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 Baronet, 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. 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.
