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.

Arlo, an unexpectedly popular name for boys these days, is also finding new life as a girls' name. The first name Arlo may be rooted in the surname Arlow or the place name Aherlow, meaning "between two highlands". As a surname, it also has roots in a place name meaning "rocky hill".
