 The successive Lords of the manor of Pishiobury had local hunting rights and their own park, too.In 1248 William de Saye granted the heiress of Pishiobury, Margaret FitzGerold/FitzeWarin, wife of Baldwin de Redvers, the right of free hunting on her own estate with dogs, birds or nets, and free fishing in the river where it joined her lands; in return she recognized the de Sayes' right to have free warren over the whole Sawbridgeworth, including Pishiobury.This agreement shows how the right of other manors developed out of the original manorial powers of John, Lord Robert Lisle's son, kept of underwood from the land called Vodeleye; the park of Gedelesho and Gedelesho Wood (Gilston) and its keeper are mentioned, so presumably this was the manorial park.
