Haf-rekr

As defined by the Cleasby & Vigfusson Old Norse to English dictionary:

haf-rekr

m. sea-drifted. Heine havreki or Heine the sea-drifted is the name of the hero of a Faroe legend, told by Schlyter in Antiqu. Tidskrift, 1849–1851. The legend makes him the father of the arch-pirate Magnus Heineson, a historical person, whose exploits are told in Debes’ book; this Magnus, we may presume, served as a model to Scott’s Pirate (that Scott knew of Debes is scon from note K to the Pirate). The Faroe legend bears a striking likeness to the Anglo-Norman Haveloc the Dane; both name and story may have a common origin, ‘Haveloc’ being a corrupted French form, with r changed into l for the sake of euphony, haf-rót, n. a violent swell of the sea.
