This MP appears to have belonged to the Joskyn family living at Cobham in Kent,
Although Joskyn’s duties at court continued to occupy most of his time, he sought to extend his private interests in Kent. On 7 Nov. 1449, styled ‘esquire of the King’s household’, he came to the court of common pleas to have enrolled a deed of the previous 23 Oct. whereby he confirmed to Edward Lymsey esquire and his wife Rose in tail, ‘his’ manor and advowson of Ifield and land at Cobham, Shorne and elsewhere.
Meanwhile, Joskyn had been assigned administrative tasks in the localities, initially, in December 1451, as a commissioner to arrest a number of men, mainly from Standon in Hertfordshire. The commission was politically motivated, for the manor at Standon pertained to the duke of York, who had given it for life to his retainer Sir William Oldhall*, currently in sanctuary for protection from the enmity of the duke of Somerset. Two months later York and his allies confronted a royal army at Dartford, before submitting to the King. In June 1452 Joskyn was instructed to escort a condemned traitor, John Wilkins, held responsible for stirring up a sizeable revolt in Kent in support of York’s army, from the Tower back to Dartford for his execution. It was subsequently alleged by a priest named Robert Collinson that while making a confession Wilkins had directed serious accusations of treason against Ralph, Lord Cromwell; but in testimony given on 31 Oct. the vicar of Dartford said that when the King’s officers had laid Wilkins on ‘le hurdill’ to draw him to the gallows he had asked Joskyn whether the condemned man should be confessed, whereupon Joskyn had replied that it was not necessary as Wilkins had had a confessor (not Collinson) at his side all day. This reported conversation had a part to play when Cromwell defended himself against the priest’s charges.
Joskyn failed to comply with the statutory requirement for MPs to be resident in the places they represented, for on 6 Feb. 1453, just four weeks before Parliament assembled, he had been designated ‘of Braughing, Hertfordshire, esquire’. This was when he had provided securities in £200 that John Hill, to whom the King had granted letters of safe conduct to bring a Spanish vessel to England, would guarantee that the letters would not be abused, allowing other ships to enter English waters.
In the meantime, Henry VI’s mental collapse had led to a reduction in the size of the Household, and when ordinances were drawn up for its regulation in November 1454 Joskyn was removed from his post as serjeant of the bakery, at least temporarily.
