Treacy surname: questions
What does the surname Treacy mean?
Woulfe gives Treacy as a form of Ó Treasaigh, 'descendant of Treasach', glossing Treasach as 'fighter'.[1]
Are Treacy, Tracy and Tracey the same name?
Woulfe lists all three as anglicised forms of Ó Treasaigh, and Matheson counted them together in 1890: Treacy 37, Tracey 31 and Tracy 16 births.[1][2]
Where in Ireland is the Treacy name from?
Woulfe names a Leinster family, lords of Ui Bairrche (barony of Slievemargy, in Leix), and a Connacht family in south-east Galway; he says the name is now common in many parts of Ireland. In 1890 Treacy was found chiefly in Tipperary and Galway, Tracey and Tracy in Dublin.[1][2]
Were there Tracys in England?
Yes. The Dictionary of National Biography says William de Tracy (d. 1173), one of the murderers of Thomas Becket, belonged to a family which in the twelfth century held considerable property in Devonshire and Gloucestershire.[3]
