Garrity ~ Ó Garraidh

The Story of the Garrity Name

Garrity is an anglicized form of the Irish Ó Garraidh, meaning “descendant of Garraidh.” The personal name Garraidh is an Irish form of the Germanic name Gerald, introduced to Ireland through the Anglo-Norman world. The surname therefore reflects the blending of Gaelic and Norman naming traditions that became woven into Irish family history.

The Ó Garraidh family was particularly associated with County Mayo, where the name became established among the Gaelic families of Connacht. The surname was also found in neighboring parts of western Ireland, including Galway and Roscommon, as branches of families moved throughout the province.

The personal name Garraidh became part of the Irish naming tradition during the medieval period, when names of Norman and continental European origin were adopted and Gaelicized. Gerald itself comes from Germanic elements associated with “spear” and “rule,” giving the underlying name a traditional connection with strength, leadership, and authority.

As English influence expanded, Ó Garraidh was increasingly anglicized, eventually producing forms such as Garrity, Garritty, and Geraghty. Like many Irish surnames, its spelling varied considerably in historical records as Gaelic names were written according to English pronunciation. Families bearing the name later spread beyond their western homeland and joined the wider Irish diaspora.

Behind the familiar name Garrity lies the story of a surname shaped by the meeting of Gaelic, Norman, and English traditions in medieval Ireland. From the communities of Mayo and Connacht to Irish families around the world, Garrity carries forward the memory of Ó Garraidh and the enduring heritage of Ireland's western Gaelic families.
