Eliza is a name with a wonderful combination of streamlined zest and Eliza Doolittle charm and spunk. It's a classic that's popular right now -- but not too popular.

Elsie is a sweet vintage nickname-name turned modern star. After a 30-year hiatus, Elsie started climbing the US popularity list 20 years ago and is still headed for the top.

Ella is a sweet, simple name that owes much of its current popularity to the popularity of other names, from Emma to Bella to Emily to Ellie.

Lily is the most popular of the popular delicate century-old flower names now making a return, thanks to its many irresistible attributes: a cool elegance and a lovely sound, a symbol of purity and innocence, and a role in Christian imagery.

Elise is one of those golden names that stylish but not TOO popular. Its appeal is due in large part to its French flair and to the love for El-names in general.

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.

Birdie was until recently a middle-aged Ladies' Club member wearing a bird-decorated hat --but now it's just the kind of vintage nickname (think Hattie, Josie, Mamie, Millie) that's coming back into style in a big way. Actress Busy Philipps named her baby Birdie (inspired by First Lady Lady Bird Johnson), as did soap star Maura West.

Billie is a tomboy nickname name, part of the growing trend for using boyish nicknames for girls and now destined for stardom along with its most famous contemporary bearer, music sensation Billie Eilish.

Lettie, also spelled Letty, is a nickname name that until recently, had rarely been heard since the 1950s. Now, this treasured antique is on the rise, fitting right in with the trend for old-fashioned, down-to-earth nickname, such as Lottie, Hettie, Hattie, Josie, and Maisie.

Lost in limbo for decades and decades, Elsa now stands a good chance of following along in the progression from Emma to Ella to Etta, thanks to the ice queen heroine who "Let It Go" in the wildly popular Disney movie Frozen. The name shot all the up to Number 286 (its highest ranking since the 1890s) in the year after the release of the movie, though it's now dropped back down the list in the US.

Combine the charming heroine of the movie Legally Blonde with supermodel Elle Macpherson and the trend toward all names beginning with "el"—Ellie, Ella, Eleanor—and you have one hit name.

Combine the popularity of Betty White and Mad Men's glamorous Betty Draper Francis, with the residual sweetness of Ugly Betty's Betty Suarez, and the result is an impending return of the name. It's got presidential cred via Betty Ford and feminist history through Betty Friedan.

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.

Elvis naming his daughter Lisa Marie and Nat King Cole's hit song "Mona Lisa" conspired to catapult one of Elizabeth's many offshoots to a high of #4 in 1970.

Although they could be easily confused, Elsbeth is a fairly unusual contracted German version of Elizabeth, while cousin Elspeth hails from Scotland. With its 'beth' ending, Elsbeth feels closer to the mother name.

The sweetest and most sensitive of the pet names for Elizabeth, now also one of the most dated.

Sweet but sleek, and distinctive, Liesel is an old German nickname-name for Elisabeth. It might have once seemed inextricably tied to to its country of origin, but now, like Elsa, Enzo, Saoirse, Freya, Soren, and Heidi, it leans more towards being international and European chic.

Ellis, a surname used sparingly as a first in the Wallace/Morris period, sounds new now for girls, as a gender-neutral alternative to Ella or Alice. It debuted in the US Top 1000 for girls in 2015.-- Ellis has always been in the Top 1000 for boys -- and seems to be headed straight up. One of the most popular gender-neutral names, currently there are two baby boys named Ellis for every girl.

Though the most famous Elia, screenwriter Kazan, was male, this name sounds like a spin on many popular girls' names, from Ella to Ellie to Isla and Leah. While the Italian pronunciation has the middle syllable as LEE, making it closer to the original Elijah would give the middle syllable a long I sound — eh-LYE-ah.

Elisa is one of the most appealing of this contingent of Elizabeth-related names. In the US, Eliza is much more stylish these days, but Elisa is very popular internationally — especially in Europe and Latin America.
