A DNA test intended to explore family ancestry can sometimes reveal far more than expected. For Toronto performer Noam Tomaschoff, a test in 2022 uncovered a family secret that changed his understanding of his identity and eventually led him to discover more than 35 half-siblings he had never known existed. What followed was an unexpected journey involving family reunions, difficult conversations and a musical based on his discovery.In a November 11, 2026, report, The Washington Post’s Sydney Page detailed how Tomaschoff transformed the experience into Our Little Secret, a musical based on his family’s story. The production recently became the setting for another emotional moment when seven of his half-siblings travelled from the United States to Canada and surprised him at a Toronto performance.
DNA test revealed an unexpected family history
Tomaschoff’s discovery began in 2022, when he bought a DNA test kit. After he mentioned the purchase to his mother, his parents told him the next morning that the man who had raised him was not his biological father. Recalling his reaction, Tomaschoff told The Washington Post, “I was profoundly shocked. I had never remotely considered this to be a possibility.”He also described the experience of having his understanding of his family changed, saying, “It was like meeting aliens,” to The Washington Post. Two months later, the test results revealed that he had at least 15 half-siblings conceived through the same sperm donor. He subsequently identified 20 more, bringing the total to more than 35. The discovery prompted him to investigate his biological origins and establish contact with some of his newly found siblings.The revelation also brought a complicated set of emotions. While the discovery created opportunities to connect with people who shared his background, it required him to reconsider parts of the family story he had previously understood.
Turned family secret into a musical
Rather than keeping the experience private, Tomaschoff decided to explore it through theatre. He created Our Little Secret, a musical inspired by his DNA discovery and the complicated family relationships that followed.The production combines personal experiences with humour and music to examine themes of identity, parenthood, family secrets and unexpected connections. By presenting the story on stage, Tomaschoff found a way to explore a deeply personal subject while allowing audiences to reflect on the broader questions it raises about family and belonging.The musical was first presented at the Toronto Fringe Festival in 2023 as Our Little Secret: The 23andMe Musical. The production featured Tomaschoff as its creator and performer. The musical later travelled to other cities before returning to Toronto for a larger production at CAA Theatre. According to the show’s official website, its November 2026 run was scheduled from November 3 to 22.Tomaschoff’s parents were initially uncomfortable with the idea of their long-kept family secret being revealed publicly through the musical. However, they eventually embraced the production. “They came around, and now we feel like this show really represents us as a family,” Tomaschoff told The Washington Post.
Seven half-siblings surprised him in Toronto
The latest development in Tomaschoff’s story came during a Toronto performance when seven of his half-siblings travelled from the United States to surprise him. Their appearance turned an ordinary performance into an unexpected family reunion. The siblings’ decision to attend the show also reflected how a discovery made through a DNA test had developed into real relationships and connections across national borders.For Tomaschoff, the reunion brought the story behind the musical into the theatre itself. The people whose shared biological history had inspired the production were now part of the audience, making the experience especially meaningful.
A personal discovery became a shared story
Tomaschoff’s experience highlights how consumer DNA testing can reveal unexpected biological relationships and reshape people’s understanding of their families. Such discoveries can bring excitement and opportunities for connection, but they can also raise difficult questions about identity, parenthood and long-kept secrets.Through Our Little Secret, Tomaschoff has turned his personal experience into a theatrical production that allows audiences to engage with these questions. The surprise appearance of seven half-siblings at his Toronto show added another chapter to a story that began with a DNA test and developed into an expanding family connection.
