Active at Hythe by the second decade of the fifteenth century, Prylle was involved in the affairs of the Port, particularly the repair of the haven, throughout Henry V’s reign. The upkeep of the haven was a personal interest, since he made his living principally from fishing, paying maltolts on large quantities of herring, mackerel and sprats. He was also a shipowner and ran some kind of passenger service. In 1413 Prylle was assessed as having goods and chattels worth £10, making him one of the dozen or so wealthiest men in Middle Ward, and in the following year he received an exemption from parliamentary taxation in the hundred of Folkestone.
Prylle was next recorded on 20 Jan. 1422 when he acted as surety for a plaintiff in the bailiff’s court, where he himself heard pleas as a jurat on the following 4 Apr.
Besides the evidence of his trading activities derived from his maltolt accounts, little record survives of Prylle’s private affairs. He certainly married and had at least one son (although the name of his wife remains unknown) and was a frequent litigant in the town’s courts. In 1422 the jury of the Hythe hundred court found that a wharf belonging to him obstructed the King’s highway and six years later the hundred jurors presented that he and John Skinner, his fellow MP in 1425, had fouled and obstructed the High Street near St. Nicholas’s church when cleansing a gutter.
Not among those named as jurats in February 1453, Prylle must have been an old man by that date. On 9 Jan. 1454 he appeared before the jurats of Hythe to account for his maltolts for the previous six years. As well as large quantities of mackerel and herring, Prylle had also been trading in billets of wood, and had amassed rents totalling £4 p.a., so he now owed £4 12s. 1d. He also agreed to pay a debt run up by his son, probably the Thomas Prylle who paid maltolts in West Ward.
