The surname Hagarty originated in Ireland, with its earliest known recordings dating back to the 16th century. It is an anglicized version of the Irish Gaelic name "Ó hAgartaigh," which translates to "descendant of Aghartach." Aghartach is derived from the Irish word "aghar," meaning "valiant" or "warlike."
The name Hagarty is predominantly found in Counties Mayo and Galway, located in the Connacht province of western Ireland. It is believed that the Hagarty clan descended from the Ó Madagáin (O'Madden) family, a prominent Gaelic-Irish dynasty that ruled over the territory of Uí Máine in County Galway during the Middle Ages.
One of the earliest recorded references to the Hagarty name can be found in the Irish Annals, which mention a notable individual named Aghartach Ó Madagáin in the year 1361. This individual was a member of the ruling O'Madden clan and played a significant role in the local politics of the time.
In the 17th century, during the Cromwellian conquest of Ireland, many Hagarty families were forced to relocate from their ancestral lands in Connacht to other parts of Ireland or abroad. This dispersal contributed to the spread of the name across various regions.
Notable individuals with the surname Hagarty throughout history include:
1. Francis Hagarty (1799-1879), an Irish lawyer and judge who served as the Lord Chief Baron of the Exchequer in Ireland.
2. John Hagarty (1788-1853), an Irish lawyer and politician who served as the Solicitor-General for Ireland.
3. Patrick Hagarty (1856-1922), an Irish Catholic priest and author who wrote extensively on Irish history and culture.
4. John Hagarty (1792-1870), an Irish painter and portrait artist who gained recognition for his works depicting Irish rural life.
5. Michael Hagarty (1877-1941), an Irish-American labor leader and politician who served as the President of the United Hatters, Cap and Millinery Workers International Union.
While the Hagarty surname has undergone various spelling variations over time, such as Hagerty, Hagherty, and Haggerty, its origins can be traced back to the historic Gaelic-Irish territory of Uí Máine, where the name has its deepest roots.
