DUNBAR, George 10th Earl of Dunbar, Lord of Man and Annandale ¹

   User ID: Y879.

  General Notes:

"It was assumed by the older writers that he (George Dunbar 10th Earl) was the son of the ninth Earl by Agnes Randolph, notwithstanding that Boece, followed by Lindsay of Pitscottie, casts a doubt on that relationship,
plainly hinting that George was the son of a sister of Agnes.Boece indeed expressly says that Agnes Randolph had no issue, a statement not repeated by Pitscottie.

In an early MS. of Fordun's Annales also it is stated that Sir Patrick of Dunbar, who fought at Poictiers, and afterwards went towards the Holy Land, was the father of George, afterwards Earl of March. Sir Patrick's wife was Isabel Randolph, and as she was sister, and one of the two heiresses of John Randolph, third Earl of Moray, it is easy to explain how Earl George came to possess the Randolph estates as well as the earldom of March or Dunbar. His first appearance on record is in 1363, when, on 28 June, King David II. confirmed to him a grant of one-half of the baronies of Tibbers and Morton, in Dumfriesshire, which Patrick, Earl of March, and Agnes, his wife, had resigned in his favour."

from Scots Peerage ¹

George married Christiana SETON, daughter of Alan DE WYNTOUN and Margaret SETON heiress of Seton.^{1 2 3} (Christiana SETON was born about 1348.)

  Marriage Notes:

"The issue of this marriage (between Margaret, Lady of Seton, and Alan de Wyntoun) was : -
1. William, of whom below.
2. Margaret (or Christiana), who is supposed to have been married to George, tenth Earl of Dunbar."

from Scots Peerage (vol 8)




"The Earl (George 10th Earl) married a lady named Christiana, who is said to have been the daughter of Sir Alexander Seton of Seton .... " (page 273)

from Scots Peerage (vol 3)


"p. 273, 1. 24, delete whole line, and insert 'to have been a Seton but may have been the daughter of Alan de Wyntoun who married the heiress of Seton and seems to have taken her name (ex inform. Colonel the Hon. R. E. Boyle).' "

from Scots Peerage (vol 9 Addenda et Corrigenda)


Note:
The Scots Peerage (vol 3) quotation points to the father of Margaret being Sir Alexander Seton of that Ilk, 'the son', who married Margaret Murray.

Scots Peerage (vol 8), however, points out that the account by Andrew de Wyntoun of the abduction of Margaret was "heartily supported and aided" (page 570) by William Murray of Edinburgh Castle, brother in law of Sir Alexander Seton.

Footnote 4 of page 570 in Volume 8 adds:

"If Murray abetted De Wyntoun, the heiress can hardly have been, as some have held, daughter of the marriage between his own sister Margaret and Sir Alexander Seton 'the son,' which is mentioned above as recorded in the old Seton family pedigree."

The correction in Volume 9 confirms the parentage suggested in Volume 8. ^{1 2 3}
