The Gaelic-Irish Lordship of Molahiffe (Irish: Magh ui Fhlaithimh) was created in the 14th century by Eóghan (Owen) Mór MacCarthy, Lord of Coshmaing, as a grant to his son, Donal.[2] Molahiffe Castle was also the seat of The Paramount Lordship of Cosmaigne (Ard Tiarnas na Coshmaing).[3] The Gaelic title, Lord (Tiarna/Baron) of Molahiffe (in legalese, an incorporeal hereditament), should not be confused with the Baronetcy of Molahiffe, which was an English title held by some of the Browne family (Earls of Kenmare) after they took possession of former MacCarthy lands at the beginning of the seventeenth century. Alternate spellings of Molahiffe include "Mullahiffe," and, "Moylahiffe."
