William Mackey Lomasney

Travelling to Ireland to take part in the Fenian Rising in 1865, he was arrested by British authorities in Cork and ordered to leave the country along with John McCafferty.

Upon his return to the United States, he settled in Detroit, Michigan and opened a book and stationery store.

A later member of the American Land League, he became involved in the Clan na Gael and had been in France to make a withdrawal from the treasury of the Irish Republican Brotherhood from which he was to return to Ireland to plan for a possible rebellion with Devoy.

However, as a wave of dynamite bombings occurred in Great Britain during early 1881, he and Devoy would correspond with each other both condemning Rossa's actions and the idea for a "bloodless revolution" in Ireland.

On the early evening of 13 December 1884, Mackey rowed out in a boat with his accomplice John Fleming with the intention of destroying London bridge.
