The author believes that the Rock of Doon may well have served for the inauguration of the O'Donnells, at least until 1258 when the bishop of Raphoe summoned Domhnall Og Ó Domhnaill to be inaugurated in Raphoe cathedral. In subsequent years the ceremony was transferred, at least in part, to the church of Kilmacrennan.
