Harold Maddadson's children by his first wife, namely Henry of Ross, Hakon, Helena and Margaret would, in 1165, all be born, but would be well under twenty-one, while of his second family, if Gormflaith was born by 1135, which is unlikely, his eldest son, Thorfinn could have been born, and some of the others. Thorfinn is mentioned by name in a grant[33] of a silver mark per annum to the Church of Scone issuing out of Harold's lands, of which the date is after 1166, but no one can say how much before the 30th December 1184, the date of the death of one of its witnesses, Andrew, Bishop of Caithness. If the union with Gormflaith took place after 1174, no child of that union would exist until 1175. That this is in fact true is rendered more probable because their union is not mentioned in the _Flatey Book_ until after the death of Sweyn in 1171. But the passage is of doubtful authenticity, (see Rolls Edition p. 224), and inconclusive even if genuine. From the various allusions to Harold's union with Gormflaith, it would seem that Harold lived with her before he married her for many years, but married her legally after his first wife Afreka's death after 1198 when William the Lion stipulated that he should take Afreka back, and the subsequent legal marriage might in those days, under the Canon and Roman law, suffice to make Gormflaith's children, though born in adultery, legitimate and capable of succeeding to the earldom (see Dalrymple's Collections, p. 221). In 1165 Sweyn Asleifarson, the great Viking, would be cruising on the northern and western coasts with Harold's son, Hakon, on board, until their deaths in Dublin in 1171. As for those in authority, Harold Maddadson would have as contemporaries, Freskyn of Duffus till his death between 1166 and 1171, and his son William till his death near the end of the 12th century, when Hugo, son of William, would succeed to the Morayshire estates, though probably he had previously obtained a grant of the land then known as Sudrland or Sutherland, which is defined above. Hugo probably received this grant after William the Lion's first conquest of Sutherland and Caithness in 1196, shortly before the time when, as we shall see, Harald Ungi obtained in right of his mother a grant of half Orkney from the Norse king, and another from the king of Scotland of half Caithness, and probably a confirmation of his title to the Moddan lands in Strathnaver and in Halkirk and Latheron, to which he was heir in right of his father and grandmother Audhild of the Moddan line. But this half of Caithness would be conferred on Harald Ungi subject to the prior grant of Sudrland to Hugo Freskyn. For Harold Maddadson must, in the opinion of so eminent an authority as Lord Hailes, have been forfeited in 1196, if not earlier, for both he and his son Thorfinn were then in open rebellion against the Scottish Crown.[34]
