Cosgrave: Where does the name Cosgrave come from?

The surname Cosgrave derives from the Irish name Ó Coscraigh, meaning "descendant of Coscrach." Coscrach is a personal name meaning "victorious or triumphant." The origin is primarily associated with two distinct families in Ireland, one located in Leinster and the other in Munster.

Today, the last name Cosgrave is most prevalent in the United States, followed by England and Australia, yet the highest density is in Ireland. Its prevalence in other English-speaking countries demonstrates the diaspora of the Irish due to historical migrations. However, its largest concentration remains in the East Leinster Counties of Kildare and Wicklow in Ireland. In these regions, the Cosgrave family held a family seat from ancient times, and they have a long and distinguished history, which includes several notable personalities such as William Thomas Cosgrave, the first President of the Executive Council of the Irish Free State.
