Wyndham was born at the family estate, Petworth House, in Sussex. A direct descendant of Sir John Wyndham, he was the fourth (but third surviving) son of Henry Wyndham, 2nd Baron Leconfield, and Constance Evelyn Primrose, daughter of Archibald Primrose, Lord Dalmeny. His grandfather, the first Baron Leconfield, was the adopted heir of George Wyndham, 3rd Earl of Egremont, from whom the family derived their considerable wealth.[1]
Hugh was educated at Eton College and New College, Oxford.
In 1908, he married Maud Mary Lyttelton, daughter of Charles Lyttelton, 8th Viscount Cobham. She died in 1953, one year after he inherited the family titles from his older brother.
He did not move to the family estate in Petworth but primarily resided at Wyndham House in London.[2] He died at the London Clinic in 1963, 11 years after inheriting the title.
Like his two elder brothers, Hugh had no children, and the title passed to his younger brother, Edward Wyndham.
