I question whether this article is reliable. There is no mention of this person in "Freedom's Sword", Peter Traquair's account of the wars of independence. One work from 1841 does not strike me as a very reliable source. PatGallacher ( talk) 15:26, 20 September 2021 (UTC) reply

Found a few more references confirming existence as Governor of Edinburgh Castle and execution. Coldupnorth ( talk) 20:51, 27 September 2021 (UTC) reply
