Question: In addition to Donalbain, who else is a son of King Duncan in Shakespeare's Macbeth?
Sentence (from "King Duncan"): Unlike Holinshed's incompetent King Duncan (who is credited in the narrative with a "feeble and slothful administration"), Shakespeare's King Duncan is crafted as a sensitive, insightful, and generous father-figure whose murder grieves Scotland and is accounted the cause of turmoil in the natural world.
Relevant evidence: No
