Mr McDivot was a male anthropomorphic duck.
At some point, Elizabeth McDivot, daughter of Scrooge McDuck's great-uncle Quagmire McDuck, married this ostensibly wealthy scotsman. Their son, Bogey McDivot, lived in a castle, though it is unclear if he had inherited it from his father.
Behind the scenes
Bogey McDivot's father was spoken of in the 2012 article Bogford McDivot.
