McCourt
An Irish surname usually understood as a shortened form of Mac an Chomhairce, meaning “son of the defender” or “son of the protector.”
The #7,868 most common surname in the United States (2010 Census) — about 1 in every 73,406 Americans shares it.
Etymology
McCourt is an Anglicized Irish surname, generally linked to Gaelic Mac an Chomhairce, literally “son of the defender” or “son of the protector.” The form reflects the common Irish Mac- prefix (“son of”) plus a personal byname built on a word for help, protection, or guarding. Older sources sometimes give related spellings such as MacCourt, McCord, or McCartney-like simplifications, showing how the name was reshaped in English records.
History
The surname is found in Irish records and later in diaspora communities, especially in North America and Britain, where Anglicized spellings became fixed. Historical surname dictionaries and census listings show McCourt as one of a cluster of similar Irish Mac- names, though the exact Gaelic source was sometimes handled inconsistently by early scholars. Today McCourt is best known internationally through the writer Frank McCourt.
