Surname Uí Treasaigh - Meaning and Origin

all surnames with 'U'

Uí Treasaigh: What does the surname Uí Treasaigh mean?

The surname Uí Treasaigh (also known as O’Treacy, O’Tracy, Tracy, Treacey, and Tracey) is an old Irish surname of Gaelic origin. It is derived from the ancient Irish chieftains, known as the Uí Treasaigh, or Uí Treasaighean, who were a dynasty of the Dál gCais people in the Province of Munster. The surname refers specifically to one of the seven distinct septs of the same name, which is related to the ancient Celtic people of the same name.

The name Uí Treasaigh is thought to have been given to the septs because they derived their name and their lands in ancient Ireland from “treasach”, a Gaelic word meaning “warrior”. This is in reference to the long history of the Uí Treasaigh of waging war and protecting the people of their land. The name is also believed to be a derivative of “treasach”, a Gaelic word which means “colt”, and is thought to be a reference to their ancient Celtic horse breeding practices.

The Uí Treasaigh is said to have originated from the County Clare in the late 12th century. Having settled in the locale, they quickly grew in power and strength, ruling the area for centuries. Over the years, the Uí Treasaigh expanded their influence and eventually established domains in what are now the counties of Tipperary, Kerry, and Galway.

Today, the name Uí Treasaigh continues to live on in many parts of Ireland, and amongst the diaspora of Irish living abroad. It is a proud reminder of the legacy of a great ruling family and of the proud ancient heritage of people of Irish descent.
