This version of the Duck Family Tree was an illustration for a 1981 Finnish calendar that was a subscriber gift. Few characters are depicted on it, and the genealogy is mostly based on Vic Lockman's The Castle Heir. It includes the idea that Scrooge McDuck and Grandma Duck are brother and sister, and in this version, they also had two brothers, one of whom was the father of Donald and the other the father of Fethry.
