Elva is a multicultural choice, being both an anglicization of the Irish Ailbhe and an feminine form of the name Alf, meaning "elf". Popular in the US at the beginning of the 20th century, it remained in the charts until the 1970s before falling out of favor.

Esti is most commonly a short form of Esther and Estelle, both making the big move from old lady name to cool young name. It's also a popular short form of the Basque names Estitxu and Estibalitz, or a name in its own right, meaning "sweet honey". In French Canada, it's an untranslatable swear word.

Oslo, the capital city of Norway, makes for an intriguing new place name, especially with its bookended O's, as in Otto and leads to cool nickname Ozzie. One Berry has already used it and we predict others will follow; in fact, stats suggest it is used eight times more often than it was a decade ago.

Arlo, an unexpectedly popular name for boys these days, is also finding new life as a girls' name. Its roots are primarily as an Irish or English surname, but it might also be a short form of the Spanish Carlos or Italian Carlo, forms of Charles.

This lovely name is best-known as the surname of eponymous Bronte heroine, Jane Eyre, and would make an appealing and distinctive middle name for the child of fans of that book. While the surname Eyre is found mainly in England, its origins are Norse and it's thought to derive from Norse settlers. Still, the status of the classic books means Eyre deserves to stand proudly among English baby names.

Indie — as in indie films — is the more girlish version of the name, but earthy, gender-neutral Indy is catching up slowly and steadily. Indy entered the Top 1000 for girls for the first time in 2023 after rising over 100 places. For a longer full name, vibrant Indigo remains more and more stylish each year.

Ilsa is remembered as the radiant but tragic heroine of "Casablanca," and it's having something of a European resurgence.

Elmo, like fellow Sesame Street characters Kermit and Grover, has a hard time being taken seriously. (It isn't easy being red either.)

This Scandinavian name was made famous in English-speaking countries as the name of the dog in the "Thin Man" series. Danish actress Asta Nielsen was another famous bearer. Asta can be considered as a short form of Astrid or Augusta.

Edna is one of those names that, until what it seemed like a few minutes ago, felt so terminally frumpy that no one could imagine a parent choosing it for an innocent modern baby girl. But with the great upswing in names honoring ancestral family members, several of them being other four-letter, e-ending names, we wouldn't be so sure.

Commonly heard in its native country, and might get a boost here too, now that Alanis Morrissette has used it for her son Ever's middle name.

This Slavic form of the Norse name Helga is a classic in many Slavic countries, including Russia and Poland, where it currently ranks within the Top 100 girl names. It has historically ranked among the most popular names in countries including Ukraine, Latvia, Spain, France, Serbia, Greece, the US, and many more. Olga is a common name even in Scandinavian countries, such as Sweden and Norway, despite Helga being a more traditional choice. Olha is the uniquely Ukrainian variation.

Orlo is a name nobody ever heard of until the surprise popularity of the unrelated but similar-sounding Arlo. If Arlo can be a hit, why not Orlo? Why not indeed.

The name of the ship sailed by Jason in his search for the Golden Fleece is now more often used for starch, trucks, and heavy machinery.

Alya is most familiar in the US in its much-more-complicated form Aaliyah, the spelling used by the later singer. The traditional name of the star system Theta Serpentis, Alya is also an established Muslim first name and a Turkish place-name. It may also be a Russian short form for Alexandra or any other Al- name.

Ing was a powerful Norse god whose name inspired several modern variations -- though Inga has become a caricatured Scandinavian choice.

Este -- think Esme with a t -- comes to us via one of the rocking sisters in the musical group Haim. For long best known as the Esther diminutive used by cosmetics queen Estee Lauder, Este is a slimmed-down version that feels chicer for our star-struck times. While mother name Esther has Persian origins and impressive Biblical roots, it's a name used in a wide range of cultures.

Anja is one of the most international of several versions of Ann/Anna now being imported, also including Anya and Annika.

A true maverick of a girls' name — even more so with this spelling, the least common between Indie, Indy, and Indi.
