It is sometimes said that the only difference between the truth and fiction is that fiction needs to be plausible. Margaret Gaffney Haughery is a case in point. If Charles Dickens had written her life story, even he would surely have paused at some point and thought, “Wait! Am I laying this on too thick?”

Margaret Gaffney was born on Christmas Day 1813, in Tully, Co Leitrim. Five years later, faced with extreme poverty and religious persecution, her parents and the three youngest of their six children, including Margaret, boarded a steamer bound for Boston.
