Of the early days of his son John, nothing is known. He was educated at Brasenose College, where he was the first lecturer or scholar on his father’s foundation. At the coronation of King Edward VI. he was made a Knight of the Bath. Like his father, he married twice. His first wife was Elizabeth, daughter of Sir Thomas Giffard, by whom he had two sons, who predeceased him, and three daughters—Elizabeth, who married Sir Thomas Gerard, Knt., of Bryn; Dorothy, who married George Hastings, Earl of Huntingdon; and Margaret, who married Sir Thomas Stanhope, Knt., of Shelford. From whom the present hereditary Governors of Repton School, Lord Gerard, Earl Loudoun, and Earl Carnarvon, trace their descent. His second wife was Dorothy, daughter of Sir Anthony Fitzherbert, of Norbury, by whom he had no children. In the year 1553 he was one of the “Knights of the Shire” for the county of Derby, and served the office of High Sheriff for the same county in 1554. In August, 1556, he “sat with the Bishop of the diocese (Ralph Baine) and the rest of the Commissioners, at Uttoxeter, in Staffordshire, to search out heresies and punish them.” (Strype, Memorials, vol. III., part 2, p. 15.) Joan Waste, a blind woman, was tried and found guilty of heresy, and was burnt at the stake in Derby. By will, dated the 6th of June, 1557, among many other bequests, he gave and devised to his executors, Sir Thomas Giffard, Richard Harpur, Thomas Brewster, John Barker, and Simon Starkey, all his lands, tenements and hereditaments, in Mosley, Abraham, and Brockhurst, in the county of Lancaster, to find a Priest, well learned and graduate, and of honest and virtuous conversation, freely to keep a Grammar School in Etwall, or Repton, also an Usher associate to and with the said master, to keep the School. The School Master to have yearly twenty pounds, and the Usher ten pounds. Also that his executors should hold, for the term of seven years after his decease, his farm called Musden Grange, and with the profits should find a priest to say Mass, &c., for seven years, and with the residue of the profits of the stock and farm should build a substantial school-house with convenient chambers and lodgings for the schoolmaster and usher in the precinct on the north side of the churchyard of Etwall, or at Repton, and this being done, without delay, to establish, by the King and Queen’s license, and other assurances to the School for ever. He also willed that Sir William Perryn, Bachelor of Divinity, his late Chaplain, should be (if living and willing) the first Schoolmaster. As the Report, made to the Charity Commissioners by F. O. Martin, Esq., in 1867, says, “Sir John had no property in Repton. His executors were probably induced to establish the school there, rather than at Etwall, by finding the remains of the dissolved priory well adapted to the purpose.”
