during the negotiations at Newport. He afterwards suffered a term of imprisonment—cause and duration uncertain—which was intermitted in 1650 for three months, during which he had leave (license of the council of state dated 22 July) to reside in London for the benefit of his health. On 18 Dec. 1656 he was authorised to resume practice at the bar; but, scrupling to recognise the government, he remained in retirement until the Restoration.
Declining the seat on the bench then offered him by Clarendon, Vaughan was appointed about July 1660 steward of Mevennydd and other royal manors in Cardiganshire. Returned for that county to the pensionary parliament, he early distinguished himself as a leader of the country party. He was the principal opponent of the transference of the three years' limit from the duration to the intermission of parliaments (31 March 1664–5), and made an ingenious but unsuccessful attempt to enervate by amendment the new test imposed on dissenting ministers in the same year (Burnet, Own Time, fol. i. 225). In 1667 (October to December) he stood forth as one of the most zealous and determined of the promoters of the impeachment of his former friend Clarendon. He presided in the spring of 1668 over the committee charged with the collection of precedents bearing on the constitutional questions raised by the cases of Alexander Fitton [q. v.] and Thomas Skinner (1629?–1679) [q. v.], and took a leading part in the conferences with the lords and other proceedings. In the same year he was knighted, invested with the coif, and created chief justice of the common pleas (19–20 May). As such he was ex officio a member of the court of summary jurisdiction charged with the determination of cases between owners and occupiers of tenements in the districts ravaged by the fire of London (19 Car. II, c. 3). In recognition of his services in this capacity, the corporation caused his portrait to be painted by Michael Wright, and placed in Guildhall (1671). By virtue of a special commission Vaughan sat as speaker of the House of Lords in the absence of Lord-keeper Bridgeman, 6–18 Nov. 1669, and 11 March to 4 April 1669–70.
Vaughan died at Serjeants' Inn on 10 Dec. 1674. His remains were interred in the Temple church, where there is a monument to his memory. The portrait of Vaughan mentioned by Evelyn (Corresp. ed. Bray, p. 301) as in the Clarendon gallery is now missing. Engraved portraits of him are at the British Museum, and one is prefixed to his ‘Reports,’ edited from his manuscripts by his son, Edward Vaughan, London, 1677, fol.; 2nd ed. 1706. Three of Vaughan's letters, one dated 12 March 1643–4, the others only 10 and 11 April, are printed in ‘Archæologia Cambrensis,’ new series, iv. 62–7.
Edward Vaughan (d. 1688), son of the lord chief justice by his wife Jane, eldest daughter of John Stedman of Cilcennin, Cardiganshire, M.P. for Cardigan 26 Feb. 1678–9 to 28 March 1681, married Letitia, daughter of Sir William Hooker, and had a son John (b. about 1670, d. 1721), who was created by William III Baron of Fethard, co. Tipperary, and Viscount Lisburne, co. Antrim, and was ancestor of the Earls of Lisburne.

VAUGHAN, Sir JOHN (1748?–1795), lieutenant-general, born in 1747 or 1748, was a younger son of Wilmot Vaughan, third viscount Lisburne, by Elizabeth, eldest daughter of Thomas Watson of Berwick-on-Tweed. He entered the service in the old 52nd regiment, or Colonel Pawlett's 9th regiment of marines, from which on 9 April 1748 he was transferred to a cornetcy in the 10th dragoons. He became lieutenant in the regiment on 10 Dec. 1751, captain-lieutenant on 5 Jan. 1754, and captain on 28 Jan. 1755. With the 10th dragoons he served in England and Scotland, and in Germany during part of the seven years' war. He left the
