Portion of a brick in which is embedded a bullet, fired by the firing party which executed Mr Francis Sheehy Skeffington at Portobello Barracks, 26 April 1916; the bullet passed through the body of Mr. Sheehy Skeffington.

Francis (‘Frank’) Skeffington married his wife Hanna in 1903. The couple were committed to many causes, particularly feminism, pacifism, socialism, and nationalism; when the couple married (1903) they took each other's surnames as a symbol of the equality of their relationship.

On the outbreak of the 1916 rising Frank was involved in organising anti-looting bands. He was arrested and shot without trial on the orders of Capt. J. C. Bowen-Colthurst, a British army officer. Hanna was thrown into personal and emotional turmoil by that event. An inquiry into the murder left too many questions unanswered for her satisfaction. She refused all offers of compensation from the government.
