Find My Past the TV show
I imagine it takes a similar format to Who Do You Think You Are but with ordinary people. Each episode features three members of the public who are connected to each other through an event in history. This week will be about the Mutiny on the Bounty.
The program goes out on Thursdays at 9pm on the Yesterday Channel: Freeview channel 12, Sky 537 and Virgin Media 203. I understand that repeats are aired the next day.
