last summons to council on his return to Whitehall on 16 Dec.
As an equity judge Trevor was a conspicuous success, and he continued in the most exemplary manner to dispense justice at the rolls court until the accession of William III, when he was displaced.
To the convention parliament he was returned for Beeralston, Devonshire, on 21 May 1689, and to the following parliament for Yarmouth, Isle of Wight, on 4 March 1689–1690. On the meeting of the latter parliament he was again chosen speaker (20 March), and on 1 Jan. 1690–1 he was sworn of the privy council. He was also chief commissioner of the great seal in the interval (14 May 1690 to 23 March 1692–3) between its surrender by Sir John Maynard (1602–1690) [q. v.] and its delivery to Lord-keeper Somers [see Somers or Sommers, John, Lord Somers]. On 13 Jan. 1692–3 he was reinstated in the mastership of the rolls. He continued to hold the speakership until, being detected in the acceptance of 1,100l. from the common council of London for promoting the orphans bill, he was voted guilty of a high crime and misdemeanour (12 March 1694–5). This resolution he himself put from the chair on the report of a committee by which he was incriminated (Add. MS. 17677 PP. f. 192 b). On the following day he absented himself from the house, sending the mace with a letter alleging that a fit of colic prevented his attendance. As his indisposition continued, the house, with the king's leave, elected Paul Foley [q. v.] speaker in his room. On 16 March Trevor was expelled the house; nor was he re-elected. He was not, however, deprived of the mastership of the rolls, which he continued to hold until his death.
On the accession of Queen Anne, Trevor recovered credit. He was sworn of the privy council on 18 June 1702, and in April 1705 was appointed constable of Flint Castle. He was also custos rotulorum of Flint.
Trevor had ‘a pretty seat’ near Pulford, Denbighshire (Diary of Dean Davies, Camden Soc. p. 110). His town house was in Clement's Lane, where he died on 20 May 1717, leaving personalty to the amount of 60,000l. His remains were interred in the Rolls chapel.
By his wife, Jane (d. 1704), daughter of Sir Roger Mostyn, bart., of Mostyn, Flint, relict of Roger Puliston of Emerall in the same county, Trevor had issue four sons and a daughter. The sons died without issue. The daughter, Anne, married, first, Michael Hill of Hillsborough, Ireland; secondly, Alan Brodrick, viscount Midleton [q. v.] By her first husband she was mother of: (1) Trevor Hill, who was created on 21 Aug. 1717 Viscount Hillsborough in the peerage of Ireland, and was father of Wills Hill, first marquis of Downshire [q. v.]; (2) Arthur Hill, who assumed the additional surname Trevor, was created on 17 Feb. 1766 Viscount Dungannon in the peerage of Ireland, and was great-grandfather of Arthur Hill-Trevor, third viscount Dungannon [q. v.]
Trevor was a lawyer of no small learning and ability, and apparently as upright on the bench as he was unscrupulous in the House of Commons (Burnet, Own Time, fol. edit. ii. 42). He squinted, and, though fond of his bottle, was otherwise as penurious as avaricious. His ecclesiastical views may be inferred from the fact that he regarded Tillotson as a fanatic. A portrait in oils by J. Allen is at Brynkinalt. An engraved portrait is at Lincoln's Inn.
A paper by Trevor on the state of factions on the eve of the dissolution of William III's first parliament is printed in Dalrymple's ‘Memoirs’ (App. ii. 80). His decisions are reported by Vernon, Peere Williams, and Gilbert.
