Early Origins of the Denny family

The surname Denny was first found in Cork (Irish: Corcaigh) the ancient Kingdom of Deis Muin (Desmond), located on the southwest coast of Ireland in the province of Munster, and Kerry where they held a family seat. The first recorded instance of the name is of Donall O'Denaghie of Cloghlea, County Cork, a vestarius (keeper of the vestry) in 1585. According to Irish lore, bearers of this name were traditionally descended from Maoin, brother of Muircaertach Mor MacEarca, King of Ireland. Many Irish sept (clann) names were intermixed and family groupings became almost indistinguishable. Bearers of this name often changed Danagher to Dennehy, and Dennehy to Denny.
