The Trevelyan Papers, deposited by the Trevelyan family, are those of several generations of the Trevelyan family whose home was Wallington Hall, Northumberland. The archive is rich and diverse, not least because the family had so many roles and indulged so many interests between them that the archive can truly be described as multi-disciplinary.
George Otto Trevelyan (1838-1928) was an historian, Liberal M.P. and Chief Secretary for Ireland after the Phoenix Park murders. His papers also include items on astronomy and botany.
