Note 107 — Chapter III · THE GROWTH OF THE SEAPORT TOWNS.
Reading edition
Three Fragments of Annals (A.D. 860) record that “two fleets of the Norsemen came into the land of Cearbhall, son of Dunlaing (King of Ossory) to plunder it.” These fleets probably sailed up the Barrow from Waterford harbour. The same annals also mention (p. 129) a Norse chieftain called Rodolbh, who may have been connected with the colony at Waterford. See also Annals of the Four Masters, A.D. 888 [891].
