Ennis was one of the most successful and wealthy businessmen in Ireland and a large landed proprietor. A moderate Liberal, he held aloof from popular political movements, and it has been argued that he used his wealth ‘to forge a barefaced cash relationship with the electors, one in which national issues and interests played little part’.
Born in Dublin, where his family controlled large business interests, Ennis was the only son of ‘one of the prince merchants’ of the city, who in 1801 had purchased an estate at Griffinstown, county Westmeath, and later acquired a seat at Ballynahown, near Athlone.
Ennis’s father had for many years been treasurer to the O’Connell Tribute, but although the son had parliamentary aspirations he was not thought by the O’Connell’s to have ‘any great chance at Athlone’ at the 1835 general election.
Ennis regarded himself as ‘one of the pioneers of the railway system in Ireland’. He resigned from the board of the Great Southern and Western Railway in 1845 because he believed that the company had been mismanaged, but soon afterwards joined the Midland Great Western Railway as deputy chairman.
Ennis had been fiercely opposed to the repeal of the corn laws and in 1850 joined a committee to establish an Irish Protectionist Society.
Despite being described as ‘an ardent votary’ of the Catholic Church, Ennis did not enjoy the confidence of the Liberal party in Ireland, and declined to take on Keogh at Athlone when the newly appointed Irish attorney-general stood for re-election in March 1855.
Ennis supported the Liberal ministry on religious issues affecting Ireland, such as the ministers’ money bill, 19 May 1857, and routinely divided in favour of the abolition of church rates and against anti-Maynooth motions. He was in the minority that backed Deasy’s amendment to the oaths bill, calling for a uniform parliamentary oath, and voted with the majority against Thesiger’s subsequent attempt to exclude Jews from parliament, 15 June.
Having openly promised railway patronage to voters, Ennis was re-elected for Athlone in 1859 and, as was revealed some years later, secured numerous votes by providing loans to electors, which were not redeemed provided that they voted appropriately.
For the rest of his time in parliament Ennis largely supported Palmerston’s ministry. He was opposed to triennial parliaments, and had divided against Henry Berkeley’s ballot motions in 1857-8. However, he backed the measure, 20 Mar. 1860, but abstained from voting on the matter thereafter. On 4 June 1860, during the committee stage of the representation of the people bill, Ennis gave notice of a motion instructing that ‘one uniform Oath should be administered to all Members on taking their Seats in this House; and that such Oath shall be in future that of allegiance and fidelity to the succession only’, only for the motion to be ruled out of order by the speaker.
Ennis had been an early financial backer and vocal supporter of John Orrell Lever’s plan to provide a direct mail service between Ireland and America via Galway, and had been instrumental in securing the support of the Dublin Chamber of Commerce for the scheme.
Ennis’s record in parliament did not accord with the wishes of many of his constituents, and was condemned by the local Catholic bishop as ‘selfish, uncatholic, and unpatriotic’. He was easily beaten at the 1865 general election by a London-based estate agent, who, it was said, had been advised by Ennis’s wife to seek a seat at Galway, but had decided to contest her husband’s constituency instead.
His son having secured the seat at Athlone in 1868, Ennis offered for County Westmeath in June 1871, but retired from an apparently hopeless contest against a Nationalist candidate. He then quit parliamentary politics and devoted himself to his business affairs and the running of his estates, dying intestate at his residence in Merrion Square, Dublin, in August 1878.
