Editing Clan McDuck (section)

=== Murdoch McDuck ===
'''Sir Murdoch McDuck''' (?-1066; from earlier Murdoch MacDuich) was a businessman who patented the longbow. Most notably in 1066, when the Normans invaded England, he had the latter sign a contract with him so they would have enough longbows to fight off the invaders. However, they did not have enough arrows as Sir Murdoch charged extra for them. He is also the last of the Dark Ages McDucks and the one who modernized their family name "MacDuich" to the more familiar "McDuck". He only appears in the unfinished sketch-only story "The History of the Clan McDuck" (written and drawn approx. in 1992 by Don Rosa, but not released until December 2011), which was meant to serve as a prologue to "The Last of the Clan McDuck" before it was scrapped.

In the [[DuckTales (2017 TV series)|2017 ''DuckTales'' series]] episode, "The Secret(s) of Castle McDuck!", Downy McDuck relates Murdoch's history (which remains intact) to [[Huey, Dewey, and Louie Duck]], and [[Webby Vanderquack]]. His longbow is later used as a clue that the boys use to uncover the mystery behind their mother, [[Della Duck|Della]]'s, disappearance.
