Among the concerns that moved the great Sir John Arundell I of Lanherne for much of his life was the adequate provision for his younger sons. Renfrew was the youngest of these and was first given estates of his own in 1421, following his marriage to Joan Colshull. The lands that Sir John granted to him on this occasion included the Cornish manors of Treloy (in St. Columb Minor) and Trink (in Lelant).
More problematic, it seems, was Arundell’s title to the manor of Lanivet, which he claimed to have acquired from Benedict Gyffard. In the autumn of 1431 Gyffard’s cousin John Bounteth along with his aunt Alice and her husband, Roger Prideaux of Penvose, staked their claim to the property, and the dispute continued until Arundell’s death, by which time Prideaux had died and Bounteth had been replaced by Otto Nicoll* of Penvose and his wife Joan among the claimants.
Although given a degree of independence from their father by the estates he had settled on them, the younger Arundells maintained close connexions with Sir John, and Renfrew was no exception. Thus, when in 1428 Sir John embarked on the great charitable enterprise of his life and founded a chantry at St. Columb Major that was to become the richest such establishment in Cornwall in the fifteenth century, Sir Thomas and his descendants were made the principal trustees of the endowment, with remainder in default of issue to Renfrew and his heirs.
Ever since Henry IV had usurped the throne, the Arundells had maintained close links with the Lancastrian dynasty. Whereas his father and eldest brother entered the service of the new duke of Cornwall, Prince Henry (afterwards Henry V), Renfrew became part of the affinity of Henry IV’s half-brother, Henry Beaufort, bishop of Winchester and cardinal of England. It is uncertain when he first formed this association with Beaufort, but he may already have done so when he was elected to his first Parliament in 1431.
Not long before the English delegation to Arras sailed for France, Arundell’s father had died, leaving as his heir his under-age grandson. It now fell to the young John Arundell’s uncles to maintain the family’s customary position in local society, and, along with his brothers, Renfrew began to play his part in county administration. Knighted during the course of 1436, he was pricked sheriff of Cornwall in the autumn of 1437. After he was added to the Cornish bench a year later, he energetically set about his duties in keeping the peace.
Arundell’s connexions at court did not prevent him from otherwise leading the life of an ordinary west-country gentleman. He may occasionally be found attesting deeds for his kinsmen and neighbours,
Closely connected with the court, Arundell secured election to the Commons for a third time in January 1442. He was not to see this assembly dissolved, for he died within less than two weeks of its opening.
