The original 2-part documentary proved so popular with viewers that ITV commissioned a four episode second series. In each episode of series 2 two celebrities will explore their family histories. The four pairings are comedians Rob Beckett & Romesh Ranganathan, sporting legends Freddie Flintoff & Jamie Redknapp, entertainers Amanda Holden & Alan Carr and father and son Martin & Roman Kemp. Series 2 is expected in early 2021. In a separate move, BBC Studios have bought the rights to sell international versions of the format outside the UK.
