Fonds GB 0210 GWYBRA - Gwydir (BRA) Papers,

The Wynn family of Gwydir claimed descent from Owain Gwynedd's second marriage to Christiana, daughter of Goronwy ap Owain ap Edwin, lord of Englefield. The first of the family to use the name Wynn, twelve generations later, was Morris Wynn (d. 1580), son of John ap Meredydd (fl. 1544-1559). His son Sir John Wynn (c. 1553-1626) was created a baronet in 1611, and was the author of The History of the Gwydir Family. His grandson, Sir Richard Wynne (d. 1674), the fourth baronet, was succeeded by his daughter Mary, his sole heiress. The baronetcy devolved to his cousin, Sir John Wynne (1628-1719) of Wattstay (who changed the name to Wynnstay); the baronetcy became extinct on Sir John's death, and the Wynnstay estate passed to his kinsman Sir Watkins Williams (d. 1749) who founded the Watkins Williams-Wynne family of Wynnstay.

In 1678 Mary Wynne married Robert Bertie (1660-1723), 1st duke of Ancaster and Kesteven, and carried the Gwydir estate into that family. The 4th duke dying unmarried in 1779, the Ancaster, Kesteven and Lindsey titles passed to his uncle, while the rest of his titles fell into abeyance between his two surviving sisters, his heirs general, who also received his estate. The elder sister, Priscilla Barbara Elizabeth Bertie (1761-1828), married, in 1779, with Peter Burrell (d. 1820), and secured the Gwydir estate, the Grimsthorpe Castle estate in Lincolnshire, and the title of Baron of Willoughby de Eresby. Her husband was created Baron Gwydir in 1796, and acted as his wife and sister-in-law's deputy in the hereditary office of Lord Great Chamberlain of England. His son, Peter Robert Burrell (1782-1865), 21st baron Willoughby de Eresby and 2nd baron Gwydir, married Clementina, daughter and sole heiress of James Drummond, Lord Perth, and took the name Peter Drummond-Burrell.

He was succeeded by his only survivning son, Alberic Drummond-Burrell (1821-1870), 22nd baron Willoughby de Eresby and 3rd baron Gwydir. In 1829, he and his sisters took the surname Drummond-Willoughby in lieu of Drummond-Burrell. He died unmarried and the Barony of Gwydir devolved on his cousin and heir male, while the Barony of Willoughby de Eresby again fell into abeyance between his two surviving sisters, his heirs general. Clementina Elizabeth (1809-1888), the elder daughter, secured the title. She had married in 1827 with Gilbert John Heathcote (1795-1867), son and heir of Sir Gilbert Heathcote, baronet, of Normanton Park, Rutland. In 1872, she took the name Heathcote-Drummond-Willoughby in lieu of Heathcote for herself and her issue.

According to the 1873 return of owners of land, the Gwydir estate amounted to an estimated 30,391 acres in Caernarfonshire and 296 acres in Denbighshire, with an estimated rental of £8,521. Baroness Willoughby de Eresby also owned an estimated 24,696 acres in Lincolnshire (£36,520) and 76,837 acres in Perthshire (£28,965), giving her a total of 132,200 acres with a rental of £74,000, and making her the 17th largest landowner (with the 12th largest rental) in the United Kingdom. This is irrespective of the Heathcote family estate, held by her son, Gilbert Henry Heathcote-Drummond-Willoughby (b. 1830), second baron Aveland, which consisted of about 17,600 acres (£27,000) in Lincolnshire and 13,600 acres (£20,000) in Rutland.

The Gwydir estate was sold in or about 1895 to Charles Robert Carrington, Baron Carrington of Bulcot Lodge and Baron Carrington of Upton, who was created Earl Carrington in the same year. His mother was Charlotte Augusta Annabella Drummond-Willoughby (1815-1879), the younger surviving sister of Alberic, 22nd baron Willoughby de Eresby, above. In 1880 he changed his name to Carington, and in 1896 to Wynn-Carrington.
