Note 851 — Chapter VI · THE DANISH KINGS IN ENGLAND.[818] 1017–1042.
Reading edition
Sigrid, widow of Eric the Victorious, and mother of Olaf of Sweden, was mother of Cnut by her second marriage with Swegen. J. Magni Hist. Goth. xvii, 17, 18 (Rome, 1554) Olaf died in 1018. Swedish tradition says much of his friendship and hereditary alliance with England, especially with King “Mildredus” or “Eldredus,” of all which I find no trace in English history.
