Quirky cool Arlo is now well and truly back. Last year it broke into the US Top 200 boy names and consistently ranks among the most popular boy names on Nameberry.

Leo is a strong-yet-friendly name that was common among the Romans, used for fourteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

Ari, the short form of Ariel (or any other Ari- beginning name, such as Aristotle) stands up better as a boys’ name than its progenitor does. It is also short for Aristotle, as in Onassis, and is a prominent character on TV's Entourage -- the uberagent Ari Gold.

A sweet and sophisticated nickname which feels fresh again after many years in style limbo. For literature lovers, it brings to mind Theodore "Laurie" Laurence from Louisa May Alcott's Little Women. Another famous bearer is English actor Hugh Laurie.
