Note 70 — CHAPTER THE THIRD. CONSTANTINE THE SECOND—A. D. 900-943.

Olave was Constantine’s son-in-law at the time of the battle of Brunanburgh, but as Sitric died at an early age, and Olave survived his father for nearly sixty years, it is improbable that the connection could have existed till some years after Sitric’s death, when it will explain why Constantine, who at that time was not at variance with Athelstan, and who had supported the Northumbrian Saxons against their mutual enemies the Hy Ivar, became an object of suspicion to the English king when it appeared to be his aim to favour the establishment of his son-in-law in the Danish province, as he had already secured his brother upon the throne of Strath Clyde.
