From de Burgh to de Búrca
Members of the Anglo-Norman de Burgh family became established in Ireland during the late twelfth and early thirteenth centuries. In Ireland the name took on new forms, including de Búrca, Burke and Bourke. This transformation reflects centuries of settlement, intermarriage, Irish-language use and regional history.
Why Connacht matters
De Burgh power became especially important in Connacht. The family divided into two great branches: Mac William Uachtar in Galway and Mac William Íochtar in Mayo. Their territories, alliances and castles shaped the political landscape of western Ireland for generations.
Those Connacht branches are central to the surname story, but Burke and Bourke families also spread into other counties. Local records reveal how particular households fit into the wider history.
