Kendale was a scion of a Cornish family with long traditions of service, both to the Crown and in Parliament. Much of the Kendales’ wealth was derived from the Cornish tin industry, although it was not always gained by savoury methods: in early 1390 Sir Richard Cergeaux† claimed that a group of men, including Kendale, had diverted the water supply from one of his mines, called ‘Tye’, to serve their own tinworks, wasting 5,000 pounds of tin worth 50 marks.
The Kendales had long been among the leading gentry of Cornwall, so there was nothing unusual in Thomas’s attendance at the Cornish shire elections in 1426 alongside his brother Stephen. The latter, who took a more regular interest in parliamentary affairs, again attested the indenture recording the names of the knights of the shire and the burgesses elected in the following year, when Thomas was himself returned by the townsmen of Lostwithiel. Although Thomas is not known to have held borough office, he occasionally witnessed deeds for his neighbours, and it is probable that alongside his family’s standing such local credentials played a part in securing his return.
In 1431 Kendale quarreled with the influential landowner Sir John Trelawny†, but no details of their disagreement have come to light.
