George de Dunbar, 10th Earl of March


George de Dunbar, 10th Earl of Dunbar and March (1338–1420), 12th Lord of Annandale and Lord of the Isle of Man, was "one of the most powerful nobles in Scotland of his time, and the rival of the Douglases."

Pitscottie states that this George is a son of John de Dunbar of Derchester & Birkynside, by his spouse Geiles (or Isabella), daughter of Thomas Randolph, 1st Earl of Moray (d. 1332). John was son of an Alexander de Dunbar, Knt. Alexander was a younger brother of Sir Patrick de Dunbar, 9th Earl of March. George succeeded his cousin or uncle Sir Patrick in his honours and estates, and appears in a charter dated 28 June 1363; and is second witness, styled 'cousin' of Sir Patrick and his wife 'black' Agnes, in another charter signed at Dunbar Castle on 24 May 1367. "Robetus de Lawedre, consanguineus noster" (a cousin) witnessed a charter of "Georgii comitis Marchie" relating to Sorrowlessfield, a still extant property on the (A68) road south of Earlston, Berwickshire, in the reign (1390–1406) of Robert III, indicating both his extended family and that he was active in the management of the Dunbar family estates during Robert's reign.

The Earl of March acquired the estates centred on the castles of Morton and Tibbers, with Morton likely becoming the centre of administration for both.

The Earl of March accompanied James Douglas, 2nd Earl of Douglas, in his incursion into England, and after the Battle of Otterburn (1388) he took command of the Scots, whom he conducted safely home. His daughter Elizabeth was betrothed by contract to David Stewart, Duke of Rothesay, son of King Robert III and heir to the throne, but Archibald Douglas, 3rd Earl of Douglas, 'The Grim', protested against the match, and through the influence of the Duke of Albany had the contract annulled, and had the prince married to his own daughter Marjory instead.
