Comparatively little is known about this MP, who appears to have set up in business as a mercer by May 1390, when he shipped luxury goods worth almost £35 into the port of London. Two years later he took on the first of his recorded apprentices, accepting two more in 1395 and a fourth in 1398.
Sunningwell died between 30 Aug. and 4 Sept. 1400, and was buried in the church of St. Thomas Acon. To his widow, Alice, he left a cash sum of £200, as well as the customary third of his goods. The other leading beneficiary of his will was Adam, the son of the mercer, John Feraunt, who received £80, perhaps because the deceased had once been his father’s business partner or apprentice.
