Sneyd had succeeded his father as a vintner specializing in clarets, and in 1829 Robert Peel, the home secretary, wrote that ‘his house in the wine trade was the first in Dublin when I was in Ireland [in the 1810s] and ... I continued to have my wine from Mr. Sneyd after I left’.
Sneyd divided against censuring ministers’ conduct towards Queen Caroline, 6 Feb., and with them against repeal of the additional malt duty, 3 Apr., disqualifying civil officers of the ordnance from voting in parliamentary elections, 12 Apr., and Russell’s reform motion, 9 May 1821. He voted against inquiries into Irish tithes, 19 June, and the lord advocate’s treatment of the press in Scotland, 25 June 1822, but for one into the legal proceedings against the Dublin Orange rioters, 22 Apr. 1823. He was listed in the ministerial majority against repeal of the Foreign Enlistment Act, 16 Apr. 1823, but was an absentee the following year. In June 1824 he admitted to Peel that ‘I have been a truant this session, and have not laid eyes on St. Stephen’s’, to which he received the uncharacteristically warm reply: ‘I shall be most happy to see you again, and quite as much from the satisfaction it will give me to shake by the hand an old friend, as from the additional vote which your presence will ensure’.
By May 1824 it had become known that Sneyd’s unopposed return in 1820 had been on the understanding that he would make way for, and give his support to, an advanced Whig at the following election. This angered the Orangeman Lord Farnham, whose nephew Henry Maxwell occupied the other seat, as it threatened to open the county to an emancipationist.
The senior partner in the firm of Sneyd, French and Barton, he was returning from the Bank of Ireland to his premises in Upper Sackville Street on 29 July 1833, when he was knocked to the ground by the force of a gunshot, which grazed his temple. His assailant, one John Mason, was described as having ‘gazed on his victim for a few seconds and then, placing the pistol, which was four-barrelled, close to his forehead, he discharged the contents of one of the barrels into the head of Mr. Sneyd’. He apparently shouted ‘Oh! I have done for you’, as he ran off. Sneyd died speechless, after two days of excruciating agony, on the 31st. Mason, who was found to be deranged, could give no account of his actions save to insist that he had an unspecified grudge against the three partners, the death of any of whom would have pleased him equally well. Sneyd’s estate was presumably divided among his relations, who attended his funeral on 5 Aug. 1833 in St. Mary’s, Dublin, where it was intended to raise a monument in his memory.
