Treacy

Treacy is an Irish surname originating as a variant of Tracey (2), itself an Anglicized form of the Gaelic Ó Treasaigh. This patronymic name means "descendant of Treasach," and the root name Treasach derives from Old Irish Tressach, signifying "warlike, fierce" or more simply "fighter."

Etymology

The surname Treacy follows the common Irish pattern of adopting an Anglo spelling of an original Gaelic name. The root treas conveys ideas of battle and strength, making the name one of many Irish surnames that denote martial prowess, echoing the warrior culture of early medieval Ireland.

Notable Bearers

In athletics, John Treacy (born 1957) is an Irish Olympic long-distance runner, winner of silver medals in cross country and a two-time Olympian in the marathon.
