Priscilla Bertie, 21st Baroness Willoughby de Eresby
Priscilla Barbara Elizabeth Bertie, 21st Baroness Willoughby de Eresby was a daughter of the 3rd Duke of Ancaster and Kesteven and Mary Panton. On 23 February 1779, she married Sir Peter Burrell and they later had two children. Through her grandmother Mary Wynn, Priscilla Bertie was a descendant of the Welsh princely house of Aberffraw.
On 8 July 1779, her brother, the 4th Duke of Ancaster and Kesteven, died of scarlet fever at the age of 22 and his dukedom passed to his uncle, but his barony of Willoughby de Eresby, as well as the office of Lord Great Chamberlain, went into abeyance between Priscilla and her sister Georgiana Charlotte, the Countess of Cholmondeley. On 17 March 1780, however, the abeyance of the barony was terminated in Priscilla's favour, as the elder sister. The office of Lord Great Chamberlain remains divided.
