She replaced Donna Duck, possibly her older sister, as Donald's girlfriend since 1940 though she occasionally dates their common cousin Gladstone Gander. She has Donald's temper but is a bit more sophisticated. One of her brothers is the father of Huey Duck, Dewey Duck and Louie Duck. A sister of hers is the mother of the triplets April, May and June Duck who serve as Huey, Dewey and Louie's female counterparts.
