Hort’s father, second son of the archbishop of Tuam, 1741-51, had been appointed consul-general at Lisbon in 1767 and created a baronet the same year. On the death in 1786 of his elder brother Josiah George, Kildare’s sheriff in 1758, he had acquired the ‘fine estate’ of Hortland, which Hort inherited on succeeding to the baronetcy in 1807, when he became the ward of Lord Henry Petty† (later 3rd marquess of Lansdowne). On meeting Hort and his brother for the first time in Paris in September 1818, Maria Edgeworth described him as
a very pleasing young man ... [with] dark eyes, round good natured face, gentlemanlike figure, middle sized, good manners, no conceit, or ennui ... far above most of the young men of the present day. Literature enough for conversation, no pretension, a very good mechanic. At dinner one day Lord Grenville and all the gentlemen except himself were talking nonsense about the new magnetic perpetual motion. He modestly asked a question or two which showed he understood it was all nonsense and even the authority of Lord Grenville’s eye and contradictory belief could not frighten him ... We became acquainted and to a certain degree intimate from that time forward. He always sits where he ought to do at dinner.
Later that month, however, she noted that he ‘did not appear so agreeable when I saw more of him’, adding that he ‘was a good humoured young man and that was all. Nothing came out on further acquaintance’.
Hort voted for the second reading of the reintroduced English reform bill, 6 July, at least twice against adjournment, 12 July, and gave generally steady support to its details, although he divided for the enfranchisement of £50 tenants-at-will, 18 Aug. 1831. He voted for the third reading, 19 Sept., and passage of the bill, 21 Sept., and Lord Ebrington’s confidence motion, 10 Oct. On 30 July he joined Brooks’s, sponsored by Lords Duncannon* and Killeen*, an earlier membership of 21 May 1817, when the sponsors were Sir Henry Parnell* and Lord Essex, apparently having lapsed. In his maiden speech, 5 Aug., he defended the practices of Maynooth College and called for a liberal system of Irish education with grants distributed so that all religions ‘might derive an equal benefit’. On 11 Aug. he spoke and voted for printing the Waterford petition for disarming the Irish yeomanry, the ‘last persons who ought to be employed on anything approaching military service in time of peace’. He divided with ministers on the Dublin election controversy, 23 Aug., and voted for legal provision for the Irish poor, 29 Aug. He divided for the second reading of the revised reform bill, 17 Dec. 1831, again supported its details, and voted for the third reading, 22 Mar., but was absent from the division on the motion for an address calling on the king to appoint only ministers who would carry it unimpaired, 10 May 1832. He voted to print the Woollen Grange petition for the abolition of Irish tithes, 16 Feb., and against the Irish tithes bill, 8 Mar. On the 23rd he presented and endorsed petitions for their total abolition, saying that the time had ‘now come when the public must face the question’ of the Irish church and that as ‘a sincere Protestant’ he was ‘prepared to place all religious creeds on the same footing’. He divided for the second reading of the Irish reform bill, 25 May, but against the liability of Irish electors to pay municipal taxes before they could vote, 29 June. He was granted ten days’ leave on account of family illness, 19 June, but was credited with a vote for Baring’s bill to exclude insolvent debtors from Parliament, 27 June.
At the 1832 general election Hort came third in a contest against two other Liberals. He died in Eaton Square, London, in August 1876 and was succeeded by his eldest son John Josiah (1824-82), an army officer.
