Who Do You Think You Are? (2004)

S5E4 Esther Rantzen

Esther has always perceived her family as cultured and honorable, so she's puzzled by the swirling rumors of bigamy, fraud, and even murder surrounding them. Captivated by tales of a 'black sheep,' she becomes curious about the Rantzen lineage. Her quest for the truth leads her from the impoverished streets of Spitalfields in London to the diamond mines of South Africa. Throughout her journey, she uncovers the incredible tale of someone on the run from the law.
