Podcast Review: DNA Trail – The promise

Our sense of identity helps anchor us in a world that is constantly shifting – our bodies age, our interests change, new technologies suddenly reshape how we live. In a life full of plot twists, our identity can feel like the author bio at the back of a novel: a reminder of where we come from, and a hint at why our personal story might be worth the read.

For Billy Ancell, that grounding was missing. DNA Trail: The Promise opens with an international phone call, in which we hear Billy's trepidation as he speaks to a man named William Anderson. Billy is cold-calling to ask whether William remembers meeting his mother, Madeleine, in Brighton during WWII while serving with New Zealand's Air Force – and possibly fathering him. William vaguely recalls Madeleine, but hesitates. He promises to get back in touch and send photographs.

Of course, had he done so, I would not be reviewing this podcast. Billy died of cancer shortly after that call, without ever knowing the truth about his father. On his deathbed, his daughter Laura and her mother Jayne promise to complete his search for belonging – a journey that began in 2009 and is condensed into eight brisk, 20-minute episodes.

In the first half of the series, we follow Laura as she traces the steps that brought William Anderson to the UK, set against light-touch historical context from WWII. We get to know Billy – a charming flamenco guitarist, dearly loved by his wife and daughter. I found myself growing fond of him too, and sympathising with his unmoored sense of self. Alongside his story, we get a glimpse of genealogy in the early internet era, when hobbyists eagerly embraced the new tools that allowed them to track down long-lost relatives with unprecedented ease.

The episodes flow well, thanks to Laura's assured storytelling – though at times, the narration veers toward the overly sentimental, a sentiment amplified by the grandiose choice of music. By episode three, I thought I had my daily fill of other people's family drama. But then, in episode four, a twist lands via an SMS (yes, a Short Message Service), and the story takes a gripping new turn. From here, the podcast really shines. What had seemed like a wholesome family quest becomes a rollercoaster of revelations, missteps, and incredible coincidences that test Laura and Jayne's emotional resilience – and their promise to Billy – as they travel back and forth to New Zealand.

Laura skillfully weaves together interviews, archival recordings, and occasional re-enactments, creating an experience that feels immersive rather than scripted. As a narrator and investigator, Laura is compelling: personally invested, ethically engaged, and determined to uncover the truth. At times, her conviction in her 'right to know' leads her to take bold, even intrusive, steps – knocking on strangers' doors or asking probing questions. I initially wondered whether the podcast lacked enough reflection on the ethics of this approach. But later episodes prove me wrong, showing Laura and Jayne grappling honestly with their own mistakes and their impact on others.

The podcast includes a brief but thoughtful discussion of the ethical dilemmas surrounding consumer DNA tests – one that, while not comprehensive, goes beyond the subtle hinting typical of Jenny Kleeman's The Gift (see BioNews 1210, 1217, 1267 and 1269). I also appreciated its clear and accurate explanation of how to interpret sibling and paternity testing, and how reliable (or not) these tests really are.

This is ultimately a story about perseverance – but the ending stood out to me most. Equipped with evidence of her paternal New Zealand roots, Laura applied for citizenship, only to be denied because she was born 'out of wedlock' – to me, an outdated and discriminatory term. She challenged the decision through the Human Rights Commission and, thanks to her persistence, was invited to reapply under 'exceptional circumstances'. She became a New Zealand citizen in 2023.

Not stopping there, Laura launched a petition to change the law, arguing that children of unmarried parents should have an equal right to citizenship. Her campaign continues.

'So many people have family histories shaped by migration, separation, and reconnection,' Laura reflects in an interview. 'I hope the podcast sparks conversations about family history and encourages people to reach out, ask questions and embrace the connections that make them who they are.'

DNA Trail: The Promise is more than a compelling mystery – it's a portrait of perseverance. By the end, it feels as though the bio at the back of Laura's story is finally complete. And it's a story worth reading.
