Little is known of Lawrence Fiennes prior to his accession to the peerage in 1710, which came about as a result of the failure of the senior branch of the family represented by Nathaniel Fiennes, 4th Viscount Saye and Sele. It has not been possible to determine a precise date for Fiennes’ birth (or that of his father, who probably died in about 1692).
It was no doubt as a result of his obscure heritage that Fiennes’s succession to the peerage did not go unquestioned. Narcissus Luttrell described his title as ‘somewhat dubious’ and in February 1710 Saye and Sele was forced to petition the queen for a writ of summons.
Saye and Sele attended four of the prorogation days between April and July 1710. On 3 Oct. Robert Harley, later earl of Oxford, assessed him as a likely supporter of his new ministry. He resumed his seat at the opening of the new Parliament on 27 Nov. 1710, after which he was present for three-quarters of all sitting days in the first session. On 5 Feb. 1711 he registered his dissent at the resolution to reject the general naturalization bill and in June he was included in a list of Tory patriots. Resuming his seat at the opening of the second session on 7 Dec., after which he again attended approximately three-quarters of all sitting days, on 19 Dec. he was correctly forecast as being in favour of allowing James Hamilton, 4th duke of Hamilton [S], to take his seat in the House as duke of Brandon and voted accordingly the following day.
Deprived of the inheritance of both Broughton and his father’s estate at Great Amwell in Hertfordshire (which had passed to his brother-in-law, Thomas Filmer), Saye and Sele’s name was included in a list of ‘poor lords’ to be sent to the future George I on 15 Jan. 1712.
Saye and Sele returned to the House at the opening of the new Parliament on 16 Feb. 1714, after which he was present on almost 89 per cent of all sitting days in the first session. On 27 May, Daniel Finch, 2nd earl of Nottingham, forecast that Saye and Sele would be a supporter of the schism bill. He resumed his seat on 3 Aug. and attended eight days of the brief 15-day session that met in the wake of the queen’s death.
Saye and Sele continued to attend the House frequently under the new regime. In February 1718 he accepted the government pension that secured his support for Sunderland’s ministry, though it was noted that he ‘would not vote against the earl of Oxford in any critical matter’.
Saye and Sele died unmarried on 27 Dec. 1742. In his will he named his kinsmen Edward Trotman and Robert Eddowes as executors. The peerage and the greater part of Saye and Sele’s possessions, including his coronet and both coronation and Parliament robes, passed to his cousin Richard Fiennes* [1142], at the time a fellow of New College, Oxford, who succeeded as 6th Viscount Saye and Sele.
