John may have been the son of a namesake living in Lewes in the 1370s and 1380s.
In 1425 Parker had acquired a garden at Lewes from Robert Smythwyk. The full extent of his property holdings is not known, but he would appear to have prospered, for in January 1427 he and his wife were able to procure a papal licence to choose their own confessors. By 1429 he had purchased land at Ringmer near Lewes, and to this he added two messuages and some 70 acres in the course of the next few years, later coming to be described as a ‘husbandman’.
