Ultimately descended, like his distant kinsman John Waring Maxwell* of Finnebrogue, county Down, from the clan of Calderwood, Lanarkshire, Maxwell’s ennobled Farnham branch of the family had long been the dominant territorial and electoral force in county Cavan. Henry’s father and namesake, the younger son of another Henry Maxwell, bishop of Meath, whose elder brother was the 1st earl of Farnham, entered the church but apparently resided permanently in northern France, perhaps for financial reasons; Peel, the home secretary, commented derisively in 1823 that ‘such men as Mr. Henry Maxwell, drawing enormous sums from Irish livings, and leading a profligate life at Boulogne, are the real enemies of the establishment’, but a legal connection remarked to this Member in 1830 that ‘your father could, in my opinion, return home and appear, if there was one man in London who would take some trouble and reason with the English creditors’.
Maxwell brought up his county’s anti-Catholic petition, 10 Feb., and was appointed to the select committee on the state of Ireland, 17 Feb. 1825. He voted for the Irish unlawful societies bill, 15, 25 Feb., and against Catholic relief, 1 Mar., 21, 26 Apr., 10 May. He pointed out that it was not he, but John Waring Maxwell, who had made the earlier Commons intervention that was (in fact, erroneously) interpreted as implying his conversion to the Catholic cause, 22 Apr., 9 May.
He spoke at county meetings to address the king on the death of the duke of York and to petition Parliament against Catholic relief, 25 Jan. 1827, and gave his support to his uncle’s scheme to promote the Protestant Reformation in Cavan the following day.
At the general election of 1830, when Maxwell was advised not to ensnare himself with his friend Anthony Lefroy’s* ambitions in county Longford, he maintained a studied neutrality in the muted Cavan contest between his colleague, who was again returned with him despite having voted for the Catholics, and Sir William Young, another local Protestant.
Maxwell vindicated the conduct of the magistracy and yeomanry of county Wexford over the Newtownbarry affray, 23 June, and was forced to return to this topic, 12 July, 26, 27, 31 Aug., 9, 13 Sept. 1831. He voted against the second reading of the reintroduced reform bill, 6 July, at least five times to adjourn the proceedings on it, 12 July, for using the 1831 census to determine the boroughs in schedules A and B, 19 July, and to postpone consideration of the partial disfranchisement of Chippenham, 27 July. He divided against the Irish union of parishes bill, 19 Aug., to censure the Irish government over the Dublin election, 23 Aug., for preserving the voting rights of non-resident freemen, 30 Aug., and for Waldo Sibthorp’s complaint of a breach of privilege against The Times, 12 Sept. He voted against the third reading, 19 Sept., and passage of the reform bill, 21 Sept., and the second reading of the Scottish bill, 23 Sept. He again divided against the Maynooth grant, 26 Sept., and on 6 Oct. criticized Farnham’s being passed over for the lord lieutenancy of Cavan on partisan grounds. He was present at Protestant meetings in Dublin, 7 Dec. 1831, and Cavan, 13 Jan., and was granted leave to attend the assizes, 27 Feb., and again, 5 July 1832.
Described as ‘Orange to the core’, Maxwell was again returned for Cavan at the general election of 1832 and sat as a Conservative until 1838, when he succeeded to the barony which his father had recently inherited from his brother.
