Jessie has never been used as much as Jennie/Jenny, partly because it's a boys’ name as well (spelled Jesse), but it does have a friendly and unpretentious pioneer feel. In Scotland, it's found as an Anglicized form of Teasagh, itself a form of Jean, and is used as a full name. And in the rest of the world, Jessie may be short for Jessica or used on its own.

Probably due to its nursery rhyme association, Jill has the perpetual air of a rosy-cheeked tot -- even though it is one of the oldest names on the roster, a medieval variation on the Roman Julia. The pairing of Jack and Jill to connote a generic boy and girl goes back at least to the fifteenth century. But can knowing Jill's history keep it from sounding like a cute mid-twentieth century invention? There may be some possibility of Jill making it back up the hill.

Every other little kid's name in 1957 but few Jameses are called Jimmy today; they're more often James or Jamie.

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.

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.

If you focus on the patience of the biblical Job, rather than his trials, the name becomes more usable. He was, after all, the Old Testament hero of the Book of Job, whose faith was severely tested by God but remained faithful. The name was was used by Puritans and Christian fundamentalists and can be found in the novels of Dickens, George Eliot and Robert Louis Stevenson..

Jocasta is a mythological name fashionably used in England, but mostly ignored here. She was the mother of Oedipus, King of Thebes, whom he (oops) unwittingly married. If you can ignore that small error in judgment, you'll find an interesting and attractive J name that's neither overused nor terminally dated.

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.

No competition for Jackson.

Jonah, the name of the Old Testament prophet who was swallowed by the whale, only to emerge unharmed three days later, is increasingly appreciated by parents looking for a biblical name less common than Jacob or Joshua, yet not too obscure. Plus, Jonah comes with a ready-made nursery-decorating motif.

Jonathan was derived from the Hebrew name Yehonatan, eventually contracted to the modern Yonatan, meaning "gift of Jehovah." It comes from the elements yeho, in reference to God, and natan, meaning "to give." In the Old Testament, Jonathan was the valiant eldest son of King Saul, and it was his friendship with brother-in-law David that gave rise to the expression "Jonathan and David" to describe devoted, steadfast friends.

Quintessentially common last name makes distinctive if problematic first, given to nearly 100 babies in the US in the most recent year counted.

Joseph is one of the most classic names in American nomenclature, popular with parents from many ethnic backgrounds and having dual-religious appeal.

Josephine, with its large measure of class and character and a gently offbeat quality, has been on a gentle uphill climb in the US for over 30 years, now ranking in the Top 100. With an intriguing number of vivacious nicknames, from Jo to Josie to Fifi to Posy, Josephine is a Nameberry favorite.

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.
