The Carminowes were an ancient Cornish family who took their name from the family’s principal seat in the parish of Mawgan in Meneage. The senior branch of the family came to an end with the death in 1396 of Joan, daughter and sole heir of Thomas Carminowe of Carminowe, when her estates were divided between the descendants of her great-grandfather’s two sisters, Sir John Arundell I* of Lanherne and John Trevarthian† of Trevarthian. A junior branch of the Carminowes was established in the reign of Edward II by Sir John Carminowe, a younger son of Roger de Carminowe†, and by the 1380s their wealth, centred on the manors of Boconnoc in Cornwall and Ashwater in Devon, outstripped that of the main line. The Carminowes of the younger branch, unlike their cousins, were prolific, and on the accidental death in 1386 of Sir Ralph Carminowe†, who was dragged over a cliff by his own hounds, their lands passed to his brother, Sir William.
Thomas, the later MP, was the second of Sir William’s four surviving sons. As his elder brother, John, produced a son and heir, he initially had little hope of ever succeeding to their father’s lands, but the deaths of John and his young son of the same name within a short time of each other changed all of this, and in 1420 the 25-year-old found himself in possession of the Carminowe lands.
At the time of John Carminowe’s death in 1420 Thomas and his younger brother Walter may still have been in France, where they had gone the previous year in the retinue of William, Lord Botreaux.
His inheritance made Thomas one of the most substantial landholders in Cornwall, and he assumed the traditional position of the head of his family in county society. In November 1423 he was pricked sheriff, three years later he was elected to Parliament for the first time, and he was subsequently appointed to a string of ad hoc commissions in the region. Moreover, he and his brothers also maintained a regular presence in the county court. Thomas himself attested the shire elections of 1429, 1431 and 1433, his brother Nicholas all those held between 1429 and 1435 and subsequently those of 1442, January 1449, 1455 and 1467, and the third brother, Walter, all those held between 1429 and 1435.
Along with his landed wealth, Carminowe owed much of his influence to his extensive connexions among the gentry of the south-west. His elder brother John had married Alice, daughter of Sir John Dynham of Nutwell, the wealthiest landholder in Devon after the Courtenay earl.
This is not to say that Carminowe enjoyed cordial relations with all of his neighbours. He may have been a somewhat litigious man, for in the summer of 1440, when he accused the Launceston gentleman Thomas Tregodek* and John Bydelake, one-time steward to the Tremayne family, of waylaying and attempting to kill him in the London parish St. Dunstan in the West in November 1437, he described his urgent business that they had prevented him from attending to as ‘informandum homines in lege eruditos de consilio suo tam de impetracione brevium, quam prosecucione et defensione diversarum accionum pro eo et contra eum in curia domini Regis tunc hic motarum et movendarum’.
In 1436 Carminowe’s Crown appointments suddenly dried up, possibly as a result of a violent disagreement with his distant kinsman, Sir William Bonville. Until the early months of the year, their relations had apparently been cordial enough, and Bonville had even paid Carminowe a sum of money in return for his assistance in the purchase of the manor of Tywardreath from Sir John Herle*. It seems, however, that Carminowe had other ideas, and was planning to keep the manor for himself, once he had gained possession. By February 1436 Tywardreath had been taken into the King’s hands on the grounds that Carminowe and his co-feoffees had failed to procure a royal licence for its acquisition, and custody was that month granted to two close associates of Bonville’s, Walter, Lord Hungerford† and Sir Philip Courtenay* of Powderham. By the summer, Bonville was suing Carminowe in the court of common pleas, claiming the immense sum of 2,000 marks in damages for his attempted fraud. In the autumn, the two men reached a settlement. On 27 Nov. Carminowe sealed a quitclaim of his right in the manor to Bonville, a document witnessed by the chancellor, Bishop Stafford of Bath and Wells, and three senior lawyers destined for the judiciary, Richard Newton, John Hody* and John Fortescue*, most probably the men who had arbitrated the dispute.
Relations between Carminowe and Bonville nevertheless remained strained. In mid 1439 Bonville sued him and Joan, the widow of his younger brother Walter Carminowe, for the abduction of Annora, daughter and heiress of John Trevanion*, Joan’s first husband, whose wardship Sir William claimed.
Although Carminowe was a notable Devon landholder, his interests and career were chiefly focused on Cornwall. This absenteeism from his landholdings further east may go some way to explain the repeated incursions into Carminowe’s property at Luffincott that he brought before the law courts from the 1430s.
If the Exeter authorities had sought to make an influential friend, their gift was wasted, for Carminowe died on 19 Dec. of the same year.
