WARREN (THOMAS), senr., bookseller and printer in London, (1) White Horse in St. Pauls Churchyard, 1641; (2) Foster Lane, 1638(?)-61(?). Appears to have begun as a bookseller in partnership with Joshua Kirton. Their imprint (No. 1 above) is found on the title-page of James Giffard's French Schoolmaster, 1641 [Harl. 5927 (439).] Warren afterwards became a printer and was succeeded by his widow, Alice Warren, in 1661.
