James Bermingham (1849–1907) was a prominent "advanced nationalist" in Dublin during the last quarter of the nineteenth and early part of the twentieth centuries.
James Bermingham was born in Dublin in December 1849. The church register of St. Nicholas of Myra, Francis Street, Dublin, shows that he was baptised there on Monday, 17 December 1849. His father was Peter Bermingham and his mother was Ellen Flood. The sponsors at his baptism were James D'Arcy and Bridget Daly. The officiating priest was Fr. Nicholas O'Farrell, curate.
In his personal life, James Bermingham was a Plumber and Sanitary Contractor living at 26 Cuffe Street, Dublin. He married Margaret Byrne, a native of County Wicklow, in St. Andrew's Church, Westland Row, Dublin on 21 September 1873.
James Bermingham was a veteran of the 1867 Fenian Rising. As a member of the Irish Republican Brotherhood he was present at the attack on the police barracks at Tallaght. At the funeral of James Stephens the founder of the Irish Republican Brotherhood on 31 March 1901, James Bermingham was one of the pall bearers along with Michael Davitt, C. G. Doran, Michael Lambert, William Brophy and William Hickey – all '67 veterans.
James Bermingham was an honorary treasurer of the later Irish National Amnesty Association, operating from the Workmen's Club at 41 York Street, Dublin, which campaigned between 1892 and 1899 on behalf of the Irish and Irish-American political activists who were imprisoned during the 1880s. He was a mainstay of the Association, and contemporary newspaper reports show the range of his work.
On 13 August 1898 the Kentucky Irish American newspaper reported on a visit by James Bermingham and Mr. T. Kelly (Secretary of the Amnesty Association) to Tom Clarke (alias Henry Wilson) to Portland Prison, Dorset. The report was as follows:
