Sir Thomas Jervoise (11 June 1587 – 20 October 1654) was an English politician who sat in the House of Commons variously between 1621 and 1653.
He was a staunch supporter of the Parliamentary side during the English Civil War.
On the outbreak of the Civil War Jervoise was Colonel of one of the regiments of Hampshire Trained Bands and four companies of his regiment served alongside Sir William Waller's Parliamentarian Southern Association Army at the Siege of Portsmouth.
[6] In July 1601, aged 14, Jervoise married Lucy Powlet, daughter of Sir Richard Powlet of Herriard and Freefolk, Hampshire, and thereby acquired the Herriard estate and influence in Hampshire, to add to his family's substantial estates in Wiltshire, Worcestershire and Shropshire.
[4] Lucy died in 1641, and within two years Jervoise married Frances, daughter of Thomas Jay of Foscott, Buckinghamshire.
