Crotty


Crotty are anglicisations of the Irish name Ó Crotaigh – ‘Descendant of Crotach’.
The name dates from medieval times, to the pre-Norman kingdom of Thomond where the Dál gCais clan, centred on the regional rulers - the Uí Briain family - were dominant. The Crottys were one of eight septs of the O’Briens. They settled in Western Co.Waterford and Eastern Co.Cork.
In common with the O’Briens - and the millions of descendants of the other seven septs - the Crotty sept's likely ultimate common ancestor is Brian Bóruma mac Cennétig c.941 – 1014, and therefore possibly as far back as Cormac Cas in the 3rd Century.
The name originates in present-day County Clare, and is still most common in the general area of the former kingdom of Thomond.
Spelling variations include Crotty, O'Crotty, Crotti, Crothon, Crotton, Crotone, Crottee, Crottey, O'Crottey, O'Crottee, O'Crottie, Croddy, and Cratty. Other non-anglicised versions in use include Crothaigh, Chrothaigh etc.
The other seven related septs of the O'Briens are the families: Bernard, Consadine, Lysaght, MacMahon, O'Mahoney, Padden/MacFadden and Plunkett.
