Thomas John, the elder of two sons born to the 1st Lord Newborough and his Florentine child bride, was not conceived until his half-brother John, the only child of his father’s marriage to Lady Catherine Perceval, had died without issue. The family’s fortunes had declined and they had lost the Caernarvonshire seat in 1774, the county lieutenancy in 1781 and Caernarvon Boroughs in 1790 to the Bulkeleys of Baron Hill and the Pagets of Plas Newydd.
From my experience of ... [Newborough’s] opinions and disposition, I cannot but think the most beneficial plan which can be adopted for his future education would be either to send him immediately to Christ Church if possible (and perhaps a single admission for a nobleman might be obtained) or adopt some line of proceeding by which he may be entitled to see more of the world, and thus learn to conform to the practices of society in general.

He was sent to the continent for a year with the Rev. William Phillips, who became his Oxford tutor. The trustees, whom his mother threatened with prosecution, expended £29,650 during his minority and made several applications to chancery for additional funds.
Bulkeley had died in 1822 and his successor as lord lieutenant, Thomas Assheton Smith I* of Vaenol, encouraged Newborough to oppose the return of Bulkeley’s pro-Catholic half-brother Sir Robert Williams for Caernarvonshire at the first opportunity. Disappointed at the failure of the Ffestiniog railway bill and shortcomings in the 1825 Caernarvon-Llanllyfin Railway Act, he announced his candidature when a dissolution was anticipated that September. He denied making any pledge not to oppose Williams and raised the ‘No Popery’ cry. Williams was outraged that after ‘living on the most friendly terms with all my family’, he should behave thus.
By the time he took his seat in November, his agents and supporters had made the necessary local preparations for bills to fund the Nantlle Railway Company and enclose Landwrog and Llanwnda to further Glynllifon’s agricultural and quarrying interests. Petitions for both bills were presented, 24 Nov. 1826, and Newborough was given leave to bring them in.
whatever measures ... ministers may think proper to bring before this House, for securing the peace and happiness of Ireland, for remedying the dreadful evils that now exist - and above all for healing the religious animosities between Catholic and Protestant - I shall give my most cordial support, provided they are accompanied by those solid securities which are likely to tranquillize the just fears of His Majesty’s Protestant subjects. Without those safeguards ... I consider it would be an extravagant extension of confidence to yield anything like unconditional submission to their claims. Should such be attempted by ... ministers, which I am sure they will not do, I shall conceive it my duty to give my most determined opposition to the measure.
The paper’s editor remained dissatisfied.
A slight improvement in his condition enabled him to return and campaign actively for repeal of the slate duties in 1831. Presiding at the county meeting, 15 Jan., he condemned that tax which ‘prevents the flow of capital, fetters the spirit of enterprise, and creates distress and dissatisfaction among the industrious and labouring classes of the community’. He also promised ‘to come forward with my heart, as well as my purse, to promote every cause which has for its object the welfare of the town and the county of Caernarvon’.
Glynllifon’s influence in the Boroughs increased under the Reform Act, but neither Newborough nor his brother agreed to stand for Parliament, and by September 1832 both had declared their support for the Tory candidates in the Boroughs and county.
