The first of this family was ALEXANDER, second son of William II, 40th Earl of Caithness, by his wife Mary, daughter of Sir William Keith of Inverugie. In 1507 Alexander Sinclair obtained a Crown charter of Stemster, He married Elizabeth Innes, evidently from what follows, of the family of Innes of Innes, whose chief had possession of Dunbeath in 1507, but on the resignation of Alexander Innes in 1529 a Crown charter was granted in favour of Alexander Sinclair of Stemster erecting Dunbeath, Reay and Sandside into a barony. The charter contains the following clause of some antiquarian interest: - "Cum mulierum merchetis, cum furca, fossa, sok, sak, thole, thieme, infangthief, outfanfthief, pit et gallows". The "mercheta mulierum " was (it seems) the right of levying a fine from a serf, or villain, on the marriage of his daughter.
I. ALEXANDER SINCLAIR had two sons and a daughter:
II WILLIAM SINCLAIR, SECOND OF DUNBEATH, was apparently a minor and unmarried when his father died, for in 1541, Oliver Sinclair of Pitcairn, styled also of Solway Moss, obtained a grant of his casualty of marriage, nor was he infeft as heir to his father till 1557.
In 1547 Dunbeath obtained from William Gordon, Treasurer of Caithness, and Rector and Parson of St.Magnus' Hospital at Spittal, a charter of Mybster and Spittal, confirmed by Queen Mary in 1565. In 1562 and 1564 he got from Adam, Bishop of Orkney, charters of Dounreay, Brubster, Thura, and other lands, for which a Crown charter of confirmation issued in 1557 (sic).
Dunbeath was twice married, first to Beatrix Gordon, daughter of either Alexander, Master [heir apparent] of Sutherland, or his son, Earl John, and secondly to Margaret, sole heiress of Alexander Innes of Innes and his wife Elizabeth, daughter of John, Lord Forbes. By these marriages William Sinclair had five sons, William, Richard and George usually stated as of the first marriage with Lady Beatrix Gordon, and Henry and David by Margaret Innes. It is, however, certain that William was a son of the latter.
In 1540 Margaret Innes had got from her natural brother; James Innes of Elrick, the lands of Over and Nether Monbeens; and in 1575 a precept was granted by her and her husband for infefting therein "William Sinclair of Stemster". Forbes in noticing this precept mentions him as the eldest son and heir of Dunbeath and Margaret Innes. Whether any of the other sons were certainly of the first marriage is uncertain.
William Sinclair of Dunbeath, who led a long and active life, was much harassed in his old age by his relation the Earl of Caithness. Among other acts of violence the Earl "wasted Dunbeath by fire and sword, and besieged him in his house at Dounreay", until be at length retired to Morayshire; among his wife's friends, and there died in 1608.
In the register of Confirmed Testaments, 1606-13, there is an entry of the "Testament Testamentar, latter will and legacy and inventory of the goods and gear of the deceased honourable man, William Sinclair of Dunbeath".
In the Register of the Privy Council there is a sederunt at Holyrood of date 27th May 1574, dealing with the attempt of Beatrix Gordon to recover her estates as she repudiated her marriage with Dunbeath. She describes the possession for "seven years by-past" of all her property by William Sinclair, which has put her to "such utter wrack" that if she "were not supported she had been able to perish, being put to such miserable case". The rents of Fisherne were appointed to her by the Lords of Council till the marriage cause should be settled by the head Commissariet, that of Edinburgh. She had been previously married to Alexander Innes of Cromarty. [Notes by T. Sinclair]
His sons were:
III WILLIAM SINCLAIR OF STEMSTER is supposed to have married the Lady Janet, eldest daughter of George II, 42nd Earl of Caithness, and dying during the lifetime of his father was succeeded by his son
In 1610 he resigned the barony in favour of his brother-in-law Arthur, Lord Forbes, in supersession of a deed by which he had entailed the estates on his kinsman the Earl of Caithness. [From History of the Scottish Clans]. He then withdrew from Caithness owing to the harassing conduct of the Earl, who is even accused of having contemplated his death, and resided with Lord Forbes.
Dying in 1624, Alexander, Master [heir apparent] of Forbes, sold Dunbeath to John Sinclair of Geanies, son of George Sinclair of Mey. The remainder of the barony and the lands of Spittal and Mybster were acquired by Sir Donald Mackay, first Lord Reay, who, in 1624, was infeft on a charter by the Bishop of Orkney, in Thura, Borlum, Dounreay, and Brubster; and about the same time Sandside was purchased from Lord Forbes by William Innes, ancestor of the family of Innes of Sandside.
