Don Rosa's Duck family tree also included the father of Donald's nephews, but his name and face were obscured by a passing bird, a joke about the fact of the kids' father never appearing in the stories. A convention poster Rosa made of the tree has Huey, Dewey and Louie's father's face shown, but the name given (and the last names for Donald's nephews) is the one of whoever is given the poster. A popular misconception is that he is in fact named "Jamie Hawkins", because a scan of this poster shown on the internet had the poster owner's name written under the portrait of Huey, Dewey and Louie's father.
- In the Disney comic parody Return to Duckburg Place, Daffy Duck was said to the nephews' father.
- In the 1999 Duck family tree Der Stammbaum Der Ducks, solely based upon the German translations of Barks' comics, the father of the nephews appeared to be Donald's brother rather than his brother-in-law.
