The original name of a sept or clan was Carty, supposed to be derived from Cartheigh, which signifies an Inhabitant of the Rock; and Mac, denoting "son of;" was used before the father's Christian name for the purpose of distinction, as, Mac Cormac Carty expressed Carty, son of Cormac; this manner of designation appears discontinued on the introduction of a greater variety of names, and the Mac alone retained by the elder branches.
