Della Duck, occasionally referred to as Dumbella Duck or Thelma Duck, is Donald Duck's sister and the daughter of Hortense McDuck and Quackmore Duck. She is the mother of Huey, Dewey, and Louie, Donald's triplet nephews.
Donald's sister was first mentioned in the cartoon short Donald's Nephews (1938), in which she sent her sons Huey, Dewey, and Louie to visit Donald. A comic adaptation of the short was written into the Donald Duck newspaper comic strip of 1937, in which it was told that the nephews' father was in the hospital after a giant firecracker had exploded under his chair. In this comic, Della was still said to be Donald's cousin, rather than his sister.
In the newspaper comic strip of November 21, 1937, Donald, who has grown increasingly tired of his nephews, receives a telegram from Della in which she says that she wants Huey, Dewey and Louie to come back home, which they do, much to Donald's pleasure. However, the trio returned to appear in the comic strip not long after their departure. As of the 1942 cartoon The New Spirit, they were listed as being adopted by Donald.The nephews briefly mentioned both of their parents while saying their prayers in the Donald Duck newspaper comic strip Amen!, written by Bob Karp and drawn by Al Taliaferro.
The nephews' mother made her first visual appearance in Mark Worden's illustrated version of Carl Barks' Duck family tree, by the name Thelma Duck, which was given to her by Barks. However, in Don Rosa's Duck Family Tree, first published in 1993, she was given the first name Della again. Della later appeared as a child alongside her brother and her parents in Rosa's The Empire-Builder from Calisota, chapter 11 of the Eiser Award-winning comic book series The Life and Times of Scrooge McDuck. According to this comic, Della and Donald are twins.
Della was one of the first female pilots, and eventually became an astronaut, leaving her children with her brother just before she left for a space trip, as shown in the Dutch Disney comic 80 is prachtig. This comic was made in honor of Donald Duck's 80th anniversary in 2014, and was published in a special issue of the Dutch Donald Duck magazine.
- "Della" was also the first name of Al Taliaferro's aunt.
- In an early French translation of the comic adaptation of Donald's Nephews, Huey, Dewey and Louie were sent to Donald by Clarabelle Cow instead of his sister.
- Della made a very obscure cameo appearance in Don Rosa's The Sign of the Triple Distelfink. During a flashback of Gladstone, she can be seen at young Gladstone's birthday party.
- Della's introduction was the first time a Sensational Six member was explicitly said to have a sibling (Morty and Ferdie's mother was already introduced in 1932, but she was said to be Mickey's sister years after her first appearance).
- In The Duck Who Never Was by Don Rosa, it's shown that if Donald wasn't born, Della would have left her children with her cousin Gladstone.
