Duck family (Disney)
In the comic story "The Family Tree Spree" (1962), Donald discovers that he has only two notable ancestors. One is Columbust Duck, who tried to prove the Flat Earth model. The other is Deadeye Duck, a stagecoach robber. If Columbust lived at the same time as Christopher Columbus, he would be Donald's oldest known relative on his father's side. On his mother's side, Donald's earliest known relative lived in the second millennium BC.
