In April 1695 the crown granted Ralph Grey a lease of five lighthouses in Winton Ness (Winterton Ness) and Orford Ness in Norfolk, with an estimated income of £1,200 p.a., for £20 annual rent and an entry fine of £750 ‘only and in consideration of the said Grey’s good services’.
Tankerville was appointed a commissioner of the board of trade in May 1696, and in this position was able to acquire for Ralph the governorship of Barbados and the Windward Islands in July 1697.
Despite his absence in the West Indies, Grey was returned once more for Berwick in the first election of 1701. He did not attend, but his elder brother died on 24 June 1701, the very day on which that Parliament was prorogued. Tankerville had no male heirs, so while the earldom did not pass to his younger brother, Ralph did inherit their grandfather’s title of Grey of Warke. The new 4th Baron Grey of Warke was still marked as ‘abroad’ at a call of the House on 5 Jan. 1702, but had arrived home in time to take his seat on 22 January. After this late arrival he sat in a further 35 sittings of that Parliament, which saw the death of his patron William III and the accession of Anne.
In the early days of the new reign, John Macky described the new baron (mistakenly named Ford Grey in the printed edition of the Memoirs), as: ‘A sweet disposed gentleman. He joined King William at the Revolution, and is a zealous asserter of the liberties of the people – a thin, brown, handsome man, middle stature’. Jonathan Swift, though, appended to this character sketch the comment, ‘Had very little in him’.
On the same day as this important vote, Grey of Warke petitioned the House to bring in a bill which sought to confirm complicated arrangements he had made with both Rochester and his own nephew Charles Bennet, 2nd Baron Ossulston (married to Tankerville’s daughter), regarding the disposition of the encumbered Grey estates. The bill was read for the first time on 21 Dec. 1703 and passed the House on 14 Jan. 1704, before receiving the royal assent on 24 February. By this act Grey of Warke agreed to compound with both Ossulston and Rochester for £15,000 each to discharge various debts and free up the encumbered estates.
During his brief career in the House, Grey of Warke occasionally chaired committees. At the latter part of the 1704–5 session (during which he was present for 79 per cent of the sitting days), he chaired and reported from a committee of the whole considering the recruiting bill on 2 Mar. 1705. He also chaired select committees on three separate estate bills and on 16 Mar. reported to the House from one of these, the bill for John Proctor of Northumberland to sell part of his estate, for which Grey’s northern connections and knowledge may have been called upon.
He was registered as the holder of the proxy of the Whig Charles Cornwallis, 4th Baron Cornwallis, on 14 Mar. 1705, but had no opportunity to use it as Parliament was prorogued that very day and then dissolved barely a month later. He was marked as a Hanoverian in a list analysing the attitudes of the peerage towards the succession that appeared shortly after the dissolution. During the first session of the 1705 Parliament, for which he was present at just over three-quarters of the sittings, Grey continued to be active in the proceedings of the House, and was named manager for a number of conferences in February and March 1706: for the Regency bill (7, 11 and 19 Feb.); for the consideration of the printed letter of Sir Rowland Gwynne‡ to Thomas Grey, 2nd earl of Stamford (11 Mar.), and for the militia bill (13 March).
Grey of Warke died suddenly of apoplexy on 20 June 1706. By the provisions of a settlement drawn up by his grandfather in 1672 the Epping estate passed to his cousin, the Tory William North, 6th Baron North.
