Which Macbeth character is based on a son from The Danish House of Knytlinga?
House of Knýtlinga The Danish House of Knýtlinga (English: "House of Cnut's Descendants") was a ruling royal house in Middle Age Scandinavia and England. Its most famous king was Cnut the Great, who gave his name to this dynasty. Other notable members were Cnut's father Sweyn Forkbeard, grandfather Harald Bluetooth, and sons Harthacnut, Harold Harefoot, and Svein Knutsson. It has also been called the House of Canute, the House of Denmark, the House of Gorm, or the Jelling Dynasty.
Harthacnut I of Denmark Harthacnut or Cnut I (Danish: Hardeknud ) (born c. 880) was a semi-legendary King of Denmark. "Ragnarssona þáttr" makes Harthacnut son of the semi-mythic viking chieftain Sigurd Snake-in-the-Eye, himself one of the sons of the legendary Ragnar Lodbrok. The saga in turn makes Harthacnut the father of the historical king, Gorm. It has been suggested he is to be identified with the Hardegon of "Northmannia" whose early-10th century conquest of Denmark was related by Adam of Bremen.
