Probably originally from outside Bishop’s Lynn, Cony became a freeman of the borough on 16 July 1438, having served an apprenticeship under Thomas Spicer*.
Within a decade of becoming a freeman, Cony served a term as a chamberlain in Lynn, often a preliminary office for those seeking positions of higher responsibility within the borough, and he gained admission to the 24, the higher council that dominated local affairs, in May 1449. He subsequently served five times as mayor, and he became alderman of the Trinity guild in 1465, an office of far greater importance than his previous position of master of the lesser guild of Corpus Christi. It was in his capacity as alderman that he was obliged to take over the mayoralty for a fifth term, following the death in office of Thomas Leighton in December 1476.
Like other leading burgesses, Cony was often busy with tasks not specifically related to any particular office in the borough. In 1456, for example, he arbitrated in a dispute about a tenement, and he represented the borough in discussions with its feudal lord, the bishop of Norwich two decades later. He was also one of those who negotiated with the Crown in 1473, when the corporation was seeking the right to hold a fair, and among the merchants who met the royal council in London on another occasion that year, to discuss England’s relations with the Hanseatic League.
Unlike his fellow envoy, Bermyngeham, Cony sat for Lynn in only one Parliament, that of 1455. He and Henry Thoresby* were elected to the Commons on 3 July and received a warrant of attorney from the corporation two days later, when a lawsuit in which Cony was engaged with Walter Monk, master of the hospital of St. John the Baptist in Lynn, was suspended. Cony would also have sat in the first Parliament of Edward IV’s reign, had circumstances allowed. This assembly was to have opened in the summer that year, but the King postponed it in order to deal with armed opposition in northern England. By then, the electors of Lynn had returned Thoresby and William Caus† as their MPs, but at a fresh election in September they elected Cony and Bermyngeham instead. Following another postponement, they met again in October to return Bermyngeham and Simon Pygot*. Cony was involved in at least two other parliamentary elections, since he was one of those who elected Lynn’s MPs to the Commons of November 1449, and in October 1470, during his third term as mayor, he nominated four of the 12 electors who chose Bermyngeham and Robert Braybrooke† to represent the borough in the Parliament of that year.
By the early 1470s, Cony thoughts were turning to the hereafter. In this period he built a tomb chapel dedicated to the Holy Trinity (although commonly known as ‘Cony’s chapel’) in St. Margaret’s, the parish church of Lynn, and erected the transept in the same church. He also began work on clerestories on both sides of the nave, a project still in progress when he died on 29 Sept. 1479. It would appear that he died childless, although his then wife, Margaret, had a daughter by a previous marriage. His will has not survived, but he is known to have appointed as his executors Edmund Westhorpe, John Burbage† and John Burton, who completed his building projects at St. Margaret’s in 1481. Cony also left £20 towards the completion of the church’s north-west bell tower, but the spire intended for the tower was never built and some years later the executors presented the church with a silver-gilt cross and banner instead. The brass on Cony’s tombstone, an ornate construction of Purbeck marble, depicted a man in the costume of a burgess or merchant with a rosary and a purse attached to his belt. Removed to make room for another burial in 1701, the stone was returned without its brass during later restoration work on what was left of his chapel. Besides his tomb, Cony’s house was another reminder to future generations of burgesses of the position that he had held in their borough. A large and ornate timber-framed building built in the middle of the fifteenth century, it stood on the corner of the high street facing St. Margaret’s until it was demolished in 1816.
