Thomas de Quincey--hierophant, rhapsodist, philosopher--was born at Greenhay, then a suburb of Manchester, in Lancashire County, England, on the 15th of August, 1785. According to his own account, the family of the De Quinceys was of Norwegian origin; and after its transfer to France, in connection with William the Norman, it received its territorial appellation from the village of Quincy, in Normandy. Thence, at the time of the Norman Invasion, it was transplanted to England, where, as afterwards in Scotland, it rose to the highest position, not merely in connection with a lordly title and princely estates, but chiefly on account of valuable services rendered to the State, and conferring preeminence in baronial privilege and consideration. So sensitive was De Quincey, even at the early age of fifteen, on the point of his descent, lest from his name he might be supposed of French extraction, that, even into the ears of George III. (that king having, in an accidental interview with him at Frogmore, suggested the possibility of his family having come to England at the time of the Huguenot exodus from France) he ventured to breathe the most earnest protest against any supposition of that nature, and boldly insisted upon his purely Norman blood,--blood that in the baronial wars had helped to establish the earliest basis of English constitutional liberty, and that had flowed from knightly veins in the wars of the Crusades. Robert De Quincey came into England with William the Conqueror, uniting with whose fortunes, he fared after the Conquest as a feudal baron, founding the line of Winchester; and that he was a baron of the first water is evident from the statement of Gerard Leigh,--that his armorial device was inscribed (and how inscribed, if not memorially and as a mark of eminent distinction?) on the stained glass in the old church of St. Paul's.
