It is generally thought that the surname Dunlea is derived from the Irish Ó Dubhalla sept of Muskerry, Cork. It has also been suggested that Dunlea comes from a branch of the famous MacDuinnsleibhe sept. However, since the MacDuinnsleibhe sept was located in Ulster and bearers of the name Dunlea were for the most part located in the south western counties of Munster, this connection seems rather unlikely.
