In 1513, Sir John Moncreiffe, the ninth Laird was killed at the Battle of Flodden, as was his cousin, John, Baron of Easter Moncreiffe. His son was William Moncreiffe the tenth Laird who supported the Douglas Earl of Angus and in 1532 was fined for refusing to attend the Court that condemned Janet Douglas, Lady Glamis to be burned to death as a witch, when her only crime was that of being a Douglas by birth. William Moncreiffe was later captured at the Battle of Solway Moss in 1542 and was imprisoned in the Tower of London. When he was released he embraced the Protestant religion and was one of the barons who subscribed to the Articles in the General Assembly of the Church of Scotland in 1567.
