Kings of Munster in the context of Ó Caoimh

Ó Drisceóil, O'Driscoll (and its derivative Driscoll) is an Irish surname. It is derived from the Gaelic Ó hEidirsceoil. The O'Driscolls were rulers of the Dáirine sept of the Corcu Loígde until the early modern period; their ancestors were Kings of Munster until the rise of the Eóganachta in the 7th century. At the start of the 13th century, the prominent branches of the family came into existence: Muintear Uí Dhrisceóil Mhóir, Ó Drisceóil Óg, Sliocht Thaidhg and Ó Drisceóil Beara. The Ó prefix was illegal in Ireland during the 17th and 18th centuries. The surname is now most prominent in the Irish counties of Cork and Kerry.

Cathal mac Finguine (died 742) was an Irish King of Munster or Cashel, and effectively High King of Ireland as well. He belonged to the Eóganacht Glendamnach sept of the dominant Eóganachta kin-group whose members dominated Munster from the 7th century to the 10th. His father, uncle, grandfather and great-grandfather had also been kings of Cashel, as were his son and grandson.

Cathal's conflict with the Uí Néill kings, Fergal mac Máele Dúin, Flaithbertach mac Loingsig, and Áed Allán, son of Fergal mac Máele Dúin, is reported at some length in the Irish annals, and again northern and southern versions provide differing accounts. Cathal also appears as a character, not always portrayed sympathetically as in Aislinge Meic Con Glinne where he is possessed by a demon of gluttony, in a number of prose and verse tales in the Middle Irish language.
