★ What does Arlo mean?

Uncertain

English, first used by the poet Edmund Spenser for a hill in the Galtees, apparently from Aherlow.

Say it right

ARlo

The story of Arlo

Arlo has no settled meaning. Its earliest known use is in Edmund Spenser’s poem The Faerie Queene, where Arlo Hill is the place the gods gather for a great debate. Spenser seems to have coined the name. Arlo is also found as an Italian name, which some connect with Carlo, but that link is not well documented.

Spenser’s hill is in Ireland. He lived at Kilcolman in north Cork, and the historian P. W. Joyce argued that Arlo Hill is Galtymore, the highest of the Galtee Mountains, with the name taken from the Glen of Aherlow beside it.

Arlo first reached the CSO list in 2009 and grew quickly after 2015. Its best year so far was 2024, when 118 boys were named Arlo and it reached number 48. It is a little more popular in Northern Ireland, where it reached 40th in 2023.
