On 24 Oct. 1443 Goureley was singled out for special favour by the King: he was granted for life the castle and lordship of Horston in his home county of Derbyshire, to take effect from the end of 12 year-lease of Horston which the local esquire John Statham of Morley and John his son had been given by bill of the treasurer Ralph, Lord Cromwell, in 1439. Yet his expectations were dashed just a few weeks later on 19 Nov. when Statham and four of his sons were committed keeping of the castle for a term of 40 years.
Yet whatever his origins, Goureley made a name for himself as a professional administrator, through acquiring a level of expertise in financial matters. How he received his training in this field, whether in private estate administration or through employment by the Crown, is not known, but such was his reputation that, on 14 Mar. 1448, by the advice of the treasurer, Bishop Lumley of Carlisle, he was appointed along with John Byrston as a principal auditor of all accounts rendered by the King’s ministers in the Exchequer. The two men were to hold their important position for life, with the unusual guarantee that they would not be removed by any treasurer; nor, until their deaths, would the barons of the Exchequer admit anyone else in their place. Nevertheless, the patent was subsequently cancelled by royal warrant issued ‘for certain notable causes’ (no doubt opposition to this very provision, which barons and future treasurers would have found completely unacceptable).
