Notes for Earl Thomas STEWART 2nd Of Angus
John Stewart, Earl of Angus, married, in terms of a papal dispensation of date 24 October 1328, Margaret, eldest daughter and co-heiress of Sir Alexander Abernethy, by which marriage the lordship of Abernethy in Perthshire and other lands passed into possession of the Earls of Angus.

By her, the Earl had one son,

Thomas, who succeeded.

Margaret Abernethy, Countess of Angus lived until about 1370, surviving her son as well as her husband.

II. Thomas Stewart, second Earl of Angus, was only an infant at his father’s death,
and does not appear on record until 1353 in the dispensation for his marriage, the petition for which was seconded by John, King of France, in terms which suggest that the Earl’s youth was probably spent at the French Court.

He was at the siege of Berwick in 1355, and in the following year was a member of the embassy to London, which negotiated for the release of King David II. He acted for some time as chamberlain of Scotland, but for alleged complicity in the murder of Catharine Mortimer, mistress of King David II, he was imprisoned in Dumbarton, and there fell a victim to the plague in the year 1361.

In terms of the dispensation already referred to, Thomas, Earl of Angus, married Margaret, daughter of Sir William Sinclair of Roslin, who survived him, and married secondly, Sir William [sic - John] Sinclair of Herdmanston, to whom she bore several children.

By Margaret Sinclair, the Earl had two daughters, co-heiresses:

1. Margaret
2. Elizabeth,
who married Sir Alexander Hamilton, son of John Fits Walter or Hamilton …

Thomas, second Earl of Angus, also had a son, evidently a natural son, who was styled William Stewart of Angus, and is described by his sister, Margaret, as her brother.

VI. SIR WILLIAM [sic] ST.CLAIR, NEXT OF HERDMANSTON. allied in marriage with the other ancient, but far more powerful, family of the St.Clairs of Roslyn, who, in truth, exceeded most other families in the kingdom for grandeur and wealth. His lady was Margaret [daughter of William St.Clair of Roslin], afterwards Countess-Dowager of Angus.

Being within the fourth degree of relationship, she had obtained in 1353 a papal dispensation to marry Thomas Stewart, Earl of Angus, Chamberlain of Scotland, in 1357.

The Earl died in Dumbarton Castle about, and not later than, 1362 - when an entry appears in the Rolls for his funeral expenses - leaving issue by Margaret St.Clair a daughter Margaret, in her own right Countess of Angus, on whose resignation, in 1389, her natural son George -by William, Earl of Douglas - obtained a charter of that Earldom.

King David had, in 1342, assigned to John de St.Clair the thanage of Cowie (Colby) in place of a pension of £20, and in the 34th year of his reign - 13th April 1364 - King David granted a charter to Margaret de Santo Claro, Countess of Angus, for £20 sterling annually from the same thanage of Colby.

By this noble lady Sir William [sic] had three sons -

1 JOHN, next of Herdmanston
2 JAMES, probably first of Longformacus
3 SIR WALTER, Baron of Cessford, whose heiress - CHRISTIAN, married Sir William Cockburn, who disputed about the Barony of Cessford in 1416.
