Note 45 — Chapter II · The Kingdom of Scotland—843–900.
Reading edition
Innes App., No. 3. An. Ult. 865, 869, 870, 872. Sim. Dun. de Gestis, 866. Ware. Antiq. Hib., c. 24. Ivar was unquestionably the Inguar of early English history, and perhaps Olave was the Ubba; for in the Langfedgatel quoted by Lappenberg (Eng. under Ang. Sax., vol. i., p. 114, n. 4), Olave is substituted for Uffo, evidently the same name as Ubba. The Chron. 3 ascribes the death of Olave to Constantine, whilst the Landnamaboc says he was killed in Ireland.
