Irati, almost unique, should be due to a mistaken transcription of Irato, who is typically Sicilian from Milazzo in the Messina area, with appearances also to Gualtieri Sicaminò and Barcellona Pozzo di Gotto, also in the Messina area, and which could derive from the Italianization of the name Basque Irati, but we cannot exclude the possibility that it may instead derive from a nickname originated from the ancient Greek verb ??????? erathizo (provoke).
