The medieval borough of Westbury consistently returned outsiders, rendering the identification of any one of its representatives precarious.
Grygge trained in the law, perhaps at London’s Middle Temple, of which he is known to have been a member in his later years.
Few other details of Grygge’s career have to come to light. It is not clear in whose interest he was returned for Westbury in 1450, but his return was undoubtedly connected with the efforts of John Mowbray, duke of Norfolk, and Richard, duke of York, to see their supporters placed in that year’s Parliament. In October 1450 Norfolk and York agreed on their choice of candidates to be knights of the shire for Norfolk, and the other dominant magnate in the region, John de Vere, 12th earl of Oxford, evidently acquiesced in their decision.
Grygge’s complete failure to attract public appointment before 1485, when the 13th earl of Oxford was in the ascendant, supports the supposition that he was a de Vere client. In 1489 he described Oxford as ‘my lord’, although the multiplicity of offices then held by the earl makes it impossible to know how their connexion had come about. That same year he was also finally appointed to Crown office, albeit in the somewhat inauspicious capacity of a tax collector.
Grygge died on 12 Aug. 1494, leaving his 19-year-old son Aubrey as his heir. By his will he had instructed his executors to take the revenues of his lands for nine years after his death and to use them for the payment of his debts and charitable works. Subsequently, they were to fall to Aubrey and his male heirs, with remainder in default to the testator’s daughter Alice. On account of his minority, Aubrey did not gain control of his inheritance for several years, and even a decade after his father death was still engaged in litigation against the latter’s executors.
