Abstract of Title from the Earl of Bantry to Daniel O’Sullivan, Rents of Brennymore, Kealkil, West Cork, 1787 probably family who bought Carriganass Castle from Mellifonts c 1820 names mentioned James Morgan Cooke, Thomas Stephen Coppinger, Denny Lane, John Barrett O’Sullivan, Norcott Parker, Robert Neville Reaves, and de facto control of Confiscated Lands by O’Sullivan Septs in Bantry/Kenmare Estates in South Kerry, Beara and Bantry areas.
The Estate records show a remarkable continuity of O’Sullivans having substantial leases. In the 18th and 19th century branches of the various families appear to have retained de facto control. These families intermarried with similar Catholic families such as the O’Connell of Derrynane, Co. Kerry, the O’Learys, the McCarthys, the O’Donovans and also into the Protestant Gentry families being similar on the social scale. As the Penal Laws were relaxed in the later 18th century they began to serve in the British Military Service and also enter the Legal and other Professional areas.
