 The pre-Norse Gaelic name, as recorded by Adomnán was "Airthrago" or "Arthràigh", meaning 'foreshore island', similar to the derivation of Erraid.It was leased to writer J. M. Barrie in the 1920s, who used it as a summer holiday retreat for himself, his foster sons Michael and Nicholas Llewelyn Davies, and a few of their friends.It was here that he wrote a screenplay for the 1924 film adaptation of "Peter Pan".
