Donalbain

Donalbain (sometimes, Donaldbain) is a character in Shakespeare's Macbeth (c.1603-1607). He is the younger son of King Duncan and brother to Malcolm, the heir to the throne. Donalbain flees Scotland after the murder of his father for refuge in Ireland. The character is minor, has few lines, and is sometimes completely cut in modern performance. He is based upon a personage in an account of King Duncan in Holinshed's Chronicles, a history of Britain familiar to Shakespeare. He is based on the historical Donald III of Scotland.
