George Dunbar, 10th Earl of March

"[5] 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.

George appears as second witness, styled 'cousin' of Sir Patrick (rather than 'nephew') and his wife 'black' Agnes Randolph, 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,[9] indicating both his extended family and that he was active in the management of the Dunbar family estates during Robert's reign.

In 1395, the Earl's oldest daughter Elizabeth was betrothed by contract to David Stewart, Duke of Rothesay, son of King Robert III and heir to the throne.

[5] In consequence of these events, George renounced his properties in Scotland and his allegiance to Robert III and moved the entire family to England, joining the court of King Henry IV.

On 28 June 1401, Henry granted, by Letters Patent, to "George de Dunbarre earl of the March of Scotland and Cristiana his wife" the lordship of Somerton in Lincolnshire, and the heirs male of their bodies, to be held by homage and military service.

On the same day Henry gave "George de Dunbarre earl of the March of Scotland" £100 sterling per annum "of his special favour" and in October granted him 'costs' of £25/9s/7d; and granted his wife "Cristiana countess of Dunbarre" £40/19s/3d "for her charges and expenses coming from the North at his command, to prosecute certain matters touching her husband, herself, and their heirs".

[20] In 1401 he made a wasteful inroad into Scotland, and in June 1402 he was victorious against a small Scottish force at the Battle of Nesbit Moor.

"Egged on by his very competent and energetic ally, the renegade Scotsman, George Dunbar", he drove his men across the Midlands towards Shrewsbury, raising more troops as he went.

[24] Between 14 and 18 August 1403, King Henry granted George de Dunbar, Earl of March, the ward of the manors and lordships of Kyme and Croftes in Lincolnshire, and a house and chattels in Bishopsgate, City of London, for life, which had previously belonged to the late Thomas Percy, Earl of Worcester, and was forfeited by his rebellion.

[27] Through the mediation of Sir Walter Haliburton of Dirleton,[28] reconciliation with the Douglases was effected in 1408, and he was allowed to return to Scotland the following year, taking possession of his earldom of March, but said to be deprived of the lordship of Annandale.
