Sir Francis Bassett (1594 – 1645) of Tehidy in the parish of Illogan in Cornwall, was Sheriff of Cornwall and a Vice-Admiral of Cornwall, a Member of Parliament for St. Ives and Recorder of St Ives. His portrait by Vandyck was formerly displayed at Tehidy (now demolished). He appears to have been a sportsman, much addicted to hawking and cock-fighting.
During the Civil War in 1643 he acted as a Royalist in the western part of Cornwall, raising money and drilling forces for the king. Letters of his to his wife ‘at her Tehidy’ are preserved, recording the Royalist victories of Stamford Hill near Stratton, and of Braddock Down near Lostwithiel, at the latter of which (or at any rate very shortly after the fight) he, with most of the Cornish gentry, was present, and was knighted on the field. He records in another letter to his wife that after the battle ‘the king, in the hearing of thousands, as soon as he saw me in the morning, cryed to mee “Deare Mr. Sheriffe, I leave Cornwall to you safe and sound”’.
He was High Sheriff of Cornwall in 1642–1644; there is a complaint against him in the Star Chamber, 18 May 1625.
In 1640 he presented to the borough of St Ives a loving-cup bearing the following inscription:
In 1620 he married Ann Trelawny, a daughter of Sir Jonathan Trelawny (1568-1604) of Trelawny, Cornwall. Their children included John Basset, eldest son and heir and Francis Basset, second son, of Taunton, Somerset, a puritan who in 1661 was accused of a conspiracy against King Charles II, of which charge he was honourably acquitted after a letter which he was alleged to have written was proved a forgery.
Sir Francis died 19 September 1645. The full vengeance of Cromwell fell upon his son and heir John Basset, although he had never taken up arms, who was compelled to compound for his estates, and had to sell St Michael's Mount in 1660 to a member of the St Aubyn family, in whose possession it has remained ever since.
