The O'Grady family, also styled O'Grady of Kilballyowen, is one of Ireland's noble families and surviving Chiefs of the Name. Their title is: The O'Grady in English and O Grádhaigh in Gaelic.
They belong to the Dál gCais kindred and are distant cousins to the famous O'Brien dynasty, but have since the Middle Ages been based not in County Clare, from where they originated, but in County Limerick. The (former) seat of the family, Kilballyowen, is near the town of Bruff.
The name Standish was often used by the family; it derives from the marriage in 1633 of Darby O'Grady, The O'Grady, to Faith Standish.
The current Chief of the Name is Henry Thomas Standish O'Grady, The O'Grady, who resides in France.
