Meaning and Origin

The name Arlo does not have one universally proven meaning. Many name references describe its meaning as uncertain. The strongest repeated explanation connects Arlo to Arlo Hill, a place name used in Edmund Spenser’s late sixteenth-century poetry.

A common interpretation says Spenser may have shaped Arlo from Aherlow, a real Irish place name. Logainm, the Placenames Database of Ireland, records the Irish form Eatharlach and the English form Aherlow for a place in County Tipperary [Source-2✅].

The Aherlow link is why Arlo is often explained as “between two highlands” or “low land between two high lands.” Discover Ireland gives this translation for Aherlow in its description of Gortavoher and the Glen of Aherlow area [Source-3✅].
