Old-Fashioned, Vintage, Retro, Classic, Eclectic, Unusual and Uncommon Names for Girls

Karen is a Danish diminutive of Katherine, an English name derived from the Greek Aikaterine. The etymology of Aikaterine is contested, but generally considered to have arisen from the Greek root katharos, meaning "pure." Kaja is a related name, as it is another Danish variation of Katherine.

Karoline is the form of the classic Caroline commonly used in Germany and throughout Scandinavia, where it is popular. It's an acceptable if not tradition spelling variation, given to nearly 100 baby girls in the US last year, versus more than 3000 named Caroline.

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.

This is the spelling that old-time film star Katharine Hepburn used, and it's still favored by fans wanting to reference her classic strength and beauty. But in general, it's losing ground to Katherine and even Ms. Hepburn's own favorite short form, Kate.

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.

Variation of Katherine.

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."

Annette Bening and Warren Beatty bestowed this name on their daughter in honor of his mother.

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.

There are lots of Kathy moms and grandmas but very few babies, most of whom are now called Kate or Katie.

The hurricane blew this one out of the realm of possibility.

Kay, a cigarette-smoking, nightclubbing name of the 1930's, could be ready for a comeback along with cousins May/Mae and Ray/Rae.

Kaye and its more popular sister Kay, once common short forms of the perennially popular Katherine, are now on the endangered list, given to fewer than 50 baby girls each year. But maybe that makes them prime for a comeback? Rarer than Kate, in any case.
