Sir Thomas Davies Lloyd, 1st Baronet (21 May 1820 – 21 July 1877) was a British Liberal Member of Parliament, for Cardiganshire (Ceredigion) 1865–1868 and Cardigan Boroughs 1868–1874.

Upon the death of his father in 1845, Lloyd returned to Wales, and on 21 January 1846 he married Henrietta Mary, fourth daughter of George Reid, Esquire, of Watlington Hall, Norfolk, and Jamaica.

He inherited the title of 24th Marcher Lord of Cemaes, which gave him authority to hold a Court Leet and other ceremonial occasions such as beating the bounds at Newport, Pembrokeshire.

Throughout the 1850s, Lloyd was frequently named as a potential candidate for election to the House of Commons, either to represent Cardigan Boroughs or the more prestigious Cardiganshire county constituency.

Subsequently, a requisition was presented to Lloyd to contest the county seat in opposition to the Earl of Lisburne, and even at a late stage he was expected to go to the poll and is to have a chance of success.

The Aberdare-based Gwladgarwr, for example, deprecated the fact that two Conservatives, namely Colonel Powell of Nanteos and Arthur Saunders-Davies, were contesting Cardiganshire.

Lloyd, meanwhile, became involved in Pembrokeshire county politics, proposing Sir Hugh Owen of Orielton as Liberal candidate at the by-election held in January 1861.

[12] Owen, like Lloyd was in favour of "a slow and safe reform" rather than more radical politics, but was defeated at the election by the Conservative candidate, George Lort Phillips.

[n 1] Prior to the 1865 General Election, Colonel Powell, the sitting member for the Cardiganshire county constituency had indicated his intention to retire.

However, Lloyd was supported by those landowners who were associated with the Whig tradition, including Pryse family of Gogerddan who heavily influenced the politics of Aberystwyth.

[19] After the election, Davies made significant contributions to chapels in the north of the county where Lloyd had won by a small margin.

[21] He was however prepared to transfer to the borough seat in the event that the sitting member, Colonel Edward Pryse, decided to retire.

[22] A few weeks earlier, a Liberal meeting at Aberaeron offered him the opportunity of contesting the county again but at the same time the sitting member for Cardigan Boroughs, Edward Pryse, was obliged to step down to allow Lloyd to be returned for that constituency.
