Irish Surname - O'Dwyer
The original form of the O'Dwyer name in the Irish language is O'Duibhir (descendant of Duibhir). The meaning of this ancestral name is believed to have meant 'black and dun-coloured', likely referring to a mixture of hair colouring as a personal characteristic. The origins of the name were from the native Gaelic Sept, located in County Tipperary sometime around the tenth century. Their lands were in Kilnamanagh, a mountainous area lying between the town of Thurles and the County of Limerick, and the clan leaders occupied fortified castles in Dundrum, Killinure and Clonyhorpe. The O'Dwyer sept were famed for their steadfast resistance to English attack and many are recorded in connection with this in medieval and early modern times.
Annacarty, County Tipperary, is part of the ancestral home of the O'Dwyers and forms a stage of the Beara-Breifne Greenway which is based on the historic march of O'Sullivan Beara in 1603.
