The Anglo-Saxon Chronicle, a chronological account of the age which is considered a highly reliable source, confirms the story of Ragnar Lothbrok, his deeds, which made a significant impact on the history of 9th century, and his sons carrying on his legacy.
Ragnar Lodbrok (d.840/65) courted the warrior woman Lagertha from afar. Lagertha played hard to get when Ragnar arrived to seek her hand, setting a bear & a great hound that she kept to guard her home upon him; Ragnar killed both. Thus she deemed him worthy of her hand in marriage. According to Saxo Grammaticus, Ragnar had a son with her, Fridleif, as well as 2 daughters.
