O'Rourke, Brian-na-Murtha (died 1591)

Irish chieftain, a leading opponent of English rule in Ireland in the late 16th century. Large areas of Galway, Sligo, and the west of Ulster were under his control, where he sheltered shipwrecked sailors from the Spanish Armada. He went to Scotland to seek support from James VI, but was detained and handed over to the English, who tried and executed him at Tyburn, London.
