Three Families cast revealed in full for new BBC One drama

Meet the Three Families 2021 cast

Three Families has arrived on BBC One – here’s a full run down of who’s on the cast.


The new two-part series is based on Northern Ireland abortion laws and was first announced back in 2019.

A teaser shares: “A mother faces prison for trying to help her pregnant teenage daughter. Two young newlyweds learn that their much-wanted first child will die of a fatal foetal abnormality. If they lived in England, Wales or Scotland, both families could seek a legal termination. But this is Northern Ireland, where abortion laws have been among the most restrictive in Europe.

“Based on true stories, Three Families is a compelling and thoughtful two-part drama from screenwriter Gwyneth Hughes. It explores the emotional background to a controversial campaign which culminated in the UK government forcing a liberalisation of the law in Northern Ireland.”

But as word starts to get out, she discovers that she could face a prison sentence for breaking one of Northern Ireland’s most controversial laws.
