Mary Sackville, Countess of Falmouth and Dorset (1645 – 1679, née Bagot) was a British courtier and mistress of King Charles II.[2] The King rewarded her with grants of land, including Somerset House, in the Strand,[3] and a state pension.
Mary Bagot (c. 1665- 18 April 1693), married Gilbert Cosins Gerard (1662-1720) on 2 May[5] 1681, divorced in 1684.[4]
After the death of Anne Hyde, Duchess of York, in 1671, Mary was briefly considered as a possible bride for the widowed Duke of York, who later became King James II.[6] She was discounted due to her relationship with his brother the King.[7] James instead married Mary of Modena.[8]
Mary died in childbirth on 12 September 1679 and was buried at Withyan, Sussex.[5]
She was one of the Windsor Beauties painted by Sir Peter Lely.[9] Her portrait by Lely was erroneously named "Elizabeth, Countess of Falmouth" and also as "Countess of Ossory" in some portrait prints and books in the 18th and 19th centuries, many of which were later reprinted, compounding the error.
