McDuck. The family tree accompanying it was first published in Norway on July 3, 1993. In the process of working on Scrooge's biography, Rosa studied Barks' old stories in detail. Rosa made note of as many clues as he could of Scrooge's past given by Barks – which Rosa dubbed "Barksian facts" – and used them to write new stories. Despite the ambitious nature of the project, Rosa himself stressed in the introduction to the book "...this version of Scrooge's life is not the 'official' version – there's no particular reason why I (or anyone else) should expect other Duck writers to adhere to my vision of Scrooge's history. As carefully and authentically as I sought to construct it, it was never intended to be anything but my personal telling of the life of Scrooge McDuck." Modern family tree by Carl Barks The family tree below shows the McDuck portion of Donald's family tree according to Carl Barks.

According to Barks, Matilda McDuck is married to Goosetail Gander, and the couple adopts Donald's cousin Gladstone. The character Old "Scotty" McDuck does not appear in any stories, but eventually became Fergus McDuck in Don Rosa's stories.

The nearest village is the fictional MacDuich. The castle usually appears in good condition considering its great age. However, in the Barks story "Hound of the Whiskervilles" (1960) the castle is in ruins. The comics continuity does not establish when McDuck Castle was built, but it first appears (on the fictional timeline) in 946 when the Saxons laid siege to it. For many centuries the castle served as the home of the clan chief. In 1675, the McDucks were run out of the castle due to the depredations of a "monstrous devil dog" in Dismal Downs, later discovered to be a plot by the rival Clan Whiskerville. At this time, many of the McDucks moved to the village of MacDuich and to Glasgow. Even after their departure, the clan still owned the
