John Basset (1462–1528)

Sir John Basset KB (1462–31 January 1528), of Tehidy in Cornwall and of Umberleigh in Devon was Sheriff of Cornwall in 1497, 1517 and 1522 and Sheriff of Devon in 1524. Although himself an important figure in the West Country gentry, he is chiefly remembered for his connection with the life of his second wife and widow Honor Grenville (d. 1566), who moved into the highest society when she remarried to Arthur Plantagenet, 1st Viscount Lisle KG (d. 1542), an illegitimate son of King Edward IV, and an important figure at the court of King Henry VIII, his nephew.

The survival of the Lisle Letters, a large collection of letters to Lisle and his wife Honor, makes their lives two of the best-documented of the period. Honor retained for life as her widow's dower several Basset estates including Umberleigh and Tehidy, and the Lisle Letters include a great deal of correspondence to Honor from her stewards concerning their detailed management. They also include much correspondence to her from her children by Sir John Basset.
