The Rice (Rhys) family, who traced their descent from the Lord Rhys of Deheubarth, relied heavily on traditional loyalties and the evocative name of Dynevor to preserve their status as the first family and leaders of the Red or Tory party in Carmarthenshire. Rice’s father (then known as De Cardonnel) had had to relinquish the county seat in 1793 on succeeding his mother in the peerage; but, by giving his interest to the Williamses of Edwinsford and subsequently Sir Robert Seymour† of Taliaris, he tried to keep it available for Rice at the first election after he came of age.
Rice’s father and grandfather had fostered the West Wales Reds’ preference for reform rather than abolition of the Welsh courts of great sessions, and he was naturally named to the select committees on the issue, 2 June 1820, 21 Feb. 1821; it was the only one on which he made a major Commons speech before 1833. He divided with the Liverpool ministry against economies in revenue collection, 4 July, and could usually be relied on to vote with them in the 1820 Parliament, but some doubt remains concerning pro-retrenchment votes attributed to him on the estimates, 16 Feb., 15 Mar., 30 Apr. 1821.
he should continue to vote as hitherto upon measures as they came before the House. He did not conceive that he or any Member was called upon to pledge himself to a particular line of conduct during the session. The present was not the usual and regular mode of extracting information; and if ... [Hume] brought forward any motion of economy, he should, as before, exercise his discretion as to its fitness or otherwise.
The Times, 18 Feb. 1823.
He voted against reform, 20 Feb. 1823. He presented petitions from Carmarthen for repeal of the coal duties, 23 Apr., and Carmarthenshire against the window tax, 11 May 1824.
Now you must make up your mind to know me by another name too for I am to be Trevor for the future; that is, when the king shall give me leave. I have been changing my name often enough for one of my age. I was first De Cardonnel, then Rice and shall be Trevor ... I am to take the Trevor arms also.

As Rice Trevor, he voted to outlaw the Catholic Association, 25 Feb., and presented his constituents’ petitions against Catholic claims, 24 Apr., and corn law revision, 4 May 1825. He was named as one of those who had been unable to hear the question put before the division on the Southwark paving bill, 15 Apr.
He divided against Catholic relief, 6 Mar., and, having served on an election committee, was granted a month’s leave on urgent business, 23 Mar. 1827. His constituents petitioned strongly for repeal of the Test Acts and he may have brought up a favourable petition, 17 Feb., but he did not vote on the issue when it was opposed by the duke of Wellington’s new ministry, 26 Feb. 1828. As urged by John Johnes of Dolaucothi, he introduced, 21 Feb., and did all he could to secure the passage of the Carmarthen roads bill.
Rice Trevor disagreed with the government’s decision to concede Catholic emancipation in 1829 and felt obliged to explain his attitude. Bringing up a series of hostile petitions from Carmarthenshire, 9 Feb., he declared that he was
ignorant of the nature of the measure which it is intended to submit to the House, and can therefore have no distinct notion of what securities may be proposed for the Protestant church establishment. If ... I should find that those securities are not sufficient to satisfy my mind, my vote shall be what it always has been on this subject.
Later that month the patronage secretary Planta predicted that he would vote ‘with ministers’ for emancipation; but he presented further unfavourable petitions, 27 Feb., 3, 10, 12, 16, 20, 30 Mar., and divided 6, 18, 30 Mar., and paired, 23, 27 Mar., against the measure. The fate of its courts and judicature had become a major political issue in West Wales following publication in April 1829 of a law commission’s report advocating their abolition and redesigning the Welsh circuits.
He voted with the Ultras to condemn the omission of distress from the king’s speech, 4 Feb., but divided against Lord Blandford’s parliamentary reform scheme, 18 Feb., and paired against enfranchising Birmingham, Leeds and Manchester, 23 Feb. 1830. He had a vested interest in the deliberations of the select committee on the coal trade in London and the south-east, to which he was appointed, 11 Mar. On the 18th he presented a private petition against the Breconshire roads bill. When the miscellaneous estimates were considered, 10 May, he spoke of the need for better communications with southern Ireland, despite greater expense. He voted against Jewish emancipation, 17 May, and amending the Galway franchise bill, 24 May, when he presented a petition from Stowe against the sale of beer bill.
The ministry listed Rice Trevor among their ‘friends’, and he spoke briefly on their behalf on the address, 3 Nov., and divided with them on the civil list when they were brought down, 15 Nov. 1830. He echoed Hobhouse’s plea for better provision for the insane, 16 Dec., joined its presenter Lord James Crichton Stuart in endorsing Neath’s petition for repeal of the coastwise coal duties, 17 Dec. 1830, and brought up another against West Indian slavery, 7 Mar. 1831. Aware that his views on reform were increasingly at variance with those of his constituents, he stayed away from county meetings, and presented but declined ‘from a conscientious feeling of public duty’ to endorse Carmarthenshire grand jury’s petition for reform, 11 Mar.
Dynevor continued to oppose reform in the House of Lords, and the Carmarthenshire Whigs criticized Rice Trevor for joining the ‘Conservative Oak Reform Club at Gloucester in 1831 with Beaufort and other sinecurists’.
