O’Grady, whose ancient Irish family had long been resident in county Limerick, was the son and namesake of a Dublin barrister of wit, diligence and superiority, who was called in 1787 and, having come to the attention of his neighbour Lord Clare, the Irish lord chancellor, became a king’s counsel ten years later. In early 1803 he was considered a possibility for the vacant Irish attorney-generalship and Clare’s successor Lord Redesdale wrote to Addington, the prime minister, that he, ‘five or six years hence, would be the man you would wish to place in the post, but [he] has not yet the years, the experience or the weight of character one would wish to find for such an office’. Nevertheless, and despite not being in Parliament, he was chosen and duly led the state prosecutions of Emmet and his fellow rebels that year. In 1805 he succeeded Viscount Avonmore as chief baron of the Irish exchequer and he held this senior judgeship for the following 25 years.
O’Grady attended Trinity College, Dublin, like his father, but entered the army and served in the last stages of the Napoleonic Wars. He distinguished himself leading the rear troop of the 7th Hussars in their retreat, under constant attack by French lancers, to Genappe, 17 June 1815, when he was warmly praised by his commanding officer Lord Uxbridge†, who was shortly to be created marquess of Anglesey. He fought at Waterloo the following day, afterwards writing to his father that ‘the 7th had an opportunity of showing what they could do if they got fair play. We charged 12 or 14 times, and once cut off a squadron of cuirassiers’.
He voted for Hume’s motion on the civil list, 3 May, against the appointment of an additional baron of exchequer in Scotland, 15 May, the aliens bill, 1 June, and for economies in revenue collection, 4 July 1820. The following day he wrote to Henry Grattan II* to explain that he had not hurried on the Dublin writ following his father’s death the previous month.
Perhaps because of the delicate position in which his father was placed by the continuing parliamentary inquiry into his conduct as a judge, O’Grady apparently showed a greater tendency to back ministers in the following two sessions. Speaking from experience, having been involved in attempts to suppress violent unrest in his county, he spoke at length for the Irish insurrection bill, 7 Feb. 1822, although he did hint that day that he would support conciliatory measures and on 4 Mar. he complained that two regiments had been disbanded at Limerick at the height of the disturbances. He divided against more extensive tax reductions to relieve distress, 11, 21 Feb., although he voted to reduce the number of junior lords of the admiralty, 1 Mar. He was named to the select committees on Irish grand jury presentments and Limerick taxation, 23 May. He backed the Irish tithes leasing bill, despite what he saw as its inadequacies, 13 June, but voted for inquiry into tithes on the 19th. The chief baron’s case was put off for that session, 4 July 1822, and it may have been over this that O’Grady apparently fought a duel with James Grattan* early that month.
Rice having again raised the allegations against the chief baron, 12 Feb., O’Grady was appointed on 19 Mar. to another select committee on this, which reported, 16 May 1823.
No evidence of parliamentary activity by O’Grady has been traced during the 1824 session. He voted for the Irish unlawful societies bill, 15, 25 Feb., and praised the zeal of Limerick magistrates in ending outrages there, 22 Feb. 1825.
His vote to suppress the Catholic Association and his failure to attend the Catholics’ provincial meeting in Limerick in October 1825 partly accounted for his unpopularity at the general election of 1826, when he offered on the basis of his parliamentary conduct and stressed that he supported Catholic relief, but was suspected of being ‘illiberal’. He trailed behind Fitzgibbon and Lloyd throughout the ensuing contest and protested that his defeat was caused by the aristocratic interests arrayed against him.
On the death of Lloyd in December 1829 O’Grady offered again as an independent for county Limerick, with the significant endorsement of O’Connell, and fought a severe contest against an aristocratic interloper from Tipperary, James Hewitt Massy Dawson*.
Perhaps sensing his electoral weakness, Massy Dawson eventually withdrew before the general election of 1830, so allowing O’Grady to be returned unopposed.
He voted for the second reading of the reintroduced reform bill, 6 July 1831, at least twice against adjourning proceedings on it on the 12th and steadily for its details. He divided for printing the Waterford petition for disarming the Irish yeomanry, 11 Aug., but for the Irish union of parishes bill, 19 Aug., and with government in both divisions on the Dublin election, 23 Aug. He objected to the new Irish lord lieutenants being given the power to appoint county clerks of the peace and urged the creation of an Irish commission of works, 15 Aug. He advocated the introduction of a system of poor laws to Ireland, but declined to support Sadler’s resolution on this as inadequate, 29 Aug. He voted for the passage of the reform bill, 21 Sept., and Lord Ebrington’s confidence motion, 10 Oct. Reckoned to be a liberal Member and a tolerably good speaker, his poor attendance record was criticized by the radical William Carpenter that year.
In August 1832 he wrote to one constituent that illness had kept him from the House, but that he hoped to present and endorse the Fedamore petition against Irish tithes before the end of the session (which, he apparently failed to do).
