CAVENDISH, Margaret, Duchess of Newcastle, famous in her day for her voluminous productions, was born about the end of the reign of James I., and was the youngest daughter of Sir Charles Lucas of Colchester. She married the Duke of Newcastle at Paris in 1645; and remained abroad till after the Restoration. On her return she wrote a vast number of plays and poems, together with the life of her husband, to the amount of about twelve folio volumes. "What gives the best idea of her unbounded passion for scribbling," says Mr Walpole, "was her seldom revising the copies of her works, lest, as she said, it should disturb her following conceptions." She died in 1673.
