Underused names

The origin of the name Aaron is debated—some say it was derived from Hebrew, while others claim it originated in Ancient Egypt. In the Old Testament, Aaron, the older brother of Moses who was appointed by God to be his brother's spokesman, was the first High Priest of the Israelites. The Hebrew version is Aharon—in Yiddish it can be Aaran—and the name appears in Arabic as Haroun or Harun.

French Canadian pop star Avril Lavigne has put the spotlight on her name.

Belle has nothing but positive associations, from "belle of the ball" to "Southern belle" to the heroine of Disney's Beauty and the Beast. As if this weren't enough good things, Belle is also one of the most familiar and usable names that mean beautiful. Though it has been overshadowed by the Twilight-influenced Bella and longer forms like Isabella and Annabella, Belle has its own Southern charm and would make a pretty choice as a first or middle name.

Like the French author with whom the name is most closely associated, Colette is a chic and charming name that is being rediscovered. After disappearing for nearly 30 years, Colette rejoined the Top 1000 in 2012 at Number 659 and has continued to rise since then.

Farah is a soft and lovely Arabic name, best known here in this original spelling via the last Empress of Iran, Farah Palavi. It's currently a Top 250 name in both France and the Netherlands, which both have a large Arabic-speaking population, and appears in at least two video games.

Hadley, most famous as the name of Ernest Hemingway's first wife, is more sophisticated, professional, and modern than cousins Harley, Haley, or Hayden.

Louisa, a quaint vintage name, is an example of the idea that these days, old-style girls’ names are more fashionable when they end with an a rather than with an e, as in Julie/Julia, Diane/Diana.

Louisa reentered the US Top 1000 in 2014 after a 45 year absence.

Thanks to Mariah Carey, everyone now knows this name – and is aware that Mariah's pronounced with a long i – just as Maria was in the Jane Austen era. And though Mariah now sounds modern, it was heard as far back as 1550 in Great Britain.

Pretty feminissima name that never became as overused as cousin Melissa. The more streamlined Maris is a more modern sounding option.

Miranda, a shimmeringly lovely, poetic name that was invented by Shakespeare for the beautiful and admirable young heroine of his play, The Tempest, is still a recommended choice even though its popularity peaked in the 1990's, partially as an antidote to Amanda.
