Henry Neville took the name of Grey by private Act of Parliament in 1707 in accordance with his uncle’s will, under which he succeeded to estates charged with £40,000, the price of the 3rd Lord Grey’s pardon for his share in Monmouth’s rebellion. He was returned as a Whig at a contested by-election for Wallingford in 1719; stood unsuccessfully for Berkshire in 1722; and joined his elder brother, Grey Neville, as Member for Berwick in 1723. Early in 1726, when ‘the interest upon the £40,000 amounted to £12,000, ... the mortgagees foreclosed and entered on his estate’, although ‘he had coming in £9,700 per annum, in as good rents as in England’. On 18 Feb. Grey
charged his pistols in the morning, taking them with him ... he sent a letter to his wife and another to Sir Robert Walpole, dated from a tavern, I think in Drury Lane: he told his wife that she would see him no more and Sir Robert, that he desired he would dispose of his borough ... since then search has been made for him but to no purpose.
Ten days later Grey
has since been heard of from Calais and ... intends to return when he can reconcile himself to the looking his friends again in the face. Peter Walter proposes to put him in a method of paying his debt and to allow him £2,000 a year out of his estate to live upon, everything else of Grey’s to be sold to pay his debts.1HMC Portland, vii. 426; Dr. Geo. Clarke to Edw Nicholas, 19 Feb. and 1 Mar. 1726, Egerton mss 2540, ff. 588-9, 596-7.
In November 1732 he was among several parliamentary candidates considered by the Berwick corporation ‘for a third man, to make some sport as they call it’.2Geo. Liddell to Sir Robt. Walpole, 24 Nov. 1732, Cholmondeley (Houghton) mss. Successful in 1734 for Reading, he voted with the Government till his death, 9 Sept. 1740.
