- Robert Boyd, s. and h. of Sir Thomas B., of Kilmarnock (who d'. 9 July 1 439). He was knighted, and was cr. a Peer of Parl. (LORD BOYD [S.]) by James II at some date between 1451 and 18 July 1454, when he took his seat, as such, in Pari. In 1460 he was one of the Regents [S.] during the King's minority. In 1464 he was one of the commissioners for a truce with Edward IV. Having obtained possession of the person of the young King (for which, as hereafter mentioned, he was eventually condemned for high treason), he was, by Act of Pari. 25 Oct. 1466, made sole Governor of the Realm [S.]; Great Chamberlain [S.] 1467. Early in this year he procured the marriage of his eldest son, Thomas, (cr. Earl of Arran [S.] for that occasion) with Mary, elder sister of the King, which aroused the jealousy of the other nobles. He obtained the cession of Orkney to Scotland, 8 Sep. 1468, from Christian, King of Norway, for whose da., Margaret, he negotiated a marriage with the King. While absent for that purpose he and his said son (the Earl of Arran) and his br.

He was restored to his lands 14 Oct. 1482, but has been generally supposed by Peerage writers not to have been restored to his honours. He had, however, sasine of various lands, on three different dates in Oct. 1482, as James Lord Boyd, and was witness to a charter, Jan. 1483/4, under the same designation.
