Is Graham Hornigold Married? Where is Graham Hornigold Now?

If you’ve recently watched Nick Green’s jaw-dropping documentary Con Mum, then you’ve probably found yourself asking: Is Graham Hornigold married? The story of the acclaimed pastry chef who found himself emotionally and financially entangled in a dramatic reunion with his biological mother has left viewers stunned—and deeply curious about his life outside the camera lens. Let’s break it all down in a real, conversational way.

So, Is Graham Hornigold Married?

As of 2025, Graham Hornigold is not married. However, he was previously in a long-term relationship with fellow pastry chef Heather Kaniuk. The two were more than just romantic partners—they were also professional collaborators. Together, they co-founded Longboys, a creative doughnut and coffee business that has since become a staple in the London food scene.

Their relationship was serious and full of shared dreams. At one point, they were preparing to welcome their son into the world, building a family while building a brand. But life had other plans.

The Dionne Saga That Changed Everything

Just as things seemed to be heading toward a fairy-tale chapter—new baby, thriving business, solid partnership—Graham’s life was thrown into chaos. In 2020, he met a woman named Dionne Marie Hanna, who claimed to be his biological mother. She came armed with convincing stories, personal details, and emotional urgency. She said she was dying and wanted to spend her final months with her long-lost son.

For someone like Graham, who had grown up without his mother and had endured a traumatic childhood, this reunion felt like a long-awaited piece of healing. But it didn’t take long for things to spiral.

Dionne promised Graham and Heather a lavish inheritance, claiming royal ties to Southeast Asia and enormous wealth. In the meantime, she pulled them into a whirlwind of first-class travel, five-star hotels, and expensive legal meetings—all of which were funded, at least in part, by Graham himself.

By the time the dust settled, Graham was over $300,000 in debt, emotionally drained, and heartbroken. The promises of inheritance turned out to be fabricated. Dionne’s cancer? A lie. And while she is his biological mother, her actions left scars that would take far longer to heal than just financial losses.

What Happened to Graham and Heather?

Unfortunately, the intense stress and betrayal they endured during this period took a toll on Graham and Heather’s relationship. While they were never legally married, they were, for all intents and purposes, life partners. But even strong bonds can fray under the weight of deception, trauma, and massive debt.

Eventually, the couple decided to separate. Heather Kaniuk moved to New Zealand with their son, and Graham stayed behind in the UK to try and piece his life back together.

Still, he remains a dedicated and present father. Graham talks about his son often, and even though they live in different countries, he makes it clear that being a part of his child’s life is a top priority.

“I won’t let it [the situation with Dionne] affect him in the sense that he won’t see his dad,” Graham told The Guardian. “I’m going to be a big part of his life.”

That right there tells you the kind of man he is—one who values commitment, even in the most difficult of circumstances.

Career: Rising From the Ashes

Despite the personal storm, Graham Hornigold’s career hasn’t slowed down. If anything, his work ethic seems stronger than ever. He remains the Director of Longboys, which has now expanded to multiple locations across London, including Borough Yards, King’s Cross, and Market Halls Canary Wharf.

He’s also the founder of Smart Pâtisserie, a consulting business he originally launched with Heather. In 2023, the duo acquired Pretty Sweet, a luxury food and beverage company, further growing their empire.

And let’s not forget—Graham was featured at The Artisan Collective 2025, hosted by British Baker, where he led attendees through a hands-on baking session. So yeah, the man’s still got it.
