Ellie first took off in the UK—yes, in this nickname form—and this warm and friendly name has also become hugely popular here. In 2011, Ellie entered the US Top 100 girl names for the first time and has remained near the top of the charts ever since.

This pet form of such names as Winifred and Edwina and Gwendolyn has loads of vintage charm, a la Millie and Maisie, with a decidedly winning vibe. And it just got celebrity cred as the baby daughter of Jimmy Fallon.

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.

Charlie is a friendly, boyish nickname name now used slightly more frequently for girls than boys, with over 2200 baby girls named Charlie last year versus about 2100 boys. That makes Charlie one of the most evenly-balanced and most popular unisex names around today.

Bea is a former old lady name that's cute again as a short form — and is now beginning to stand on its own. Bee is a variation that, like Bea, can work as a diminutive for any name that starts with the letter B, or in the middle. Bea actually stood alone on the popularity lists for four years at the beginning of the twentieth century — and it could happen again.

Maggie is a cute, earthy short form that has been in style for several decades now, still sometimes used as an independent name by such parents as Jon Stewart. First used in Scotland, it got a large bump in popularity via the 1971 Rod Stewart hit song "Maggie May." Today's Maggie might just as well be short for a more adventurous name such as Magdalena or Magnolia as for the classic Margaret.

Maggie Gyllenhaal was born Margaret.

Frankie is a vintage nickname name for girls, with a down-to-earth country feel. It's one of the hottest boyish nicknames for girls, in the forefront of that trend.

Flossie was an extremely popular Florence nickname that was used independently in the early twentieth century, given to over five hundred girls per year a century ago. Appealing, sweet as candy floss, though perhaps a too cutesy for some, Flossie was chosen for nine girls in England and Wales in a recent year.

Though not much in use, still retains a cozy Little House on the Prairie-type pioneer feel.

Minnie was wildly popular at the turn of the last century — it was the fifth or sixth most popular name throughout the 1880s — but is completely obscure in the US today. Blame Mickey's girlfriend. Regardless, it's possible that the up and coming trend toward old-fashioned nickname-names — think Maisie, Mamie, Millie — may give Minnie (all on its own, not as a short form of anything) a new moment in the sun.

Lou is usually a short form of Louise, Louisa, or Lucy in English-speaking countries, when Lou is used for girls at all. But in France and Germany, it's a fashionable choice all on its own, sure to gain even more widespread style credibility since Heidi Klum and Seal chose it for their daughter.

This Elizabeth nickname has a decidedly retro feel--think Betsy Ross and the Betsy Wetsy doll-- once seen as a perkier, younger-sounding alternative to Betty. But with Betty on the brink of a comeback, pigtailed Betsy could return as well.

Cute boyish short forms like Teddy and Frankie and Billie are in some ways a relic of the past, of the days before unisex names, when girls were given feminized versions of their father's names, but they are starting to come into their own again.

Coco came to prominence as the nickname of the legendary French designer Chanel (born Gabrielle) and has lately become a starbaby favorite, initially chosen by Courteney Cox for her daughter Coco Riley in 2004. At first it was the kind of name that the press loves to ridicule, but we predict Coco's heading for more broad acceptance and even popularity.

Boyish nicknames for girls are all the rage — just look at the success of Charlie, Frankie, Stevie, Billie, and Scottie in recent years. Andie has history as a nickname for Andrea, popularized by actress Andie Macdowell. This name has major cool girl appeal through Kate Hudson's portrayal of Andie Anderson in How to Lose a Guy in 10 Days and Molly Ringwald's of Andie Walsh in Pretty in Pink.

A spunky boyish diminutive in the vein of Frankie, Billie and Charlie, but far less popular in the US. Georgie could be a nickname for Georgia, Georgette, Georgina or Georgiana – or just use it as it is, as over 90 sets of American parents did in 2021.

Through all the years when Betty, Betsy, Beth, Liz, and Lizzie were the Elizabethan nicknames of choice, the bubblier Libby was set aside, but today it may be the most modern of all—it has already made a strong comeback in England and Wales, where it ranks Number 139.

Joining the likes of Coco and Fifi, Gigi has a style but some may feel it lacks substance. Model and TV personality Gigi Hadid (born Jelena) has likely drawn attention to this name, while designer Cynthia Rowley may have inspired parents to use it as a given name by choosing it for her daughter.

The longer Isabella stays in the Top 10—and it's been there for more than a decade—the more we hear the nickname Izzy (especially if we watch Grey's Anatomy). it's just a matter of time before it stands on its own, as it has as a first name for the daughter of Eddie Murphy and Paige Butcher.
