For five generations the head of the Acheson family had each at some point sat in the Irish Parliament, a sequence culminating with this Member’s father, who represented county Armagh in the Irish Commons, 1797-1800, and in the United Kingdom Commons from 1801 until he succeeded as 2nd earl of Gosford in 1807. Gosford, who became a representative peer in 1811, had originally been a Tory and anti-Catholic, but gave his support to the Whigs in the 1820s, when he started building Gosford Castle, and joined Brooks’s in March 1828.
Some doubt clearly existed about Acheson’s allegiance since he was considered ‘pro [the duke of Wellington’s] government’ in Pierce Mahony’s† analysis of the Irish elections, while ministers listed him among their ‘friends’, albeit with the annotation ‘crotchet’ beside his name. As he later acknowledged, he did set out to be cautiously sympathetic to the administration, but finding that it ‘went upon no fixed principle of action’, he declined a request to move the address at the start of the session. Then, disgusted by the prime minister’s declaration against parliamentary reform in the Lords on 2 Nov., he voted with opposition in the division on the civil list which led to Wellington’s resignation, 15 Nov. 1830.
Acheson offered again for county Armagh at the ensuing general election, stating that ‘in giving to the measure of reform my warmest support, my sole object has been ... to strengthen and perpetuate our legitimate and constitutional establishments’. Having revealed his disillusionment with the previous prime minister, he praised his successor, who had recently appointed Gosford a lord in waiting to William IV, and was returned unopposed.
He voted for the second reading of the revised reform bill, 17 Dec. 1831, and again for its details. He privately raised some queries about the nature of long leases conferring the franchise with the Irish secretary, Edward Smith Stanley*, and, under pressure from an intended motion of his, which was supported by other Irish Members, changes to this effect were later made to the Irish bill.
