Matilda McDuck
Matilda McDuck is a fictional character of the Scrooge McDuck universe. She was born in Glasgow, Scotland on 1871 to Fergus McDuck and Downy O'Drake. She is the younger sister of Scrooge McDuck. She would have a younger sister named Hortense McDuck.
In contrast to Scrooge's and Hortense's fiery tempers, she was always amazingly calm. On 1902 Scrooge returned to Scotland and took both of his sisters with him. When he established his homebase in Duckburg, Calisota, United States he left her and their sister to run his empire from 1902 till 1930 . In the meantime he traveled the world expanding his financial empire.
On 1930, a fight with Scrooge ended all relationships between him and his family and she retired. According to Don Rosa, Matilda McDuck went back to tending the McDuck castle in Scotland. She was hired for this job by her nephew Donald Duck in his capacity as Scrooge McDuck's assistant, but without Scrooge's knowledge. She was still alive in the 1950s, as shown in the story "The Old Castle's other secret". This story shows the reconciliation between Matilda and Scrooge. It is suggested that Donald deliberately set them up for a reunion. This is the first time Huey, Dewey and Louie met their great aunt. In that story, Scrooge returns to the McDuck Castle for another treasure and learns from Matilda that his family already knew about the treasure but their father Fergus decided not to tell Scrooge about it. Both Scrooge and Matilda thought that was because of Fergus's disapproval of Scrooge's greedy ways but after finding a letter on the way for the treasure (hence the other title "A Letter from Home") they learn Fergus's real motive was the fact he thought Scrooge would feel better building his own fortune instead of simply inheriting one.
Matilda, while trying to leave the castle, mentions Hortense. However, in the commentary in the American printing of the story, Don Rosa states that he was prevented from using Hortense because he would have had to explain why she had abandoned her family. So Hortense's fate is still left as a mystery.
Matilda is usually drawn with a flower on her hat, which loses a petal in each panel she appears in.
