Plas Nantglyn was built in 1573. The estate descended in the male line of the Wynne family until 1743 when, on the death of Thomas Meredith Wynne, it passed to his aunt and co-heiress, Mary Wynne. Her daughter, Margaret Parry, married Edward Cadwaladr (b. 1687), and it was with their sons that the surname Edwards became associated. On the death of their eldest son, Hugh Edwards (1721-c. 1787), without issue, the estate passed to his brother, Evan Edwards (1726-1796). Evan's heir was his only son, the Rev. Thomas Wynne Edwards (1796-1877), vicar of Rhuddlan from 1828 until his death. He married Eliza Gardner William (1797-1884), daughter of John Copner Williams, a Denbigh solicitor, and was succeeded by his eldest son, John Copner Wynne Edwards (1821-1886), also a solicitor in Denbigh. John married Maria, daughter of Wood Gibson of Hope, Lancashire. John Copner Wynne Edwards was succeeded by his eldest son, Thomas Alured Wynne-Edwards (1855-1925), an engineer by profession. He served as a Volunteer and Territorial officer, commanding, with the rank of Colonel, the 4th Battalion Royal Welsh Fusiliers, 1908-1913, being appointed its Honorary Colonel in 1919. His son and heir was Lieutenant Colonel John Copner Wynne-Edwards (1890-1967).
