Aiko is a very common Japanese name with a lovely meaning that is rarely heard outside the Asian community.

Softer and smoother than Alexander, this classic Spanish name for boys has made a seamless transition to this culture. Adding to its current impact: the Lady Gaga song Alejandro .

Armando takes the flat-footed Herman and makes it romantic. This is another of the Latin names we expect to be seeing more of.

Aurelio is an energetic Italian name rarely heard here, with an attractive aura. As the female version Aurelia gains greater notice, we expect to hear more from Aurelio too. In fact, Aurelio has recently entered the Top 1000 in the US in 2022. Next to follow might be latinate versions Aurelius and Aurelian.

Beau suggests someone devilishly handsome, with a large measure of southern charm—a nice image to bestow on your boy. Often solely a nickname in the past, it's now standing firmly on its own. Beau has been on the Social Security list non-stop since 1969.

Benno is a cool name in its own right -- there was a tenth century Saint Benno -- though it is also used as a lively nickname for Benjamin. Saint Benno of Meissen is the patron saint of anglers and weavers and, strangely enough, alliteration.

We all heard it on Seinfeld as the long-concealed first name of Kramer, then considered a punchline. Now some pioneering parents are embracing this expansive Greek name, which makes a creative and cool choice for a baby. Influential celebrity couple Scarlett Johansson and Colin Jost chose it for their son, born in 2021, which will likely drive Cosmo up in popularity. In the UK, it currently ranks within the Top 1000 boy names and is trending upwards.

One of those ultimate cool-girl names, played by Keira Knightley in a movie about a supermodel-turned-bounty hunter, but kids might associate it with the game.
