The new Maia, the next Kayla, Kaia has been on the charts since the year 2000. You might see it as a female form of the also-rising Kai, which means sea in Hawaiian and is sometimes used for girls as well, or as a Kardashianization of the ancient goddess name Caia.

Kate, in the headlines via Catherine Middleton aka the Princess of Wales, has been as pervasive as Kathy was in the 1950s and 1960s, both as a nickname for Katherine and Kaitlyn and as a strong, classic stand-alone name.

Kit is a crisp, old-time nickname with plenty of spirit and style. In the UK it's a rising star for boys, while in the US, it is trending upwards for girls too.

Kiara can be considered a variation of both the Italian name Chiara and the Irish name Ciara. Chiara is the Italian form of Clara, meaning "bright" or "clear," while Ciara is the feminine form of male given name Ciar, derived from the old Irish cíar, meaning "dark."

Kara and the soundalike (though not necessarily related) Cara are among the most multi-cultural names around. Cara has roots in Latin, Italian, Irish, Spanish, and Portuguese, and Kara can be viewed as simply as K-starting version of Cara.

Kayla is a modern invented name that emerged in the late 1950s. It may have been inspired by the similar sounding Michaela, though it could equally have come about as a combination of the then popular name popular name Kay and the familiar -la suffix.

Though such cognates of Kira as Keira, Kyra, and Ciara are increasingly popular throughout Europe and in the U.S., this Cyrus relative has a different root.

Light and glittery, but with plenty of spirit, Kinsley has risen quickly into the US Top 100. Balanced between preppy and cutesy, it feels like a fresh alternative to Kelly, Kaitlyn, or Kimberly.

Karen, a once sweet Danish import, was so popular during the baby boom (Karen was Number 3 in 1960) that it's become a mem in recent years, representing a hostile white woman—one who usually wants to speak with the manager.

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.

This endearing nickname name is one Katherine pet form that predates all the Kathys and Katies, having been fairly common in the eighteenth century. With the current mini-craze for animal-related names, Kitty is sounding cute and cuddly again—she's already jumped back onto the U.K. list, at number 199.

Keira is an attractive girls’ name that's gotten a huge boost from the meteoric rise of Keira Knightley. Original spelling Kiera, which relates more directly to the male Kieran, was the more popular form until the rise of Keira Knightley reversed the order. Both are Anglicized versions of the Irish Ciara.

Kathleen is the early Irish import version that came between Katherine and Kaitlin, and which hasn't been used in so long it's almost beginning to sound fresh again. It was a surprise pick by one of the hip Dixie Chicks, Martie Maguire. Kathleen was a Top 10 name from 1948 to 1951, and it is the subject of several old sentimental songs, such as "I'll Take You Home Again, Kathleen."

Popular pop name, inspired by Australian singer Kylie Minogue. It was at its height in Australia in the 1970s and early 80s; often cited as a Noongar name meaning "boomerang".

Kyle is stronger and sharper, though many parents will prefer the more distinctly feminine Kyla for their daughters. Kyla may owe much of its popularity to trendy cousin Kayla.

Kiki is one of the Coco-Gigi-Fifi-Lulu bohemian-type French nickname names from the turn of the last century, which have endless energy and sparkle.

Kiki can be a nickname for any name beginning with the K sound, from Katherine to Christina to Kayla.

This appealing multi-cultural name, pronounced KYE, is beginning to be used for girls as well as boys.
