Despite its distinguished pedigree and popularity in Israel, Disney's Little Mermaid cartoonized Ariel in the US, at least in some people's minds. But it was used for a male character in Shakespeare's The Tempest centuries ago.

 More recently, cool short form Ari has come into prominence via the character in Entourage, plus its similarity to short, breezy Biblical names like Levi and Eli. 

 Though Ariel has been on the rise for boys in recent years and flat for girls, the gender divide still leans heavily toward the feminine. But with parents increasingly drawn to uncommon Biblical boy names – especially those with that strong and gentle -iel ending – we think that gap could be set to narrow in the coming years.

Ariel

Strongly associated with the city of Tel Aviv. For girls, may be lengthened to Aviva; for boys, might be better abbreviated to Avi.

Daniel is one of only a handful of male names that sounds both classic and modern, strong yet approachable, and popular but not cliched. It also has a solid Old Testament pedigree. The only real downside: There are about 10,000 Daniels named each year, making it a less than distinctive choice. 
 
Daniel is derived from the Hebrew name Daniyyel, from the elements din, meaning "judge," and ’el, "God." The Book of Daniel in the Old Testament describes the Jewish prophet’s life of captivity in Babylon and visions of the last days of Earth. 
 Daniel was the name of one of the greatest biblical heroes, with the inspiring story of the prophet whose faith protected him when he was thrown into a den of lions. Yet Daniel does not seem as solemn and weighty a name as other Old Testament names like Abraham and Ezekiel. 

Popular since the days of Daniel Webster and Daniel Boone,
Daniel is a perennial favorite, in the Top 15 <a href="https://nameberry.com/boys-names">names for boys</a> every year since 1972. Daniel ranks first among all <a href="https://nameberry.com/search/boys-names/d">baby names starting with D</a>. 

Daniel's appeal is international, from Ireland to Israel, Finland to Chile. And its nicknames—Danny and Dan—make it sound even friendlier, though, as with other classics, many modern parents are opting to use the name in full.

Daniel

This Biblical name was rising dramatically for boys, but has plateaued in recent years. Although it's more popular for girls, it's a delightful unisex choice. Eden is one of the <a href="https://nameberry.com/popular-names/france">Top 100 Boy Names in France</a>.

The patron saint of comedians and dancers (also known as St Vitus) has a name that is both the ultimate everyman, and has a hint of British aristocracy. In the States, Guy was most popular in the 1950s. Now he hovers steadily below the Top 1000, in the sweet spot of familiar but not overused. With the meteoric rise of Kai, Guy may have potential with parents looking for a more classic name with a similar sound.

Noam is an underused modern Hebrew name with any number of attractive attributes attached to its meaning; it doesn't have the biblical weight of Noah, but could make a more distinctive alternative to that popular choice. Noam is a Top 10 boys' name in Israel. Noam is also a place-name in south Israel, where it is sometime used for girls. Its most prominent bearer is the distinguished linguist and social activist Noam Chomsky (born Avram Noam).
 Noaz is an even more unusual Hebrew choice.
