While not foremost among the Cambridge townsmen of his day, Rankyn was very much involved in the affairs of his borough. He had begun his career as an office-holder before entering the Commons, since he was one of the treasurers of Cambridge when elected as an MP. His parliamentary wages feature in the expenses section of the account of him and his co-treasurer, Thomas Sturmyn. Paid at the then standard daily rate of 2s., he received £4 10s. for the 45 days that he spent attending and travelling to and from Parliament, as did his fellow MP, Richard Bush*. In addition, the borough allowed him and Bush an additional 10s. in expenses for their part in negotiations between the town of Cambridge and the bishop of Norwich which took place in London while the Parliament was sitting.
The town’s relations with the university of Cambridge were much more fraught than any differences it might have had with the bishop. Following the involvement of the townsmen in the unrest that broke out in Cambridge during the Peasant’s Revolt, the town had forfeited its franchises. Although the Crown had restored these in 1382, it transferred certain important jurisdictional rights to the university. Relations between the town and university had again become bitter during Henry V’s reign and, no doubt to forestall a repetition of serious unrest, the practice grew up for representatives of the two sides to confer at an annual ‘Magna Congregatio’. In about 1423, shortly after he had ceased to be an MP, Rankyn attended one such ‘great congregation’ where he was among those representing the town’s suburbs.
In 1437 and again three years later Rankyn was involved in transactions concerning properties in Huntingdon but his interest in them is unclear. By this stage in his career he had become associated with Walter Cotton of Landwade, who had pursued a successful career as a mercer in London and was the father of William Cotton*. Together they took action against Robert Thorpe*, a merchant from the Suffolk town of Dunwich, for a debt of just over £28, in a suit which had led to Thorpe’s outlawry by May 1437. Twelve years later, John Thorpe of Stowmarket, presumably a relative of Robert, received a pardon for the outlawry that he had incurred after Rankyn and Cotton had sued him for the same sum.
Still active in the mid 1440s, Rankyn served his last recorded term as bailiff of Cambridge in 1446-7. In July 1446, not long before that term began, the King made a grant in frankalmoin of two tenements in Chesterton to Clare Hall, Cambridge, which he had acquired from several feoffees. Rankyn was among these trustees but for whom they were acting is unknown.
Rankyn did not live beyond the late 1440s. He was certainly dead by Michaelmas 1451, when his executors, the same Richard Togood and John Rankyn, took action for a debt of £14 in the borough court at Great Yarmouth against Robert Pynne* of that town.
