has a slightly more grandfatherly image than the English version of his name, but that only adds to its retro appeal. And though it may lag behind Jonah in this country, Jonas is riding a huge wave of popularity in Europe, where it ranks highly in Germany, Switzerland, Austria and Norway.

Jordan became one of the top unisex baby names in the heyday of basketball's Michael Jordan, and is still among the most popular unisex names starting with J. The name was originally given to those baptized in holy water brought back by Crusaders from the River Jordan, the only river in Palestine, and the one in which Christ was baptized by John the Baptist.

Jasmine was derived from the Persian word yasmin, referring to the jasmine flower. Scented oil was made from the plant, and it was used as a perfume throughout the Persian Empire. Variants include Jazmin, Yasmin, Yasmine, and Jessamine.

Jason, the Number 3 name for the entire decade of the 1970s -- thus the title of our original baby-naming book, Beyond Jennifer & Jason -- is more likely to be dad's name now than baby's, but it's still a widely used name.

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.

The cool form of James in the 1970s and '80s for both sexes. Still a more stylish short form than Jimmy, though many parents will want to call James by his entire, not-very-long name.

Joanna derives from the Greek name Ioanna, which in turn came from the Hebrew name Yohannah. It is featured in the New Testament as a woman who accompanied Jesus on his travels and eventually reached saint status. Other names related to Joanna include Joan, Joanne, Johanna, and Jana.
