From SurnameDB: This interesting name, also found as (O)Corry, (Mac)Corry, (O)Corr and Curry, is of Irish origin and is the Anglicization of the Gaelic 'O'Corra', which translates as the descendant of 'Corra' (the 'O' denoting son of), a personal name from 'corr', a spear, or pointed object. Corr is the more modern form, and is much more numerous in Ulster than elsewhere, and many of the Corrs of Tyrone and Derry are descended from Gilla Corr ... , whose son is perpetuated in the townland of Ballykilcurr, near Maghera. People of the name Cor and Corre were established in Counties Tipperary and Kilkenny as early as 1270, but it is thought that this is an unrelated Norman name. ... The first recorded spelling of the family name is shown to be that of Gilla Corr, which was dated 1186, Annals of Ulster, during the reign of King Henry 11, 'The Builder of Churches', 1154-1189.
