[2] During the English Civil War Shrewsbury was a Royalist garrison and Prince Rupert stayed at Jones's house.
Jones was taken prisoner when the town was captured by the Parliamentarians in February 1645, the commissioners for corporations later stated that "he had declared himself against the commission of array" and "refused to find a dragoon for the King’s service".
In 1678, as one of the Popish plot judges, he drove hard for the conviction of Edward Coleman, but later clearly indicated his belief in Samuel Pepys' innocence.
In 1681 and 1683 he helped try the conspirators in the Popish Plot, and appears to have initially believed Titus Oates and other informers before changing his mind.
[3] Jones was the judge in the 1683 Quo warranto trial against the Corporation of London, and was rewarded on 29 September 1683 by succeeding Francis Pemberton as Chief Justice of the Common Pleas.
