The Vyvyans /ˈvɪviən/ are a prominent Cornish family who were members of Parliament, baronets, and landowners in Penwith and Kerrier since the 15th century. The Vyvyan family have held the large Trelowarren Estate in the parish of Mawgan-in-Meneage in west Cornwall for nearly 600 years. They moved to Trelowarren in 1427 from Trevegean, St. Buryan when they acquired Trelowarren through marriage to the daughter of Honora Ferrers, heiress to the estate of the previous owner, Richard Ferrers. Trelowarren's first garden (at least under the Vyvyans) is recorded in 1428. In the English Civil War (1642–1651) the Vyvyans were royalist supporters. Sir Richard Vyvyan (1613–1724), 1st Baronet, was given a large equestrian portrait of King Charles I (1600–1649), a copy of the famous painting by Anthony van Dyck, by King Charles II (1630–1685) in recognition of his support.^[2]
