Carwynnak’s family took its name from the manor of Carwinnick in the parish of Creed, and he himself held lands there, in neighbouring Grampound and in Liskeard, some of which had descended to him from his maternal uncle in about 1425.
By the late 1430s Carwynnak had settled at Plymouth, where he had acquired property through his marriage to Margaret, the widow and executrix of the merchant William Elys.
It is not clear whether Carwynnak played any part in the negotiations which eventually led to the incorporation of the borough of Plymouth in 1440, but he soon became drawn into the defence of the town’s new privileges. Thus, in early 1441 he appeared as attorney for the new borough in the court of common pleas, where the corporation defended its right to hear pleas in its own mayor’s court for the first time. Well equipped with a copy of the borough charter, Carwynnak proved successful in the plea, and the litigation in question pending before the Westminster justices was duly deferred to the jurisdiction of the mayor.
On this occasion, the burgesses had been joined in their opposition to the abbot of Buckland by the important local esquire James Chudleigh*, but it seems that over the next decade relations between them cooled, and in the spring of 1452 the King’s justices heard complaints from Chudleigh and another local esquire, Hugh Stucley, that a group of leading Plymouth gentlemen and merchants led by the mayor, Stephen Chapman, and the former mayor John Page, and including, among others, Carwynnak and Thomas Hill IV*, had assaulted their servants at Plymouth.
It seems that the former MP was nevertheless highly regarded by his neighbours who in 1457 chose him as mayor of the town.
The date of Carwynnak’s death is unknown, but he was evidently still alive in 1469 when he settled a tenement and ‘Capron’s garden’ in Plymouth’s Southtown on William Yogge and his wife.
