Are Kevin Bacon and Kyra Sedgwick Cousins? The Truth Explained
Are Kevin Bacon and Kyra Sedgwick cousins? Technically yes, and a televised genealogy study proved it. However, the headline sounds far more dramatic than the reality. The link sits roughly ten generations back, which makes it almost meaningless in practical terms. So, are Kevin Bacon and Kyra Sedgwick cousins in any way that actually matters? No, and the explanation below shows exactly why.
Are Kevin Bacon and Kyra Sedgwick Cousins? The Short Answer
Yes, but only distantly. Kevin Bacon and Kyra Sedgwick are ninth cousins once removed.
That relationship was uncovered on the PBS series Finding Your Roots with Henry Louis Gates Jr. The episode aired in 2012, roughly twenty-four years after the couple married.
They had no idea before the show told them.
How Are Kevin Bacon and Kyra Sedgwick Cousins Exactly?
The connection runs through shared colonial American ancestry. Both come from families that arrived in New England very early, which is exactly why a common ancestor exists at all.
What Ninth Cousins Actually Means
Ninth cousins share a set of eighth great-grandparents. That is around ten generations back from the present day.
To put it in perspective, that ancestor likely lived in the 1600s. Thousands of living people would descend from the same couple today.
The numbers explain why this happens so often. Every generation back doubles your ancestor count, so ten generations gives you over a thousand direct ancestors. Multiply that across an entire population, and distant cousin links become almost unavoidable.
The “Once Removed” Part
“Once removed” simply means the two sit one generation apart on the family tree. One of them is a generation further from the shared ancestor than the other.
It is a technical detail rather than a meaningful one. Genealogists use it for precision, not for significance.
Are Kevin Bacon and Kyra Sedgwick Cousins Close Enough to Matter?
No, and this is the part most headlines skip entirely. The relationship carries no genetic or legal weight whatsoever.
How Much DNA They Share
Ninth cousins typically share no detectable DNA at all. Genetic material gets cut roughly in half each generation, so after ten generations almost nothing survives from any single ancestor.
Consequently, a commercial DNA test would usually not flag them as relatives. Paper records found the link, not biology.
This distinction matters more than people realise. Genetic genealogy and documentary genealogy answer different questions, and a paper trail can prove a relationship that leaves no biological trace at all. Their case is a textbook example of exactly that gap.
Is It Unusual or a Problem?
Not remotely. Anyone with deep colonial American roots has thousands of distant cousins walking around.
Even first cousins can legally marry in many US states. At the ninth-cousin level, the question does not arise in any jurisdiction.
Geneticists draw the practical line much closer than most people assume. Beyond third or fourth cousins, shared ancestry stops carrying any real biological meaning. A ninth-cousin link sits far outside that boundary, which is why no scientist would treat it as significant.
How the Show Proved Kevin Bacon and Kyra Sedgwick Are Cousins
The reveal made for excellent television. Gates traced her family line back through generations of records, then showed her a photograph of a distant cousin she had never identified.
The photo was her own husband. She reportedly reacted with a mix of laughter and disbelief.
Genealogists on the production worked from documentary records such as wills, church registers and census data. You can read more about her response in this Fox News interview.
Did Kevin Bacon and Kyra Sedgwick Know They Were Cousins Before Marrying?
No. They married on September 4, 1988, long before any of this surfaced.
The couple met on the set of the PBS drama Lemon Sky in 1987. Before that, she had briefly met him as a twelve-year-old fan in a Manhattan deli in 1978.
Neither encounter involved family history. The genealogy came out decades later, purely by accident.
Their Marriage Timeline
A quick timeline helps place the discovery in context.
When They Met
They first crossed paths in 1978, when she was a child and he was performing on Broadway. They properly met as adults on a film set in 1987.
When They Married
The wedding took place in September 1988. They have now been together for more than thirty-eight years.
Their Two Children
Travis arrived in June 1989, and Sosie followed in March 1992. Both are adults working in music and acting respectively.
The cousin revelation changed none of that. By the time the episode aired, the couple had already spent well over two decades building a family together.
How Kevin Bacon and Kyra Sedgwick Reacted to Being Cousins
Their responses differed in tone, which is part of why the clip keeps resurfacing.
He found the news genuinely strange at first. Reports describe him as unsettled by it, at least in the moment.
She took the practical view instead. She has pointed out that people with similar colonial ancestry are frequently related somehow, so the finding did not shock her much.
Both moved on quickly. The marriage carried on exactly as before.
They have since joked about it publicly on several occasions. That relaxed handling is probably why the story reads as charming rather than uncomfortable whenever it circulates again.
Why the Story Keeps Going Viral
The clip resurfaces on social media every year or two. Each wave brings a fresh round of exaggerated headlines.
Part of the appeal is the framing. “Actor discovers wife is his cousin” reads dramatically, while “actor discovers wife shares an ancestor from the 1600s” does not.
Context usually gets lost in that translation. As a result, many people come away thinking the pair are close relatives, which is simply untrue.
Short video clips make the problem worse. A thirty-second edit shows the reveal and the shocked faces, then cuts away before anyone explains what ninth cousins means. Viewers are left with the punchline and none of the arithmetic behind it.
The Six Degrees Irony
There is a neat coincidence here worth noting. He is the namesake of the Six Degrees of Kevin Bacon game, which links actors through shared film credits.
So a man famous for improbable connections turned out to have one inside his own marriage. Naturally, the internet enjoyed that far too much.
The game itself dates to the 1990s and rests on a real mathematical idea about small networks. Family trees behave in a similar way, since everyone connects to everyone else if you trace far enough back.
Not Looking for the Actors?
Some visitors reach this page while searching for something completely different. The Sedgwick name also belongs to a large county in Kansas, and that county drives far more record-related searches than either actor does.
If that is your situation, our inmate search Sedgwick County guide walks through locating someone in custody. Our Sedgwick County jail inmates page explains how the custody list is organised and updated.
Neither performer has any tie to that county. The shared name is pure coincidence, and the county itself was named after a Civil War general rather than anyone in the family.
FAQ: Are Kevin Bacon and Kyra Sedgwick Cousins
Are Kevin Bacon and Kyra Sedgwick cousins by blood?
Technically yes, at the ninth-cousin level. In practice they share little or no detectable DNA, so the label overstates the reality.
How distant is ninth cousins once removed?
Very distant. It means a common ancestor roughly ten generations back, likely born in the 1600s.
Which show revealed the connection?
Finding Your Roots with Henry Louis Gates Jr., on PBS. The episode aired in 2012.
Did the discovery affect their marriage?
No. They stayed together and rarely bring it up except when asked directly.
Are most people distantly related like this?
Often, yes. Anyone with deep roots in one region will have countless distant cousins they will never identify.
Does this affect their children?
Not at all. A ninth-cousin link has no genetic consequence for their children.
Are Kevin Bacon and Kyra Sedgwick Cousins? Final Verdict
So, are Kevin Bacon and Kyra Sedgwick cousins after all this? Yes on paper, and no in any way that matters.
They are ninth cousins once removed, connected by an ancestor who lived roughly four centuries ago. That places them alongside thousands of other people who happen to share the same colonial lineage.
The couple learned about it on television, laughed about it, and stayed married. Treat the story as trivia rather than scandal, because that is exactly what it is.
If a headline ever tells you otherwise, check the degree before reacting. The number in front of the word cousin does all the work here, and in this case that number is nine.
