The Trelawnys were an ancient Cornish family with parliamentary traditions reaching back to the reign of Edward II, and took their name from the family seat in the parish of Altarnon. The family’s unfortunate lack of imagination in naming their male offspring meant that at any given time in the fifteenth century there were usually at least three John Trelawnys active in the south-west, and it is not always possible to separate their careers. The first of the John Trelawnys, the subject of this biography, was born at some point between 1361 and 1365, for he was still a minor in 1382 but had come of age by 1386, when he was legally able to sell a tenement in Launceston to the local priory.
Both of Trelawny’s parents were dead by March 1377, when, as his guardian, Sir Ralph Carminowe† presented to the church of Menheniot, a property which had belonged to John’s maternal uncle.
It is not clear how Trelawny came to represent the borough of Bodmin in the dramatic Parliament of September 1397 (in which his old associate Roger Menwenick sat for Launceston), but he was by this date well connected within his native county. At the Launceston assizes in March 1389 (when he himself – probably on account of his attack on Stafford – was bound over in 500 marks) he had found surety of the peace for the influential Nicholas Broomford†;
In spite of his Membership of the Parliament of 1397-8, Trelawny did not embark on a career of office holding until after Henry IV’s accession, and even then appointments to Crown office remained few and far between. In the autumn of 1400 he was commissioned to inquire into acts of piracy off the Cornish coast, and five years later he was among those ordered to array armed men in the county. He attended the county elections at Launceston in October 1411 (the year when his eldest son, Richard, was returned by that borough), and set his seal to the sheriff’s indenture. He himself did not sit in the Commons again until the first Parliament of Henry V’s reign. The young King drew much of his administration from the ranks of those who had previously served him as prince of Wales and duke of Cornwall, and it is possible that he had come into contact with Trelawny in the context of the south-western duchy. By the end of 1414 John was serving as one of the three county coroners, and he was probably chosen immediately after the new King’s accession. It was the coroners’ duty to attend the county court, and there is little doubt that Trelawny attested the Cornish shire elections of November 1414 and February 1416 in his official capacity.
In the summer of 1415 Trelawny set out to fight in France in the retinue of Edward, Lord Courtenay, heir to the earldom of Devon, and probably fought at Agincourt alongside him. It is likely that he owed the knighthood which had been bestowed on him by 1417 to his exploits on this occasion. Later family tradition had it that the grateful King had permitted Trelawny to augment his armorial bearings by three oak or laurel leaves in recognition of his valour during the expedition.
Sir John returned to England in time to seek election to the first Parliament of 1421, and he had good cause to do so. During his absence, his distant cousin Robert Trewythenick had died without offspring, leaving Trelawny as next heir to the family property. On his return, he laid claim to the lands, but met with a stiff challenge from the grasping Sir Ralph Botreaux*, and was left with no alternative but to petition Parliament for a special assize.
Within the borough of Launceston, not far from his residence at Altarnon, Trelawny was well respected. In November 1414 he had been called upon to witness a grant by the local authorities for the foundation of St. John’s chapel,
In December 1421 Trelawny had been elected to the Commons for the final time, and on that occasion was accompanied to Westminster by his younger son, John, who had been chosen one of the burgesses for Liskeard. Interestingly, he was not entrusted with his county’s representation in the first Parliament of the young Henry VI’s reign, but was nevertheless present at the parliamentary elections, and sealed the sheriff’s indenture. Despite his absence from the Commons, Trelawny rapidly secured confirmation of his valuable annuity, which – in spite of the chronic financial difficulties of the young King’s administration – continued to be paid until the end of his life.
