Castle Rackrent
Shortly before it was published, an introduction, glossary and notes were added because the family thought people might think it was against  the Act of Union 1800. It is partly based on her own family history, The Black Book of Edgeworthstown.  The novel is set in Ireland before the Constitution of 1782. It tells the story of four generations of Rackrents and how badly they managed the estate. They were  Anglo-Irish landlords.
