Kingdom of Desmond
The area of the original Lordship of Molahiffe was within the territory of the Paramount Lordship of Cosmaigne/"Coshmaing" (specifically, the area known as East Cosmaigne), and descended from the original appanage of "Sliocht Eóghan na Coshmaing". Although, in the present day, no territory attaches to the title of Lord (Baron) of Molahiffe, it was, in the 14th-century, located in the Kingdom of Desmond, in modern-day County Kerry, Barony of Magunihy. The northern boundary of the Lordship of Molahiffe (as well as the Kingdom of Desmond, Coshmaing, and the Barony of Magunihy) was the River Maine, which flows into Dingle Bay at Castlemaine Harbor. However, as Butler notes, "The two projections of the barony to the north of the Maine are in Molahiffe..." (see map). The area of Molahiffe projecting to the north of the River Maine ("Maing") extended to the ridgeline of the Slieve Mish mountain range, which partly bisects the Dingle Peninsula.
