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.
Causantín mac Cináeda Causantín or Constantín mac Cináeda (in Modern Gaelic: "Còiseam mac Choinnich "; died 877) was a king of the Picts. He is often known as Constantine I in reference to his place in modern lists of kings of Scots, but contemporary sources described Causantín only as a Pictish king. A son of Cináed mac Ailpín ("Kenneth MacAlpin"), he succeeded his uncle Domnall mac Ailpín as Pictish king following the latter's death on 13 April 862. It is likely that Causantín 's (Constantine I) reign witnessed increased activity by Vikings, based in Ireland, Northumbria and northern Britain. He died fighting one such invasion.
