About Henry Wemyss, Bishop of Galloway
The Bishop of Galloway is first mentioned in the Sederunt of the Court on 21st March 1533. The individual who then filled that see was Henry Wemyss who according to Douglas, was the son of John, fifth son of Sir John Wemyss of Wemyss, by a daughter of Sir John Arnot of Arnot. As he is, however designed in charters, frater regis and frater natural is regis it has been supposed he was a son of Sir John's daughter, by King James IV. He was a prelate of great piety, according to Lesly, who relates a supernatural interposition of heaven in his favour, during a remarkable storm of wind at Edinburgh, in 1524. He died shortly before 3d July 1541, and was succeeded by Andrew Durie, Abbot of Melrose.

Note: The father of the Bishop of Galloway is disputed. In the above passage it is suggested it may be King James IV, and in Memorials of the family of Wemyss of Wemyss, Volume I (page 101) it is suggested to be Sir John Wemyss.
