Malcolm II. was succeeded by his grandson Duncan,—a daughter’s son by a secular abbot of Dunkeld. Duncan’s right was disputed by his cousin Thurfirm, who was now Earl of Orkney. Duncan went north to check the advance of his kinsman, and was defeated near the Pentland Firth. But an invasion of Danes under King Sweyn on the coast of Fife, and which was probably made in aid of Thurfirm, was defeated by Macbeth, an able general of Duncan’s, and who, it is said, was also a grandson of Malcolm’s, by another daughter. Duncan was _probably_—as in Shakespeare’s great drama—killed by Macbeth. Certainly, to the exclusion of Duncan’s two sons, Malcolm and Donaldbane, Macbeth seized the crown. He reigned seventeen years—1040 to 1057—being contemporary with the Confessor,—a glowing description of whom, posing as a saint with miraculous powers of healing, occurs in Shakespeare’s play. When, on the return of Earl Godwin from exile, there was a general exodus of the Normans, whom Edward had placed in high positions, many of them went to Scotland, and were well received by Macbeth. He appears historically, in spite of our great poet’s portraiture of him, to have been an able monarch; and he might be said to represent Celtic supremacy in Scotland, as against the tendency to subvert it by Anglo-Saxon alliances. Duncan had married the daughter of Siward, Earl of Northumbria, and Macbeth had to resist the attacks of Siward on behalf of his grandson Malcolm. Malcolm spent his boyhood in Cumbria, and his youth at the court of the Confessor. He appealed to Edward for help to gain his father’s throne, and by an English army under Siward, and Macduff, the powerful Thane of Fife, and Tostig, the son of Earl Godwin, Macbeth was overthrown and slain. Malcolm III., named Canmore—“big-head”—reigned thirty-five years, 1058 to 1093. The Norman victory at Hastings brought to the Scottish court, then at Dunfermline, a number of English refugees—these were a leaven of higher culture and refinement amongst the rude thanes and chieftains, and tended to further the advance of civilization, of letters and the arts of life, throughout the northern kingdom. And numbers of Normans also came and took service under Malcolm—and thus it came about that not only in England, but in Scotland also, most of the noble families have in them a strain of Norman blood.
