Recognised under patronage of the President of Ireland by Clans of Ireland

Anglicised across generations as Commane, Coman, Comyn, Cummins, Hurley, and related forms —

Clan Ó Comáin is an ancient royal house in the Gaelic nobility of Ireland, one of the oldest documented. Their ancestral capital, Cahercommaun in County Clare, a triple ring stone fort regarded as one of the most important ancient sites in Munster, was a ceremonial inauguration site of the Chiefdom of Tulach Commáin. Their lineage extends through the kings of Déisi Munster, the royal dynasty of Uí Maine in Connacht, and the spiritual legacy of Saint Commán — founder of Roscommon and the ancient church at Kinvara. A direct male line confirmed by DNA stretches unbroken in Ireland for over 4,000 years.

The name today extends far beyond Ireland — a Commane Road in Baldwinsville, New York testifies to the family's Famine-era emigration to America, while the name appears in several locations in France, reflecting the Wild Geese exile of Irish Gaelic families after 1691.

Cahercommaun/Cahercommane, The Burren, Co Clare, our ancestral capital

Original Naming of archaeological site Cahercommane: Thomas Johnson Westropp (Irish antiquarian, Trinity College Dublin, documented Clare’s antiquities, authored Archaeology of the Burren 1917, president of the Royal Society of Antiquaries of Ireland), in his early 20th-century surveys, documented the site as both Cahircommane and Cahercommaun, noting a 1585 deed from Elizabeth I that refers to the townland name Tullycommon as Tullagh Coman, suggesting the personal name Commán as its root.

Hugh O’Neill Hencken (American archaeologist, Harvard University Ph.D, led the Third Harvard Archaeological Expedition 1934 excavating Cahercommaun) in his 1938 excavation report, retained Cahercommaun despite noting its appearance as Cahircommane on the 6-inch Ordnance Survey map, highlighting possible linguistic variations, with both scholars agreeing the name likely reflects a historical figure named Commán tied to the chiefdom in Clare.
