The Selection themed names

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.

A variation of Jameson. Both names have climbed in popularity in recent years, though Jameson remains the preferred spelling.

It's far cooler to drop the first syllable and go for Elle.

Jenna was first noted on the 1980s TV series Dallas, later associated with one of the First Twin Daughters. Jenna is still being used, but no longer feels much fresher than Jennifer. You can also spell it Jena, but then many people will pronounce it jeen-a, as in Gina.

This one-time trendy form of Jeremiah hovered just outside the Top 25 throughout the 1970s and 80s.

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.

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.

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.

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.

Justin has been widely popular since the 1980s, when parents were seeking a fresher 'J' boys’ name to replace Jason, Jeremy and Jonathan. It's been dipping in popularity a bit in recent years but it reached as high as Number 9 in 1990. At this point it's Justin that is suffering from overexposure.

A popular member of popular family: Kadin, Kaeden, Kaiden, and Kayden -- along with Caden, Caiden, and Cayden, as well as Cade and Kade.

Kamber takes Amber into the 21st century, particularly with the Kardashian-ized K spelling.

Katherine is one of the oldest, most diverse, and all-around best names: it's powerful, feminine, royal, saintly, classic, popular, and adaptable. Long one of the top girls' names starting with K, Katherine has now been unseated on the popularity list by upstarts Kennedy and Kinsley, but a dip in popularity only adds to its charm.

The -leigh suffix seems to be losing its luster; several names in this category, including Kayleigh, Kyleigh and Ryleigh, peaked in popularity a few years back but have since lost quite a bit of ground.

Keller is a German surname that originated as an occupational name for a cellar or store master. It may be an honorific for deaf-blind author and activist Helen Keller.

Kenna is the Scottish version of Kendra, both of which are feminine versions of Kenneth. Used in the TV show Reign for one of the supporting characters.

Variation of Gertrude.

Actress Kirstie Alley popularized this short form that's been off the popularity register for a decade.
