Maybe it's because she shares that winning -elle sound with Isabel and Bella, but Estelle is no longer seen as a muumuu-wearing canasta player of a certain age (think George Costanza's mother on Seinfeld or Joey Tribbiani's talent agent in Friends). This could be in part thanks to the young Royal Couple of Sweden, who chose it for their firstborn daughter, or the single-named British R&B singer. It reentered the US Top 1000 in 2012 after a nearly fifty-year absence.

Elena is at its most popular point ever in the US, thanks to its cross-cultural appeal and the overall popularity of El- names. It's more international than Ellen or Eleanor, but still accessible.

Helena is one of those classic names that just misses making the US Top 1000 girl names for its entire history, falling off for a single year in 1992. Since then it's been drifting lazily up the charts, and makes a perfect choice if you want a name that both fits in and stands out.

Nell, once a nickname for Helen, Ellen, or Eleanor, is a sweet old-fashioned charmer that is fashionably used today in its own right. While Nell is perfectly in tune with contemporary vintage name style, it hasn't taken off the way some of its sisters have and so maintains an air of distinction. Use Nell or Nellie as a short for any name from Eleanor to Penelope or just name her Nell.

Xavier originated is use as a given name after Saint Francis Xavier, cofounder of the Jesuit order, who got his name from the Spanish-Basque village where he was born. His birthplace was Javier, the name of which was derived from the Basque place name Etxeberria, meaning "castle" or "new house."

Nova has the feel of both newness, from its meaning, and great energy as an astronomical term for a star that increases suddenly in brightness before fading.

Lucia is a lush, rich Latinate equivalent of Lucy, popular in Spain and throughout Latin America and also a cross-cultural favorite. You might be surprised to know that Lucia has ALWAYS ranked among the Top 1000 girl names in the US, though she's really taken off only since the turn of this century.

Alora combines a number of stylish elements: the pretty Al- beginning of Alice, Alessia, and Alma, the -ora ending of Aurora, Elora, and Nora, and a multicultural feel, owing to its various origins. A Top 250 name in the US and in England and Wales, around 1370 American babies received the name in a recent year.

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.

Albert has acquired a new gloss as one of the top royal baby boy names, a considerable upgrade from its serious, studious image (think Einstein, Schweitzer).

This old Scottish form of Helen has had quite a history, going from appearing as one of the shining heroines of the Arthurian legends, the princess who fell in love with Sir Lancelot and became the mother of Sir Galahad, referred to as 'Elaine the fair' and 'Elaine the lovable', to being the name of the most famous of New York's celebrity restaurants, to being the archetypal New York neurotic on Seinfeld.

Callahan, the simpler spelling of Callaghan, is a rhythmic jig of a name whose history harks back to the ancient King of Munster. In the Dirty Harry movies, the Clint Eastwood character is Harry Callahan.

Helen is a name that has connoted beauty since ancient times – Helen of Troy was the the mythological "face that launched a thousand ships," over whom the ten-year Trojan War was fought.

The multicultural Yara is a sweet but substantial choice that could make a more unusual take on Sara and also work in multiple languages. Popular in Portugal, The Netherlands, and Switzerland, familiar in the UK and France, it entered the US Top 1000 in 2017 and has been climbing the charts ever since.

With mythological names rising, the handsome son of Zeus and god of medicine, music, and poetry among many other things might offer an interesting, and melodic option. Similar in style to Atlas and Atticus and similar in sound to Arlo, Paolo, Paul, and Ollie, Apollo entered the US Top 1000 back in 2012, and was propelled upwards after it was chosen by Gwen Stefani and Gavin Rossdale in 2014.

May is a sweet old-fashioned name that hasn't been on the national charts in several decades, but is definitely sounding fresh and springlike. Parents are beginning to see it once more as one of the prettiest middle name options. May was as high on the list as Number 57 in the 1880s; it's now 228 on Nameberry.

Aaron is a name of subtle contrasts: an unusual spelling that is easily recognizable; a solid Biblical choice that doesn’t feel exclusively tied to religion; a well-established name for boys but sometimes confused with the girls’ name, Erin; used internationally but with notably different pronunciations; classic like Andrew but not out of place with recent favorites like Weston or Jayden.

An attractive French word name known here via former child TV star Soleil Moon Frye, aka Punky Brewster. It started to be lightly used in the U.S. in the 1920s and is now attracting some attention as both a sunny nature and an international word name. It's currently in the Nameberry Top 500.

Now that it's no longer fashionable for girls, Robin is rising for boys again. Robin Hood, Robin Williams, Christopher Robin, and Robin the Boy Wonder are all male namesakes, after all. It reentered the US Top 1000 boys names in 2015 for the first time since 1999 and continues to bounce around the lower end of the Top 1000.

Nadia, an accessible Slavic favorite, has a strong run of popularity in the US in the early 2000s, partially thanks to the character on Lost called Nadia but actually named Noor, but it's since slumped down the rankings. An earlier inspiration was Romanian gymnast Nadia Comaneci, who won the 1976 Olympics.
