Crotty

Crotty (and variations O’Crotty, Crotti, Crottee, etc.) are anglicisations of the Irish name O’Crotaigh – ‘Descendant of Crotach’. The name dates from medieval times, to the pre-Norman kingdom of Thomond ('North Munster') where the Dál gCais (in English: ‘Dalcassian’) clan, centred on the regional rulers - the Uí Briain (O'Brien) family - were dominant. The Crottys were one of eight septs of the O’Briens (i.e. descended via the female line - hence the different surnames). They settled in Western Co.Waterford and Eastern Co.Cork.
