Whitewater Duck

Whitewater Duck was created by Carl Barks and used by him only in the story "Log Jockey", published in Walt Disney's Comics and Stories #267 on December, 1962. According to that story, he is a distant cousin of both Donald Duck and Huey, Dewey, and Louie, and works as a lumberjack in the woods. When he gets hurt on a foot shortly before a competition with rival lumberjack Pete, he teaches Donald how to be a lumberjack to compete with Pete.

On Don Rosa's Duck Family Tree, Whitewater's real name is stated to be Abner Duck, with "Whitewater" only being a nickname. He is also shown to be a son of Eider Duck and Lulubelle Loon and the brother of Fethry Duck, making him Donald's first cousin.

In his second appearance in a story, "Smarter Than The Toughies" (published in the USA in Uncle Scrooge #349) by Lars Jensen and Daniel Branca, Whitewater is instead shown to be the nephew of Scrooge McDuck's cousin Douglas, making him Donald's second cousin.

In his third appearance in a comic story, "Too Many Donalds" (as of July 2013 unpublished in the USA) by Lars Jensen and Carlos Mota, Whitewater was seen to be in a relationship with Donna Duck. In this story, Donald introduces Whitewater to Daisy as his distant cousin.
