Arlo is associated with the meaning “Fortified hill or barberry tree” — a beautiful sentiment to see brought to life in your child’s room.
Arlo carries an air of mystery when it comes to its precise roots. Most name scholars point to Anglo-Saxon origins, where it likely meant "fortified hill" from the Old English elements for army and hill. Another theory traces it to Spanish and Italian traditions, where Arlo appears as a place name in literature and geography. The name also surfaces in medieval Italian poetry, giving it a romantic European thread alongside its English connections.
