Malise Sperra appears to have endeavoured to establish himself in Shetland[94] in opposition to Earl Henry. He had seized, it is not stated upon what grounds, the possessions in Shetland which had belonged to Herdis Thorvaldsdatter, and of which Jón Hafthorson and Sigurd Hafthorson were the lawful heirs. It seems as if a court had been about to be held by the earl to settle the legal rights of the parties concerned. The court would be held at the old Thingstead, near Scalloway, but a conflict took place, the dispute was terminated by the strong hand, and Malise Sperra was slain.[95] As a number of his men were slain with him, it seems probable that he had been the aggressor. As both he and the earl are among those who were present at the assembly of nobles at Helsingborg, on the accession of King Eirik of Pomern in September 1389, and the Iceland Annals place the death of Malise Sperra in this same year, it is probable that the earl landed in Shetland on his way home from Norway for the express purpose of seeing justice done in the cause of the heirs of Thordis. In 1391, by a deed executed at Kirkwall (and subsequently confirmed by King Robert III.), he dispones the lands of Newburgh and Auchdale in Aberdeenshire,[96] to his brother David for his services rendered, and in exchange for any rights he may have to lands in Orkney and Shetland, derived from his mother Isabella St. Clair. In 1396 a deed was executed at Roslin by John de Drummond of Cargyll, and Elizabeth, his wife, in favour of Henry, Earl of Orkney, Lord Roslyn, “patri nostro,” by which they renounce in favour of the earl’s male issue, and for them and their heirs, all claims to the earl’s lands “infra regnum Norvagie.”[97] The Diploma states that after the death of the first Henry St. Clair, his mother, the daughter of Malise,[98] came to Orkney, and, outliving all her sisters and all their sons and daughters, became the only heiress of the earldom. It is added that of this thing there were faithful witnesses still living who had seen and spoken with the mother of Henry the first.
