Gus Goose

When he was introduced he was said to be Donald Duck's Cousin but Carl Barks never saw it that way. Gus is however related to Donald. In fact Don Rosa shows him on his Duck Family tree as the son of Luke the Goose and Fanny Coot. Fanny is the daughter of Grandma Duck's Brother Casey Coot and that makes Gus Grandma's Grandnephew which makes him a distant cousin of Donald's.
