This paper, published over two journal issues, concerns the Carew family of Co. Cork. It is a synopsis of MacCotter¿s masters thesis (UCC, 1994). The Cork branch of this Geraldine family were heirs to Robert fitz Stephen¿s moiety of the lordship of Cork by descent from their ancestor, Raymond le Gros, and which they retained until 1331. This lordship included lands in counties Cork, Kerry and Limerick. These Carews, of Castlecorth (Ballynacurra, Co. Cork), were one of the major magnate families of the period and, in addition to their lands in the kingdom of Cork, also held lands in Waterford, Carlow, Kilkenny, and Mayo. In addition to these lands, this study also explores the three principal manors of the Carews in Cork: Castlecorth, Dunmakothmund (Benduff near Rosscarbery) and Dunnamark (near Bantry). The second part of this article concerns the history of a descendant line, that of the Carews of Garryvoe, Co. Cork.
