O'Dea History, Family Crest & Coats of Arms
- Origins Available:
All Irish surnames have a unique and often romantic meaning. The name O'Dea originally appeared in Gaelic as O Deaghaidh or O Diaghaidh.
Early Origins of the O'Dea family
The surname O'Dea was first found in County Clare (Irish: An Clár) located on the west coast of Ireland in the province of Munster, where O'Dea was chief of Dysart-O'Dea, now the parish of Dysart, barony of Inchiquin, one of the original chiefs and clans of ancient Thomond. Today Dysert O'Dea Castle still stands near Corofin, County Clare with its Romanesque Doorway and High Cross and was the site of the Battle of Dysert O'Dea in 1318. It was here that the Irish chieftain Conor O'Dea, chief of the Cineal Fearmaic and ally of Murtough O'Brien, stood his ground only to be defeated by the invading forces from Scotland.
