General Notes

Alias:<ALIA> Cnut or Knut den store /Canute/,den Mektige
According to ENCYCLOPAEDIA BRITANNICA
(http://www.britannica.com/bcom/eb/article/3/0,5716,20393+1,00.html): 
"Neither the place nor date of Canute's birth is known.  As a youth he
accompanied his father, Sweyn I Forkbeard, king of Denmark, on his
invasion of England in 1013.  Canute was left in charge of the fleet at
Gainsborough, Lincolnshire, and it was probably then that he met
Aelfgifu, daughter of an ealdorman (chief officer) of Northumbria who had
been murdered with King Aethelred II's connivance in 1006; she bore him
two sons, Sweyn and Harold...Canute proved an effective ruler who brought
internal peace and prosperity to the land.  He became a strong supporter
and a generous donor to the church, and his journey to Rome was inspired
by religious as well as diplomatic motives...Neither Canute's
illegitimate son Harold, who ruled England until 1040, nor his legitimate
son Hardecanute, who succeeded to Denmark in 1035 and to England in 1040,
inherited his qualities.  The English reverted to their old royal line in
1042, and Denmark passed to Sweyn II, son of Earl Ulf (Ulf Jarl, the
husband of his sister Estrid) and Estrid."
According to Tom Bjornstad, Norwegian genealogist
(http://home.ringnett.no/bjornstad/royals/Norway.html):
"Canut the Great was technically the king in Norway from 1028, but he
left Hakon, Earl of Lade, in charge after the defeat of Olaf II the same
year.  Hakon died though, so Canute overtook himself for a year, before
putting Swein Alfivason in as a sub-king in 1030.  Canute was king of
England, Denmark and Norway for a time."
