Note 538 — Chapter V · THE DANISH CONQUEST OF ENGLAND.[464] 975–1016.
Reading edition
It would, I imagine, be very hard to find out the exact point in Olaf Tryggvesson’s life when, according to his Saga (c. xiii.), he made expeditions in Britain, Ireland, and Scotland, attacking the heathen and keeping peace with the Christians. It would be hardly more difficult to identify the daughter of an Irish King and widow of an English Ealdorman, whom Olaf marries in the next chapter. See above, p. 269.
