If you like Isla . . .

This Anglicized spelling makes the pronunciation of Ailís or Aileas – the Irish and Scottish forms of Alice, respectively – slightly more obvious to English-speakers. Ailis or Aileas are more authentic spellings, but may be fighting a losing battle against the influence of Billie Eilish.

Ailsa is a traditional Scottish name for girls related to a rocky island in the Firth of Clyde called Ailsa Craig. It might make an interesting alternative to the outdated Ashley or overly popular Ella, and could also be thought of as a relative of Elizabeth or Elsa.

Alaia, a fast riser in the US, sounds just like several other popular stylish names, many of them with different origins and meanings. There's Arabic Aaliyah, like the late singer, and the Hebrew Aliya and the Sanskrit Alaya. Azzedine Alaia is a high-fashion Parisian designer of Tunisian origin.

Alsie and Alcie feel more baby-ready now that names such as Elsie, Elsa, and Isla are becoming popular again. Mother name Alcina was an operatic sorceress who turned men into animals and trees.

Alula, the palindromic name of the first double star to be identified as physically related to its twin, would make the perfect name for a first-born twin. Ideas (we're only half joking) for the second born: Aviva, Aziza, Otto. Alula is reminiscent of the unusual name chosen by Isla Fisher and Sacha Baron Cohen for their second daughter: Elula, a month name from the Hebrew calendar.

This pretty and uncommon Basque name is all but unheard of in this country. Amaya is a spelling variation as well as a similar Japanese name meaning "night rain." With the newfound popularity of Amara and Amora, Amaia and Amaya are among the Spanish names for girls we'll be hearing a lot more of in the US.

Anya is a Russian variation of Anna, which came from the Hebrew name Hannah. Anya is the form found most frequently in Russia, Poland, and other East European countries, while Anja is the spelling usually preferred in Germany Norway, Denmark, Germany, Sweden, and The Netherlands. In the Hungarian language, Anya also means mother.

This Irish variation of Isla might prove challenging outside the United Kingdom, but looks beautiful and could be a good way to make the name Isla, which is becoming more common, feel a bit more unique.

Ava is one of the prime examples of a modern classic name, rising thought the course of a generation into the Top 10, where it has lingered for nearly 20 years.

Bright, fresh, and sunny, Ayla is a fashionable choice for girls. Reminiscent of other trending names such as Layla, Isla, and Ava, Ayla has recently found its place in the Top 100.

Brisa is commonly used in Latino families, all but unheard of in others.

Caia Caecilia was the Roman Goddess of fire and women. The name Caia would make a truly fresh alternative to the flagging Maya, with which it rhymes.

Melodic and lively, Delilah has cut itself (mostly) free from its treacherous past to become a contemporary favorite.

A sweet and simple multicultural choice which has several different meanings and origins.

The Scottish Eileen was a midcentury darling that was on a long downward slide for decades. And then, in 2012, it took an unexpected pivot and has been inching upward in the US. The unrelated but similar-sounding Isla may have revived the taste for Eileen. Isla along with Lee and Lena might be nicknames for Eileen. Eileen is an Anglicized form of the Gaelic Eibhlin or Aibhilin, which is technically a form of to Evelyn/Aveline, but is also sometimes considered part of the Helen family of names. Aileen is the Irish version, less popular now than Eileen.

Long popular in Scotland, this attractive name is strictly-speaking the Gaelic version of Eleanor, but is also often considered part of the Helen family of names. After the Normans introduced it into the British Isles, it was transformed into Aileen or Evelyn. It has rarely been heard in the US, but it is slowly starting to be used here too.

Eilish is one of those Irish names that, thanks to a celebrity, has suddenly become much more familiar to English speakers. Irish-American singer Billie Eilish (Eilish is actually one of her middle names) introduced the wider world to this Irish name as actress Saoirse Ronan did with hers.

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.
