Mayneld’s origins are obscure, although it is possible that he had some connexion with the borough of Colchester in Essex. He was resident in London by 1391, and probably for some time before, and in March that year he was among a number of denizen merchants who exported cloth through the port of London.
Mayneld himself may have been among the wealthiest members of his Company, and was apparently relatively secure. His business dealings, like those of many of the City’s greater merchants, concentrated upon the export trade, rather than upon domestic retail and distribution of goods. By 1401 he was exporting large quantities of cloth through the port of London, a few years later he had also built up trading connexions in Bristol, as well as closer to home in Kent and Suffolk, and he was among those who took wool to the continent through the Calais staple, where in 1423-4 his shipments amounted to more than 80 sacks.
Beyond the confines of his company, Mayneld first secured public office as one of the customs collectors in Great Yarmouth in Norfolk, an office which he held for just over a year at the same time as his second wardenship of the Grocers in 1408-9. This was, however, to remain an isolated Crown appointment, and his civic career in London was to remain equally undistinguished: in spite of his wealth and his four terms as a company warden he never rose beyond the city auditorship, the lowest rung on the city’s career ladder, serving just a single term in the office in 1413-14.
In the course of his business dealings Mayneld, like most merchants, came to be owed sums of money by numerous customers and other business associates.
The extent of Mayneld’s property in London is difficult to quantify, not least because of the problems in distinguishing transactions in which he acted as a feoffee from those where the buildings concerned were actually held by him. A rare exception was property in the parish of St. Mary Aldermary which he acquired from a fellow grocer, William Middleton, in February 1407 and which was settled upon Mayneld and his wife in May the same year. He also owned tenements in the parish of St. Alban Wood Street, but his principal residence was in the parish of St. Dunstan in the East where he served as a churchwarden.
Perhaps as a result of his public clash with the influential William Sevenoak, Mayneld failed ever to rise beyond the city auditorship. He nevertheless commanded some respect within his Company, and in 1420-22 served a further two-year term as one of its wardens. It was shortly after relinquishing this office that, on 19 Oct. 1422, he was chosen as one of the two representatives of the commonalty who were to attend the first Parliament of Henry VI’s reign. The reasons for Mayneld’s election are difficult to determine, but it is possible that it was related to the Grocers’ continuing efforts to protect their trade at this time. Certainly, among the business of the Parliament were matters like the confirmation of the privileges of the Calais staple, the question of the validity of the customs duties imposed upon the merchants of the Hanseatic league by the city of London, and the drop in the prices commanded by English cloth, purportedly as a result of the activities of alien brokers.
Mayneld drew up his will on 21 Mar. 1426, asking for burial in his parish church of St. Dunstan in the East, and leaving to his wife £80 above and beyond what she was entitled to by the custom of London. To each of his two daughters he bequeathed the sum of £50 along with various household goods, and left other cash bequests to friends and associates. His tenements in the parish of St. Alban Wood Street were assigned to his widow, after whose death they were to be sold and the profits divided between his daughters. Finally, ever conscious of the debts which were still owed to him, Mayneld left a total of £85 to his friend Thomas Southam on condition that he assisted his executors in recovering them. The date of probate is not recorded, but it is almost certain that Mayneld died before the end of the year. He was certainly dead by February 1427, when one of his executors, Robert Colbroke, came before the chamberlain of the City to deliver a sum of money which Mayneld had held in trust for the son of a London fishmonger.
