Sir Simon McDuck (third from left) with several other Clan McDuck ghosts.

Sir Simon McDuck is one of Scrooge McDuck's ancestors, and a member of Clan McDuck.

Sir Simon was an accountant to the Knights Templar. After stealing the Templar's Treasure, he hid it somewhere in Castle McDuck.[1] As mentioned in "The Secret(s) of Castle McDuck!", only the laird of the castle knows where the treasure is hidden.

Sir Simon died in the early 1500s.

Behind the scenes

  • Sir Simon was created by Don Rosa, for his 2004 comic story "A Letter From Home".
