Alda's brother name Aldo has been a mainstay of the U.S. popularity chart for decades now, and the related Alden is soaring up as well. This version has never really caught on. (Maybe it's the association with Alan Alda: great actor, unlikely namesake for a little girl.) However, there is possible hope now that Alba and Alma are on the rise. Aida and Arden are more familiar alternatives.

Alejandra, the Spanish form of this popular and multivaried name, has fans both in and outside the Latino community. Still, it has lost ground since its peak in the 1990s.

Alena is a modern variant of Helen. Alena might also be a spelling twist on the Slavic Alina or a long form of Lena.

Young Canadian pop singer Alessia Cara has given this spicy-sounding name a new lease on life, propelling it into the Top 1000 in 2016. (It was one of the year's fastest-rising girls' names.) The main risk is that it feels so close to Alexa, Alicia, Alexis and Alyssa-- all becoming overused -- that it could be mistaken for one of those more familiar names.

A form of Adelaide (and therefore related to Alice, too) used in the Netherlands. The country's first female physician was Aletta Jacobs. In the USA, Aletta is rare, but on a slight upward trend. It fits perfectly into the sweet spot of being deep-rooted and straightforward, yet barely used, and has Etta and Lettie as potential nicknames.

Alexa was a steadily popular modern classic until Amazon's virtual assistant Alexa was released in 2013. It remains relatively well used in the US despite this, though its standing keeps dropping for obvious reasons. Too bad, because it's a strong and pretty name (which is probably why Amazon used it.)

Alexandra fell out of the Top 100 for the first time since 1983 in 2015 but is still a popular choice. Strong, tasteful, and elegant, Alexandra remains a chic modern classic with a solid historic pedigree.

Alexandria turns Alexandra into a more distinctive place-name, in both Egypt and Virginia.

Alexandrina is the most elaborate and unusual of the Alex- girls's names.The real first name of Queen Victoria, who was given it in honor of her godfather, Alexander I of Russia (her childhood nickname was Drina), it would make a distinctive pick, even though some might find five syllables a bit much. It was particularly popular in Scotland in the 1930s.

This diminutive, similar to Alex or Alexis, has been yo-yoing in popularity since the turn of the 21st century.

Alia is the most classic and feminine form of Ali, one of the 99 attributes of Allah within Islam. Meaning "supreme, exalted, high, sublime", it is pretty, powerful and spirited.

The uber-popular nickname-name Ellie has led to the surge of all names that can be shortened as such. This includes Eliana, a current go-to for parents seeking a frilly name that shortens to a cuter option. Aliana is riding a similar wave, though this time the presumed nickname is Ali/Allie.

Alicia is a Latinized variation of Alice, a name ultimately derived from the German Adalhaidis. It emerged in the 19th century, but the 20th saw many spelling evolutions for Alicia, including Alecia, Alisha, Aleesha, and Alysha. Alyssa originated as a form of Alicia.

Alina has been drifting up the US popularity charts since the early 1980s, and now sits in in the Top 200. But Alina's real strength is in its international flexibility: The name ranks highly in a wide range of European, English speaking, and Latin American countries.

While Alivia may not have achieved the megapopularity of its mother name, it's still a widely used choice. Alivia combines the trendiness of A names with the trendiness of Olivia to create a choice that's slightly off the beaten track -- slightly being the operative word here. Is the distinction the initial A earns you worth a lifetime of explaining, "No, it's Alivia, with an A, not Olivia"? Your call, though ours would be no.
