Seaán mac Oliver Bourke
Seaán mac Oliver Bourke, 17th Lord of Mac William Íochtar.
Burke was the son of Oliver of Tirawley and a great-grandson of Ricard Ó Cuairsge Bourke. He developed his power base using gallowglass mercenaries, and by 1570 was regarded as the next Mac William Íochtar. He was created Baron Ardenerie in May 1580.
Despite the contemporaneous culture of those of his class, he had little love for war and seemed concerned for the well-being of his people. Upon being reproached by an old woman for burdening his people with the maintenance of his Scottish troops, he lamented that without them, they would be at the mercy of their enemies who would be just as burdensome.
Bourke is rightly famous as the patron of The Book of the Burkes. He spoke Irish and Latin, but not English.
He died on 24 November 1580 and was succeeded by his son William.
