Mary Peter James and John

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.

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.

The traditional German spelling of this name, used by Goethe, Bach and many other luminaries.

Johanna is the version of this name used in Holland, Germany, and Scandinavia. The extra h makes Johanna a slightly more dignified version of Joanna.

An Old World name that might have a chance to rise again with other ancient and worldly forms. Be sure to say yo-HAHN-es.

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.

Juan, the Spanish version of John, is ubiquitous in the Spanish-speaking world, and is familiar internationally via such references as Don Juan and San Juan.

Juana has not achieved the popularity in the U.S. of the male version Juan. Whereas Juan has made it almost to the Top 50 on the U. S. hit parade, sister Juana has barely entered the thousand most popular.

Pervasive in all Spanish-speaking cultures, Juanita, like Juana, has not emigrated.

This pet form of Helena and other ena-ending names, long used as an independent name, is attracting notice again as an option both multicultural and simple. Lena was a Top 100 name from 1880 to 1920.

Lucia is a lush, rich Latinate equivalent of Lucy, popular in Spain and throughout Latin America and also a cross-cultural favorite. You might be surprised to know that Lucia has ALWAYS ranked among the Top 1000 girl names in the US, though she's really taken off only since the turn of this century.

The French spelling of Lucy feels particularly light and shimmery.

Lucille is a name that had long been overpowered by its link to Lucille Ball, with an image of tangerine-colored hair, big, round eyes, and a tendency to stage daffy and desperate stunts. But with the newfound craze for double-L names like Lily and Lila, Lulu and Luna, and as the choice of Lucille by hipster parents Maya Rudolph and Paul Thomas Anderson, Lucille is breaking free from its old clownish image, moving rapidly up the charts over the past decade after a long nap.

Lucius is an old Roman clan name that has lots of religious and literary resonance, yet is still vital today. It was the name of three popes, appears in several Shakespeare plays, and, like all the names beginning with 'luc' relates to the Latin word for light.It was one of a limited number of forenames used in ancient Rome, and because of its meaning was often given to boys born at dawn.

A versatile classic, Lucy is both sweet and solid, a saint's name, and the heroine of several great novels. First fashionable in England and Wales, Lucy is now a popular choice in the US, The Netherlands, and New Zealand.

Pronounced LOOSE, this name that refers to the Virgin Mary—"Our Lady of Light"—is one of the most widely used Spanish name for girls. Its sleekness and stylish final z gives it a modern appeal, like sister name Lux. Nicknames and variations include Chitta, Lucecita, Lucelida, Lucelita, Lucha, Lucida, Lucila, Lusa, and Luzana.

Sophisticated and sweet, delicate but substantial, Madeleine is the classic French variation of Magdalene.

Madeline, a lovely name with a soft and delicate image, is an old-fashioned favorite that returned to favor in the 1990's, combining a classic pedigree with a cute nickname option: Maddy.

There's only one. Okay, two.
