Administrative / Biographical History

The origins of the Wynn family, Lords Newborough, lie with the Wynn family of Boduan, Llyn, who claimed descent from Cilmin Troed-ddu. John Wynn was standard-bearer for Edward VI in the fighting near Norwich against Ket and his co-rebels in 1594, receiving Bardsey Island as a gift of honour for his bravery. The estate then descended in the male line. Sir Thomas Wynn (d. 1749) married Francis, daughter and sole-heiress of John Glynne of Glynllifon, thus uniting the Boduan and Glynllifon estates. The Glynne family had acquired Glynllifon by the marriage of Tudur Goch and Morfudd; which became the chief seats of their descendants. It descended in the male line until John Glynne (fl. 1644-1669), whose heiress, Frances married Sir Thomas Wynn (d. 1749). Thomas and Frances's heir was their son Sir John Wynn (1701-1773), 2nd Bart., who through his marriage to Jane Wynne acquired the Melai and Maenan Abbey estates in Denbighshire and Caernarfonshire. Their son, Sir Thomas Wynn (1736-1807) was made an Irish peer in 1776, becoming known as Lord Newborough. He married secondly, Maria Stella Patronialla, who claimed to be the daughter of Lois Philippe, Duke of Orleans, afterwards King of France, although it was never proved. According to the 1873 return of owners of land, Lord Newborough owned an estimated 28,800 acres in Wales (in Caernarfonshire, Merionethshire, Denbighshire and Anglesey), with an estimated rental of £22,728. On the death of Spencer Bukeley, 3rd Baron Newborough in 1888, the title passed to his grandson, William Charles Wynn (1873-1916), 4th Baron Newborough, while the estates went to his youngest son, Frederick George Wynn (1853-1932). On Frederick's death in 1932, the estate reverted to Thomas John Wynn (1878-1957), 5th Baron and brother of William Charles Wynn. Charles Henry Wynn (1847-1911), third son of Spencer Bukeley Wynn (1803-1888), 3rd Baron, succeeded to the Rug estate in Merioneth, pursuant to the will of Sir Robert William Vaughan in 1859. According to the 1873 return of owners of land, the Rug estate measured an estimated 10,504 acres, all in Merionethshire, with an estimated rental of £8,905. The Rug estate had originally been in the hands of the Salusbury family, who acquired the estate upon the marriage of Piers Salusbury of Bachymbyd to Margaret Wen, daughter and heiress of Ieuan ap Hywel ap Rhys, lord of Rug. On the death of William Salusbury, who had inherited the estate from his nephew, John, the estates were split up. Owen Salusbury (d. 1657), William's eldest son, received the Rug estate. He married Mary, daughter and heiress of Gabriel Goodman of Abinbury, Porthonotary of North Wales in 1625, adding further lands to the Salusbury estate. Owen's grandson, Owen Salusbury (d. 1694), left two daughters. The Rug estate was inherited by his eldest daughter Elizabeth, and subsequently by her daughter, Maria Charlotte (1721-1780). She left Rug by her will to Edward William Vaughan (d. 1807), second son of Sir Robert Howel Vaughan of Nannau and Hengwrt. On Edward's death in 1807, the estate passed to his younger brother, Griffith Howel Vaughan (d. 1848). It subsequently passed to his nephew, Sir Robert Williams Vaughan from whom it passed to Charles Henry Wynn (1847-1911). On the death of Thomas John, 5th Baron in 1957 the title passed to his cousin, Sir Robert Vaughan Wynn (1877-1965), son of Charles Henry Wynn (1847-1911).

Custodial History

Parts of the Glynllifon and Rug papers were originally held at the National Library of Wales. In the course of re-cataloguing these, and assimilating the many documents not previously available into the collection, the number scheme has had to be reorganized. In order to facilitate the identification of documents previously having an National Library of Wales call number, the old National Library of Wales call number is entered at the end of the relevant numbers.
