Note 87 — CHAPTER THE THIRD. CONSTANTINE THE SECOND—A. D. 900-943.

Chron. Sax. 954. Sim. Dun. de Gestis, 1072. Wendover, vol. i., p. 402. Heimskringla, Saga 4, c. 4. The Henricus and Reginaldus of Wendover are probably the Harek and Rognwald of the Saga. Simeon calls Maco or Maccus a son of Olave, but Olave had no son of that name, and Maco was probably “Maccus Archipirata,” or Magnus Haraldson, king of Man and the Islands, who was the head of a different branch of the Hy Ivar. His father, Harald, who was killed in Connaught in 940, was the son of Sitric Mac Ivar, or the elder Sitric, who killed, or was killed by, his brother Godfrey, and was the head of the Norsemen of Limerick. The power of the Limerick Hy Ivar appears to have received a severe shock when Olave Godfreyson, shortly before the battle of Brunanburgh, destroyed all their ships and captured their leader, Olave Cen-Cairedh. A. F. M., 934, 938.
