Part 2 of 2. In the leafy suburbs of South Belfast, journalist Ita Dungan discovered thousands of receipts in the attic of her Victorian terraced house. They reveal the middle class life enjoyed by Robert Smith, his wife Jeannie and their four children - Robert Cecil, Florence Eileen, Edward Ivan McCullagh and Donald Edgeworth. With the help of historian Dr Alice Johnson and newspaper reports, Ita discovers the controversial source of Robert’s wealth, a diamond ring heirloom and the forgotten ‘other woman’. The fate of the Smith family is revealed - involving emigration and World War II battles. But what of their descendants? Will Ita find any? Produced by Cathy Moorehead
