Note 77 — Chapter II · INTERCOURSE BETWEEN THE GAILL AND THE GAEDHIL DURING THE VIKING PERIOD.
Reading edition
According to A. Bugge, Dubhcenn is a translation of the O.N. Svarthöfthi, but Marstrander (op. cit., p. 45) holds that the name was known in Ireland before the Viking age. It may be suggested that it was a nickname given to Ivarr’s son by the Irish. Cf. Olaf Cuaran (Ir. cuaran, a shoe made of skin); Olaf Cenncairech (i.e., “Scabby-head.”)
