This MP may have been the son or grandson of Peter Belasise, bailiff of the Lincoln Staple during the 1360s and a prominent member of the local mercantile community.
Belasise played an important part in civic affairs for many years after his mayoralty. In both 1396 and 1397 he acted as an attorney at the Lincoln assizes for the municipal authorities, and in September 1398 he witnessed a deed on behalf of the corporation. He subsequently attested another conveyance for Robert Appleby, one of his successors as mayor. We do not know when he was made coroner, but the office was certainly in his hands by 1411, and he may have combined it with the post of alnager. The latter was awarded to him in 1413 for a period of five years, although he was replaced early in 1414 perhaps because of illness or even death. He left at least one son, who was obliged to petition Chancery for help in recovering certain unspecified property which his father had settled in trust for him upon one Thomas Somercotes. By marrying his daughter to the young John Belasise’s cousin and conveying the estates to them, Somercotes had fraudulently disregarded the terms of the agreement, but it is not clear if the couple were ever required to defend their title in court. Our Member and his wife, Maud, were remembered by the Lincoln merchant Seman Grantham, who made provision in his will of 1452 for masses to be said for their souls.
