Trevor was born at Glynde in Sussex, the family seat of the Trevors who had originated in 16th century Wales. He was educated at Westminster School and at Queen's College, Oxford, and became a fellow of All Souls in 1727. He became a canon of Christ Church, Oxford in 1735.
After his death, the estate of Glynde passed to his elder brother, Robert Hampden-Trevor, 1st Viscount Hampden.
Francisco de Zurbarán and Trevor
In 1756 Trevor purchased 13 paintings by Zurbarán, a series known as Jacob and his twelve sons, depicting the patriarch Jacob and 12 of his sons. Until 2011, when they were transferred, along with the castle, to a charitable trust backed by philanthropist Jonathan Ruffer, they were held by the Church of England at Auckland Castle in Bishop Auckland.
