Sir Roger L'Estrange, an English author, born at Hunstanton hall, Norfolk, in 1616, died in London, Dec. 11, 1704. He was the youngest son of Sir Hamond L'Estrange, and is believed to have been educated at Cambridge. During the civil war he was a zealous royalist, and in 1644, soon after the earl of Manchester had reduced the town of Lynn in Norfolk, L'Estrange received a commission from the king appointing him governor of the place if he could take it. He failed through the treachery of two of his associates, and being taken prisoner was sent to London, where he was condemned to death as a traitor. He was however reprieved, and remained a captive four years, until 1648, when he escaped to Kent. Here he attempted to raise an insurrection, but failing fled to the continent, where he remained until the dissolution of the long parliament (1653), when he returned to England, claiming that he was entitled to the benefit of the act of indemnity. His claim was not allowed; but having the boldness to apply to Cromwell in person, he was permitted to live unmolested. After the restoration he received the appointment of licenser or censor of the press. In 1663 he started a newspaper called the "Public Intelligencer," in which he warmly supported the crown.

After the popish plot he published (1679-'87) another newspaper called the " Observator," which was intended to vindicate the measures of the court. On the accession of James II. he was knighted, and sat in the parliament of 1685. He lost his office of censor at the revolution, and shortly after his mind failed. He wrote a great number of violent political pamphlets, and made many translations, chiefly from the Latin.
