BRAMPTON or BRANDON, SIR EDWARD, Anglo-Jewish adventurer of the 15th century. Born in Portugal of Jewish parentage, he came to England in maturity and was baptized under the auspices of King Edward IV., whose name he adopted. From 1468 to 1472, with a brief interval, he was an inmate of the Domus Conversorum in London, with an allowance of Ind. a day. Subsequently, he entered public life, receiving a series of military appointments, and being rewarded with grants of land and of mercantile privileges. In 1482 he was appointed captain, keeper, and governor of Guernsey, which office he re tained until the fall of the Lancastrians. He became a zealous partisan of Richard III., by whom favours were showered upon him, and was knighted in 1484. After the accession of Henry VII., he retired, first to the Low Countries, and then to Lisbon. At Middelburgh, there entered into his service a Flemish youth named Perkin Warbeck, who later, when he made his bid for the throne of England, made full use of his master's recollections of the court of Edward IV. In 1488, Brampton is found, incredibly enough, again resident in the Domus Conversorum in London: but he afterwards went back to Lisbon, where he entertained the English embassage in the following year. Through their medium, apparently, Sir Edward Brampton received a full pardon from Henry VII. in 1489, and returned to England. A son of his was knighted by the king at Winchester in 150o.
