From A Compendium of Irish Biography, 1878
Duffy, Edward, a Fenian leader, was born at Ballaghadereen, County of Mayo, in 1840. In 1863 he gave up a situation and devoted himself to spreading Fenian principles in Connaught. He was arrested, November 1865, in company with James Stephens, at Fairfield House, Sandymount, and was sentenced to a term of imprisonment; but was liberated on bail in January 1866, in consequence of ill health. He again applied himself to the organization, was re-arrested, and tried again in May 1867, and sentenced to fifteen years' penal servitude. He died in Millbank Prison, 17th January 1868, aged about 28. A portion of his speech delivered in the dock before conviction has been inscribed on his tomb at Glasnevin.
