Eneclann conducts professional research services and electronic publishing for Irish history. The company is based at Trinity College in Dublin and is staffed by academic historians, archivists, and genealogists. According to the promotional material, this petition, signed by over 80,000 people from every part of Ireland and from Liverpool, Manchester, and other parts of England, between 1848 and 1849, is a unique historical and genealogical source from the period of the Famine. Following the failure of the 1848 rising, O Brien was sentenced to death, and this petition was collected to gain clemency for the rebel leader. As a consequence his sentence was commuted and O Brien was transported to Australia for life.
