Born into a liberal aristocratic family (see
Trevelyan baronets of Nettlecombe, 1662), Charles was the eldest son of
Sir George Trevelyan , and his wife Caroline, daughter of
Robert Needham Philips . He was the grandson of
Sir Charles Trevelyan , the elder brother of the poet
R. C. Trevelyan and the historian
G. M. Trevelyan, and the great-nephew of
Lord Macaulay. He was the great-great-grandson of
Sir John Trevelyan (1735–1828). Family legend traced their ancestry to Sir Trevillian, one of
King Arthur's knights, who swam ashore on horseback when the legendary land of
Lyonesse sank. The family kept three houses year round:
Wallington in Northumberland, which the family had owned since 1777,
Welcombe House in Warwickshire, and a town house in Westminster, No.14
Great College Street. The family estates comprised more than 11,000 acres. After
Harrow and
Trinity College, Cambridge, Charles Philips Trevelyan decided upon a political career.
Beatrice Webb, his friend, described him as "a man who has every endowment – social position, wealth, intelligence, an independent outlook, good looks, good manners". ==Life and career==
