Allen family.

William Philip Allen was executed November 23, 1867, in England for his participation in the Fenian Rebellion of 1867. The goal of this revolutionary rebellion was to establish an Irish republic. He was arrested and executed for his participation in the prison van rescue of fellow Fenians on September 18, 1867. The rescue was thwarted but not before the constable in charge of the van was killed. The would-be Fenian rescuers became known as the "Manchester Martyrs" Bitter public feeling was aroused in Ireland by their conviction on what many regarded as weak evidence.
