An original 8-page vellum legal document with sewn binding, an "Instrument of Sasine," measuring 56 x 38 cm and dated 1742. "Sasine" is a Scottish legal term referring to the official transfer (“infeftment”) of feudal land or property, and such documents serve as the deed or registration of that transaction. This particular deed pertains to trustees for the Countess of Dalkeith and records an award to her of £400 per annum, equivalent to over £100,000 per annum today, the date of this document coincides with her marriage to Francis Scott, Earl of Dalkeith, see below. Provenance: Caroline, Countess of Dalkeith was Caroline Townshend, 1st Baroness Greenwich (née Campbell, 1717–1794). She was the daughter of John Campbell, 2nd Duke of Argyll, and Jane Warburton, placing her among the leading families of the British and Scottish aristocracy. In 1742, she married Francis Scott, Earl of Dalkeith, heir to the 2nd Duke of Buccleuch, and upon his death she was known as the Countess of Dalkeith. After Francis Scott’s death in 1750, Caroline married Charles Townshend in 1755 and had a daughter, Anne Townshend. In 1767, she was created Baroness Greenwich in her own right, reviving a title from her father. The barony became extinct on her death since she left no surviving male heirs by Townshend. Caroline is noted for her influential family connections, her marriages into two powerful British families, and for being the mother and grandmother of significant figures in aristocratic and literary circles. The document is robust and legible but with marks and two small holes centre right. The document will be shipped folded in half along the original crease line. The document includes the original duty stamps. Each page is witnessed by a group of signatories, confirming the importance of the document.
