Esmonde was a member of an established and influential Catholic gentry family of Norman descent, his grandfather and namesake having been hanged for his part in the Irish Rebellion of 1798.
Esmonde was appointed captain in the Waterford militia in 1854, and subsequently helped to organise a banquet in honour of Irish Crimean War veterans. He later served on select committees on the system of billeting troops and the pay of General Officers of the Army and, in December 1854, supported the government in the confidence motion on the enlistment of foreigners bill.
At the 1859 general election, Esmonde mounted a strong defence of the Liberals’ record in government and, was again returned unopposed. Involving himself in the Irish schools question, he was a consistent supporter of free education and, while conceding that the system required revision, defended the progress that had been made. In August 1860, he co-signed a letter to the Irish Chief Secretary stating the Catholic position on the future direction of Irish national education. That year he also moved for a select committee inquiry into the system of nomination to naval cadetships, but without success.
Although he was a ‘zealous and attached member of the Roman Catholic communion’, Esmonde steered clear of Cardinal Cullen’s National Association before the 1865 general election when, having successfully explained his support for the Irish peace preservation bill and his absence from the final division on the parliamentary oaths bill, he was re-elected unopposed.
Shortly after being returned unopposed at the 1868 general election, Esmonde inherited the title and estate of more than 8,000 acres in Wexford, Tipperary, Kilkenny, and King’s County from his uncle, Sir Thomas Esmonde, Liberal MP for Co. Wexford 1841-7. He subsequently sat on a select committee on the examination of witnesses upon oath by the Commons, for which he brought in a bill in May 1869.
At the 1874 general election, Esmonde’s position was jeopardised by the home rule movement. While he did not attend the founding meeting of the Home Rule League in November 1873, he did declare in favour of ‘any well-defined system which shall (without endangering the integrity of the empire) transfer to Irishmen the management of purely Irish affairs’.
At his death in December 1876, Esmonde was still regarded as a solidly Liberal figure.
