Irish form: Ó Deasmhumhnaigh

Meaning: “of South Munster”

Traditional stronghold: Cork

Pronunciation: DEZ-mund; Irish O Deasmhumhnaigh: oh DYAS-voo-nig

History of the Desmond name

Desmond derives from O Deasmhumhnaigh, meaning 'the south Munster man', from deas, south, and Mumhain, Munster, and it is closely intertwined with the great Anglo-Norman Fitzgerald Earls of Desmond, whose title came from the same territorial name, Deasmhumhain. As a surname in its own right rather than a title, Desmond is associated chiefly with County Cork and County Limerick, the historic heartland of the old Desmond earldom. The Fitzgerald earls became so thoroughly Gaelicised over the medieval centuries that their downfall in the sixteenth-century Desmond Rebellions marked the end of one of Ireland's most powerful lordships, and the place name lived on afterwards as a personal surname.
