SIR EDWARD DE KEITH, great-uncle, being brother of the first Sir Robert, and in remainder to the lands of Keith and the Marshalcy, under the entail of 1324, succeeded his great nephew. In 1328 he had a charter from King Robert, witnessed by Robert de Keith, Marischal, of the lands of Kelly, &c., to be held in free barony by the service of one knight in the King's army. It is recorded that neither Sir Robert nor he came to the battle of Halidon Hill, 1333, where his son William was taken prisoner. He had, of the inheritance of his wife, the hereditary sheriffdom of Selkirk. He married, before July 1305, Isabel, daughter of Alexander DE SYNTON, and sister and heir of Andrew DE SYNTON, taken prisoner at the battle of Dunbar, 1296, who. afterwards died a prisoner in Fotheringhay Castle. He appears to have been slain at the battle of Neville's Cross, 17 October 1346. [Complete Peerage VIII:471]


XIV - Sir Edward Keith, designed "son of Robert de Keith great Marischal of Scotland," appears on an inquisition in 1341. He died before 1350. He married (1st) Isabel de Keth of Galstoun, and (2ndly) Christian, daughter of Sir John Menteith and Elyne of Mar, by whom he had a daughter, Janet, who marrying Sir Thomas Erskine, became ancestress of the Erskines Earls of Mar.

Sir Edward had two sons - Sir William, and John (designed in 1354 the son of Sir Edward and brother of Sir William great Marischal of Scotland). John, marrying Mariota, daughter of Sir Reginald Cheyne of Inverugie, began the line of the Inverugie Keiths. Of two daughters of Sir Edward, Catharine married Alexander Barclay, ancestor of Barclay of Ury, and Janet married Sir David Hamilton, of Cadyow. The manuscript gives another Edward, whom it describes as the first Lord Keith, and the father of Janet, Lady Hamilton. [The Scots Peerage VI:33]


William was son of Edward I de Keith of Sinton, and Isobel de Sinton of Sinton. He was Marischal of Scotland, as successor to his uncle Sir Robert Keith. He has been conflated with his father in many pedigrees of the family. He, not his father, succeeded at Marischal.

  • Keith, William (d.1407?) by Henry Paton
  • KEITH, Sir WILLIAM (d. 1407?), great marischal of Scotland, eldest son of Sir Edward Keith, great marischal, who was brother of Sir Robert Keith, great marischal [q. v.], and his first wife, Isobel de Keith, succeeded his father about 1350. He took an active part in the arrangements with the English government in 1357 for the ransom of David II (Bain, Calendar, iii. 302), with whom he is said to have been in much favour. He and Thomas, thirteenth earl of Mar, are reported to have fought a duel at Edinburgh, when the king showed such open partiality for Keith as to provoke Mar into making a public protest. Thereupon David laid siege to Mar's castle of Kildrummy (Scalacronica, p. 203). Keith went abroad in 1358 for a time to seek renown in foreign wars (Rotuli Scotiæ, i. 830). He was employed in 1369 to negotiate a truce with England at London (Rymer, Fœdera, iii. 878), and in March 1371 was present at the coronation at Scone of Robert II.
  • He married Margaret, only daughter and heiress of Sir John Fraser (son of the chamberlain) and Mary Bruce. Their principal residence was at Kintore until in 1392 Keith exchanged with William, Lord Lindsay of the Byres, who had married his daughter Christian, certain lands in the counties of Fife and Stirling for the Crag of Dunnottar in Kincardineshire. Here he built the celebrated castle of Dunnottar, and made it his chief fortress. Before the works began he had to remove the parish church to another part of the lands, and on the plea that he had invaded consecrated ground Keith was laid under a sentence of excommunication by the Bishop of St. Andrews. He appealed to Rome, and on 18 July 1394 Pope Benedict XIII granted his bull, removing the censure, and permitting the castle to remain on the old ecclesiastical site, on condition of an annual composition being paid to the church (Hist. MSS. Comm. 3rd Rep. Appendix, pp. 405, 409). Keith died between 1406 and 1408. He had three sons and four daughters; one of the latter married Robert, duke of Albany, governor of Scotland.
