McDuck (1437-1509) was the treasurer of the Knights Templar and hid their treasure beneath McDuck Castle. He is mentioned in The Old Castle's Other Secret or A Letter from Home (2004) by Don Rosa. In the 2017 DuckTales series episode, "The Secret(s) of Castle McDuck", Scrooge McDuck states Simon was the "accountant" to the Knights Templar who had stolen and hidden their treasure somewhere underneath Castle McDuck, and he had returned to his father Fergus to reluctantly ask for his help in finding it since he knows where it is. His ghost appears later in the episode to stop a ghost hound from attacking Scrooge's grandnephews, Huey, Dewey, and Louie. Early modern McDucks Malcolm McDuck Malcolm "Matey" McDuck (1530-1564?) was a McDuck relative who settled in England and is suggested to be a previous incarnation of Scrooge McDuck. Malcolm served in the English Navy, and in 1563 he became first mate of the frigate HMS Falcon Rover, serving under Captain Loyal Hawk. The Falcon Rover raided Spanish targets in the Caribbean Sea between 1563 and 1564. Also serving on the Falcon Rover was the boatswain, Pintail Duck, whose descendant, Quackmore Duck, would marry Malcolm's descendant, Hortense McDuck.

Malcolm first appears in "Back to Long Ago!" (1956) by Carl Barks. He is mentioned on Webby Vanderquack's family chart in the 2017 DuckTales series.
