The Barnardistons were an ancient family that had held the manor situated in west Suffolk from which they took their name since at least the reign of Richard I. A Peter de Denardeston or Barnardiston represented Suffolk in 1298. Subsequently Sir Thomas Barnardiston acquired additional estates in Lincolnshire, which he represented in 1358, and the manor of Kedington, adjacent to Barnardiston, which became the family seat.
Barnardiston’s grandfather Thomas, said to have been educated in Geneva during the Marian persecution, raised the family to its greatest affluence.
Barnardiston’s father died in his grandfather’s lifetime, and consequently it was from the latter that Barnardiston inherited the family estates in 1619. There is no evidence that he sought election to the third Jacobean Parliament, and in 1624 he was ineligible as sheriff of his county, but in the following year he was elected for Sudbury, about 11 miles from Kedington. He made no recorded speeches in the first Caroline Parliament, but was named to the committees for the bills to prevent tippling (24 June) and to mitigate excommunication (27 June) and, after the session had been adjourned to Oxford, for a naturalization bill (11 August).
In January 1626 John Winthrop, writing to Sir Robert Crane, suggested Barnardiston as a possible candidate for the county, ‘though he be out of the country’, if Crane did not want to stand himself.
Appointed a commissioner for the Forced Loan, Barnardiston (according to Winthrop) arrived late for the inaugural meeting for executing the Loan in Suffolk on 16 Dec. 1626.
Released from confinement in January 1628, Barnardiston was returned for the county to the third Caroline Parliament unopposed, though there was little enthusiasm for the election.
Barnardiston was again returned for Suffolk at both elections in 1640. As a strong parliamentarian and a Presbyterian elder he was the dominant figure in Civil War Suffolk; but he abstained from the House after Pride’s Purge.
