Meaning & History
O'Toole, along with Toole, comes from the Irish O Tuathail. This derives from the personal name Tuathal, meaning "ruler of the people", used by many Irish kings and heroes and accordingly incorporated into a surname in a number of distinct areas, among them south Ulster, Mayo and Kildare.
