Note (return) — Chapter III

In the reign of Constantine II, Kenneth's son and next successor but one, further incursions by the Northmen took place under King Olaf the White of Dublin in 867 and 871; while in 875 his son Thorstein the Red, by Aud "the deeply-wealthy" or "deeply-wise," landed on the north coast, and, we are told, seized "Caithness and Sutherland and Moray and more than half Scotland,"4 being killed, however, by treachery within the year. His mother Aud thereupon built a ship in Caithness, and sailed for the Faroes and Iceland with her retinue and possessions, marrying off two grand-daughters on the way, one, called Groa, to Duncan, Maormor of Duncansby in Caithness, the most ancient Pictish chief of whom we hear in that district, and probably ancestor of the Moldan, or Moddan, line in Cat. Two years later, in 877, King Constantine was defeated by a force of Danes at Dollar, and slain by them at Forgan in Fife.5
