'Hinguar and Hubba' - Abbo describes Hinguar (ON Ívarr) as one of the devil's right-hand men (unum ex suis membris). Irish annalists call him 'King of all the Norsemen of all Ireland and Britain'. Later Norse sources identify him as a son of Ragnar Lothbrok. Hubba (ON Ubbi) is also described as a son of Ragnar in the Annals of St Neots (c. 1125).
