Huey, Dewey, and Louie Duck are Donald's three nephews and identical triplet sons of Della Duck and an unnamed father.
Beagle Boys
In all comics, the individual Beagle Boys are referred to by their prison numbers as per Barks's convention. In addition to Barks's and Rosa's claim that the Beagle Boys don't know their names, the Beagle Boys-centric comic "Being Donald Duck" (2003) by Olaf Moriarty Solstrand adds that the Beagle Boys don't know their mother's name either, only her number. The Beagle Boys' prison numbers are indicated on the tags seen on the chests of their distinctive orange or red turtleneck sweaters. The original depictions by Barks in American comics most often showed the Beagle Boys with orange sweaters. European comics recolored these same Barks drawings to show Beagle Boys in red sweaters. Subsequent European comic depictions of the Beagle Boys by artists other than Barks also showed them in red sweaters, as did the "DuckTales" cartoons.
In later years, especially in Europe, they appear in the comics as a trio, alongside cousins and other relatives of various talents as spin-off characters. Most notably are the Beagle Brats, the Beagle Boys' three preteen nephews created by Tony Strobl and Steve Steere in "That Motherly Feeling" ("Walt Disney's Comics and Stories" #299, 1965). They mirror criminal versions of Huey, Dewey and Louie and have the prison numbers 1, 2 and 3. Another prominent relative is Intellectual-176 (or I-176), the Beagle Boys' cousin who acts as the brains of the Beagle clan. He wears a mortar-board cap and glasses over his black bandit mask. I-176 was created by Pete Alvarado and first appeared in "The Crown Jewel Job" ("The Beagle Boys" #7, 1967).
