THERE is a consensus among historians that the King and the Archbishop of Glasgow did not initially intend to execute John Ogilvie. But the Jesuit priest - Scotland’s only canonised Catholic martyr - could not help himself during questioning, and on March 10, 1615 he was convicted of high treason at the Tolbooth and hanged on the same day at Glasgow Cross. John Ogilvie (1579-1615) claimed to be from a noble family in the North East and to have been raised as a Protestant. He was educated on the continent, converted to Roman Catholicism and was ordained as Jesuit priest at Paris in 1610.
