MACKDUFF, Thane, afterward Earl of Fyfe.
A Thane in Ancient Times, is thought by the learned Spel|man and Selden, to have been the King's principal Minister in a Pro|vince, no doubt invested with a Power of Administration of Justice, to which certain honourary Priviledges were annexed. 'Tis thought it was not at the first Institution, properly a Title of Dignity, but of Service. They were of two kinds, either such as served the King in greater Places of Emi|nency, who were called Thani Ma|jores, or Thani Regis, as the Thanes of Fife, Caithness, Argyle, and Murray were, these that served under them were termed Thani Minores: But when the Title of Comes and Dux be|came Hereditary (so the Learned are of Opinion) the Title and Privi|leges of Thani Majores did descend with the Lands from Fathers to their Children, tho the lesser did not, yet they still retained the old Name of Thanes and Thanedoms, as the Ba|ronies of Boyn in Ba••ff shire and Cal|der in Murray, &c. are called to this Time: And perhaps the Difference betwixt the two consisted in this, That the greater Thanes derived their Power and Authority immediately from the King, and held them of the Crown in capite, for Knights Service, which by a certain Constitution made them Hereditary, and were of the same kind with them that after|ward came to be Parliamentary Ba|rons. The lesser Thanes, had only Commissions from them, and were held in the ordinary way for Services done, and to be done. All our Hi|stories do agree, that Mackduff, former|ly Thane, was created Earl of Fyfe, by King Malcolme Canmore, Anno 1057d 1.1, and that in Consideration of his ex|traordinary Services to that Prince, in assisting him to revenge his Fa|ther's Death upon Mackbeth, and to recover his Crown, for which he gave him and his Heirs these great and noble Privileges,
I. That his Posterity should have the Honour to place the succeeding Kings in the Chair of State, at their Coronations.
II. That they should lead the Van of the Royal Armies.
