Luke the Goose

Luke the Goose is the father of Gus Goose.

He was originally supposed to be Gladstone Gander's father, Daphne Duck's husband and Gus's uncle, but Carl Barks later changed his mind about that matter, making Goosetave Gander (who was originally Gladstone's adoptive father after Luke and Daphne "overate at a free-lunch picnic") Gladstone's biological father and Daphne's husband. Luke the Goose disappeared from the tree.

When Don Rosa created his Duck Family Tree, he used Luke Goose (removing the "the" in his name) and made him the husband of Fanny Coot and Gus Goose's father.
