Agatha Christie Names

A cute diminutive of Jack, already technically a nickname for John, famously borne by Hong Kong actor, director and martial artist Jackie Chan.

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. There were nearly 17,000 baby boys named Jackson -- along Jaxon, Jaxson, Jaxxon, Jaxen, Jaxyn, Jaxsen, and Jaxsyn -- which counted together makes it the Number 3 boys' name.

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.

James is one of the classic Anglo-Saxon names, a stalwart through the ages that is more popular—and yes, stylish—than ever today. It recently came out Number 1 in a poll of America's favorite boys' baby names, and is the most common male name, counting people of all ages, in the US.

No, we don't consider Jane too plain. In fact, for a venerable and short one-syllable name, we think it packs a surprising amount of punch, as compared to the related Jean and Joan.

Janet started as a pet form of Jane but has long been used independently. Jane is a feminine form of John, which derived from the Hebrew name Yochanan. Janet can also be considered a variation of Jeannette, a derivative of Joan and another feminization of the name John.

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.

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.

The name of the third U.S. President sounds, like Harrison and Jackson, more modern and stylish now than its root name. Used as a first name long before our surname-crazed era, Jefferson was most famously used as a first name by the President of the Confederacy, Jefferson Davis, which may justifiably make you not want to use it. Jefferson is the middle name of another Prez, William Clinton.

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.

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.

Peaked in the 1940s, but still an amiable classic, a la Joe and Tom -- though rarely used on its own.

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.

Joe is still the ultimate good-guy name, not at all diminished by its longevity or popularity or its everyman rep as Regular Joe, Cowboy Joe, G.I. Joe, Joe Exotic, Joe Blow, Joe Millionaire, Average Joe — and now President Joe (Biden).

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.
