Margaret Coke, Countess of Leicester

Margaret Coke, Countess of Leicester (née Tufton, 16 June 1700 – 28 February 1775), also suo jure 19th Baroness de Clifford, was a British noblewoman and peeress.

She was born Lady Margaret Tufton, the third daughter of Thomas Tufton, 6th Earl of Thanet by his wife Lady Catherine, daughter of Henry Cavendish, 2nd Duke of Newcastle-upon-Tyne.

He was also 18th Baron de Clifford, and as he had no surviving male issue this title fell into abeyance between five co-heirs: Margaret, her two elder sisters Catherine (widow of Edward Watson, Viscount Sondes) and Anne (widow of James Cecil, 5th Earl of Salisbury), and her two younger sisters Mary (widow of Anthony Grey, Earl of Harold) and Isabella (wife of Lord Nassau Powlett).

The abeyance was terminated in Margaret's favour on 3 August 1734, and she became 19th Baroness Clifford in her own right.

Her husband, who had spent many years of his youth abroad on the Grand Tour, returned to England determined to build an English country house in the Palladian style.
