Administrative/Biographical history: The Wynn family of Boduan, Llŷn, 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 1549, receiving Bardsey Island as a gift of honour for his bravery. The Boduan 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 seat of their descendants. The estate descended in the male line until John Glynne (fl. 1644-1669), whose heiress, Francis married Sir Thomas Wynn (d. 1749).
Thomas and Francis'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 Caernarfonshire and Denbighshire. The combination of the three estates established Glynllifon as the foremost family in Caernarfonshire. Their son, Sir Thomas Wynn (1736-1807) was created a peer of Ireland in 1776, becoming known as Lord Newborough. He married secondly, Maria Stella Patronialla, who claimed to be the daughter of Louis 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 Bulkeley, 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).
