History of the O'Toole name
O'Toole derives from O Tuathail, 'descendant of Tuathal', a personal name meaning 'ruler of the people', from tuath, people or tribe. The O'Tooles were kings of Leinster before being pushed by the Anglo-Norman invasion from their original lands near Naas into the more defensible mountains of County Wicklow, which became their lasting stronghold, alongside the O'Byrnes, for the remainder of the medieval period. From this Wicklow base they mounted repeated resistance against the expanding Dublin Pale for centuries. The name remains most strongly associated with Wicklow and south County Dublin today.
St Laurence O'Toole, Archbishop of Dublin in the twelfth century and the city's patron saint, came from this same royal Leinster family and is the best-known bearer of the name in Irish history.
