treasure, eventually trapping himself inside the castle walls with it. Quackly and his treasure became a McDuck legend, and it is believed that his ghost continues to protect the treasure and the castle. In 1877, Quackly's ghost saves a young Scrooge McDuck from the Whiskervilles of Dismal Downs. Without revealing his true identity, he suggests to Scrooge that he travel to America and work for his Uncle Pothole, thus serving as the catalyst for all of Scrooge's adventures. In 1885, Quackly again tries to save Scrooge, but his action unintentionally brings about Scrooge's temporary death. In heaven, Quackly is reprimanded by his relatives for interfering in earthly events. Quackly McDuck is first mentioned in The Old Castle's Secret (1948) by Carl Barks, and first appears in The Last of the Clan McDuck (1994) by Don Rosa. 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 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's, disappearance. Stuft McDuck Sir Stuft McDuck (1110-1175) was a successful chief of Clan McDuck who oversaw a period of prosperity. Roast McDuck Sir Roast McDuck (1159-1205) succeeded his father, Stuft McDuck, as clan chief, while Clan McDuck was one of the richest clans in Scotland. However, in 1189, Roast offered much of the clan's wealth to the king of Scotland, William the Lion, after William asked for his help in paying tribute to Richard I of England. This act of patriotic generosity led to
