John Duncanson (minister)

John Duncanson (ca. 1530–1601) was a Scottish minister, one of few Roman Catholic clergymen who willingly converted to the new Protestant doctrines at the Reformation. He was reputed to have lived to be nearly 100 years old, but this is unlikely, as the earliest surviving mention of him was as minister at Stirling in 1560.

He was the King's Minister, tutor and chaplain to King James VI, and Moderator of the General Assembly of the Church of Scotland in 1574 and 1576.

Duncanson married Janet Watson. Their eldest son was James Duncanson (ca. 1564–1624), Minister at Alloa, Clackmannanshire, who married Helen Livingston.
