It is one of those facts that feels like a glitch in the simulation. You have Lewis Capaldi, the self-deprecating, chart-topping king of "sad bangers" and Instagram comedy. Then you have Peter Capaldi, the Oscar-winning actor, the legendary Twelfth Doctor, and the man who turned "Malcolm Tucker" into a sweary art form. They share a surname, a Scottish heritage, and a specific kind of expressive face, but for a long time, fans just assumed it was a coincidence.
It isn't.
The connection between Lewis Capaldi and Peter Capaldi is very real, even if it is a bit distant. They aren't father and son. They aren't brothers. But they are family. Specifically, they are second cousins once removed.
If your brain just short-circuited trying to map out a family tree based on that phrase, don't worry. Basically, it means Peter is the second cousin of Lewis's father. Despite the shared bloodline, they didn't actually grow up together or spend Christmases swapping stories about the Glasgow acting scene and Top 40 radio. In fact, for most of Lewis’s life, Peter was just that "famous guy on the telly" that his dad and aunts would point at whenever Doctor Who or The Thick of It came on.
How the Capaldi Connection Actually Works
Let’s get into the weeds of the genealogy for a second. The Capaldi family traces its roots back to Italy—specifically Picinisco, a small village in the Comino Valley. Like many Italian families who migrated to Scotland, they brought a strong sense of identity with them, but as the generations spread out across Glasgow and West Lothian, the branches of the tree grew pretty far apart.
Lewis has been open about the fact that his family always told him about the link. "My dad and my aunties told me we were related to Peter a while ago," he told the Daily Record. But it wasn't like he had Peter’s number in his phone.

The two stars didn't actually meet until Lewis was already becoming a household name. In 2018, Peter decided to head along to one of Lewis’s shows in London. He went backstage afterward, and that was the first time they ever shook hands. Imagine that: meeting your famous relative for the first time while you’re both already famous. Kinda surreal.
That Music Video Everyone Cries At
The most famous intersection of Lewis Capaldi and Peter Capaldi happened in 2019. If you’ve seen the music video for "Someone You Loved," you know exactly why it has hundreds of millions of views. It isn't just a performance video; it’s a devastatingly beautiful short film about organ donation.
Lewis wanted to do something that raised awareness for the charity Live Life Give Life. His mother, a nurse, had introduced him to the cause. While sitting in a meeting with his label, Lewis flippantly suggested they ask Peter to star in it. He didn't think it would actually happen.
But it did.
Peter Capaldi didn't just say yes; he did it for free. He was so moved by the cause and Lewis’s talent that he jumped on board immediately. He plays a widower who finds comfort in meeting the woman who received his late wife’s heart. His performance is—honestly—masterful. There is a moment where he puts his hand on the recipient's chest to hear the heartbeat, and if you don't well up at that, you might be a robot.

Why People Get the Relationship Wrong
The internet loves a simple narrative. People often assume Peter is Lewis's uncle. It makes sense on paper—older, successful mentor type and the younger rising star. But the "once removed" part of their relationship is what trips everyone up.
- Second Cousin: You share great-grandparents.
- Once Removed: There is a generation gap between you.
So, Peter and Lewis’s father are second cousins. Because Lewis is a generation below them, he becomes the "once removed" part of the equation.
A Shared Scottish Legacy
Beyond the DNA, there’s a shared vibe between the two. Both men have a reputation for being incredibly kind and remarkably humble despite their massive success. Lewis has often cited Peter as an inspiration, not because of the fame, but because of the longevity of his career.
It’s also worth noting that they aren't the only talented Capaldis out there. The name pops up throughout the arts, often tracing back to that same Italian-Scottish lineage. But Lewis and Peter remain the "Big Two" in the public eye.
When Lewis had to step back from the spotlight recently to focus on his health and his struggle with Tourette’s, fans were quick to point out the supportive nature of his extended family. While they might not be "Sunday roast every weekend" close, there is a clear mutual respect. Peter has called Lewis a "remarkable talent" and a "great guy."

The story of Lewis Capaldi and Peter Capaldi is a reminder that the world is smaller than we think.
