Names from my 52 books in 52 weeks challenge

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.

Jeremiah is a solid Old Testament prophet name that has gradually taken the place of the now dated Jeremy, Gerard and Gerald, joining other currently popular biblical 'iah' names like Josiah and Isaiah. In the Bible Jeremiah is a famous prophet whose story is recorded in the book named after him.

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.

Jessamine, a charming name occasionally heard in England, is just beginning to be appreciated in the U.S. as a possible successor to all the Jess names of the past. It's also spelled Jessamyn, as in Quaker novelist Jessamyn West, author of Friendly Persuasion--who started life with Jessamyn as her middle name.

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.

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.

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.

Joyce was once a boy name, but took off for girls during the mid-twentieth century, when it spent 1930 to 1947 in the Top 20.

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".

Cool and charming, with plenty of flair and sophistication, Julian manages to strike the balance between being a sensible classic and contemporary choice. Appealingly international, it is no wonder Julian is a rising star.

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.

Immortal through its association with the ancient Caesar (it was his clan name), Julius may still lag behind Julian, but is definitely starting to make a comeback, and in fact feels more cutting edge, in line with the current trend for Latin -us endings.

This pretty, updated Karen variation was introduced by the daughter of Al and Tipper Gore, whose name was inspired by Russian novel Anna Karenina.

Although the Kathryn spelling feels like a modern streamlining of this ancient royal and saints' name, it is in fact found back through history. At least one of Henry the Eighth's unfortunately wives sometimes spelled her name as Kathryn.

Friendly mega-popular short form of Katherine that has definitively replaced Kathy, Katie is often given on its own. Going forward, though, Katie is more stylishly clipped itself to the grownup Kate.
