Season 5 - Episode 2 - Aired 8/21/2008

Boris Johnson knew a certain amount about his diverse family background, but was intrigued by several family stories and mysteries. He was particularly keen to investigate stories associated with the relatives of his paternal grandparents. Boris's grandfather, Wilfred Johnson, had never spoken about the murder of his Turkish father in the 1920s. Boris’s grandmother Irene Johnson (née Williams), known as 'Granny Butter', had always been the subject of derision in the family due to her grandiose claims of an aristocratic French background. So Boris set out on an international journey of discovery to separate fact from fiction.

Ruby Wax's Jewish parents fled Vienna and the Nazis for America in 1938. 'They took the war with them and brought it to our kitchen,' says the comedian and mental-health campaigner at the start of this remarkable episode. They raised their only daughter in a dramatically dysfunctional household - Ruby's father was volatile and her mother 'hysterical... screaming in the street.' Ruby wonders if her own mental illness had its origins in her upbringing and the trauma her parents went through, or whether it is in her family's genes. Ruby journeys to central Europe, where she learns about her parents' flight and the distressing fate of family who remained in Vienna during the war, and she makes a startling discovery about her great-aunt and great-grandmother, which is both harrowing and surprisingly affirming.

Patsy's late father was a villain. Jimmy Kensit was deeply involved with the most notorious gangsters of 1960s London: the Krays and the Richardsons. Reggie Kray was even godfather to Patsy's brother. Apprehensively, Patsy embarked on an investigation into her father's murky past, to understand the roots of his criminality and to discover how far back 'the family trade' goes. Patsy met up with a criminologist who had unearthed a copy of her father’s criminal record, revealing the true extent of his crimes. She was then shocked to uncover documents in the National Archives that show her grandfather was also a prolific criminal. After more research, Patsy was at last relieved to discover that her great-grandfather, though impoverished, was an honest walking stick maker. Tracing her roots even further back, an amazing document in Goldsmith's Hall revealed how the Kensit family, once affluent artisans, first fell into terrible poverty. Ultimately Patsy made the emotional discovery that rather than descending from a long line of villains, one of her ancestors was a remarkable vicar who dedicated his life to helping the poor.
