People often talk about Diana Spencer as if she was some sort of commoner who got lucky and landed a prince. Honestly? That couldn't be further from the truth. If you look at the princess diana spencer family tree, you’ll realize she wasn’t just "noble adjacent"—she was arguably more English-royal than the man she married.
While the Windsors (formerly the House of Saxe-Coburg and Gotha) have deep Germanic roots, the Spencers are quintessentially British aristocrats. They’ve been power players in England since the 15th century. We’re talking about a family that built a fortune on sheep farming before transitioning into land ownership and becoming one of the wealthiest dynasties in the country.
By the time Diana was born in 1961, her family had been living at the Althorp estate for nineteen generations. You've probably heard of it. It’s that massive 13,000-acre property in Northamptonshire where she is eventually laid to rest.
The Spencer Lineage: Not Just "Lady" Di
Diana wasn't born a "Lady." She started as The Honourable Diana Frances Spencer. It wasn't until 1975, when her father inherited the Earldom, that she got the title most of the world first knew her by.
Her father, John Spencer, 8th Earl Spencer, was a man of serious pedigree. He served as an equerry to both King George VI and a young Queen Elizabeth II. Proximity to the crown was basically the family business. In fact, when Johnnie Spencer (as he was known) married Diana’s mother, Frances Roche, in 1954, the Queen herself was a guest at the wedding.

The Roche Connection
Don't overlook the maternal side. Diana’s mother, Frances, was the daughter of the 4th Baron Fermoy. Her grandmother, Ruth Roche, Baroness Fermoy, was a total powerhouse. She was a close confidante and lady-in-waiting to the Queen Mother.
There's this sorta famous bit of royal gossip that Lady Fermoy and the Queen Mother actually orchestrated the match between Diana and Charles. While Lady Fermoy later denied it (and allegedly didn't even think they were a good match), it shows just how deeply embedded the Spencers were in the palace inner circle.
The Stewart Secret: Why Diana’s Blood Ran Purple
Here is the part that usually blows people’s minds. Through the princess diana spencer family tree, Diana was a direct descendant of King Charles II and King James II.
The catch? These lines came through illegitimate children.

Because of this, Diana actually had more "English" royal blood in her veins than Prince Charles did at the time of their marriage. She descended from the House of Stuart via several lines, including:
- Henry FitzRoy: The illegitimate son of Charles II and Barbara Villiers.
- Charles Lennox: Another illegitimate son of Charles II.
- Arabella Churchill: The mistress of James II and sister to the Duke of Marlborough.
Basically, Diana brought the blood of the old Scottish and English kings back into the British royal line. When William eventually takes the throne, he will be the first British monarch descended from Charles II since the Stuarts were ousted in 1688. That’s a massive deal for history nerds.
Winston Churchill and Other Surprising Cousins
The "Spencer-Churchill" name isn't a coincidence. The two families are inextricably linked. The 3rd Earl Spencer married Lady Anne Churchill, the daughter of the 1st Duke of Marlborough.
This makes Winston Churchill Diana's distant cousin. Specifically, they share the same ancestors in Charles Spencer and Anne Churchill. If you look at photos of a young Winston and a young Diana, you can almost see the family resemblance in the stubborn set of the jaw.

But the tree doesn't stop in England.
- American Presidents: Diana is distantly related to George Washington, John Adams, and Franklin D. Roosevelt.
- Hollywood Royalty: She’s a cousin to actors like Glenn Close, Humphrey Bogart, and even Audrey Hepburn.
- The "Original" Lady Di: In the 1700s, there was another Lady Diana Spencer. Her family tried to marry her off to the Prince of Wales back then, too. It didn't happen, and she ended up marrying the Duke of Bedford, but the parallels are eerie.
The Modern Spencer Tree
The family name continues today through Diana's brother, Charles Spencer, 9th Earl Spencer. He’s the one you likely remember from that blistering eulogy at her funeral. He has seven children, including Lady Kitty Spencer, who has become a fashion icon in her own right.
Then, of course, there are the "Royal Spencers"—Prince William and Prince Harry. While they carry the Windsor name, both have gone to great lengths to honor their Spencer heritage. Whether it's William giving Catherine Diana's sapphire engagement ring or Harry including his mother’s sisters, Lady Sarah McCorquodale and Lady Jane Fellowes, in official family portraits, the Spencer influence is everywhere.
Actionable Insights for Genealogists
If you’re researching the princess diana spencer family tree for your own historical projects or just out of curiosity, keep these specific points in mind:
- Check the Marlborough Line: Many of Diana’s most famous ancestors (like the Churchills) come through the marriage of the 3rd Earl of Sunderland to Anne Churchill.
- Look for the "Illegitimate" Links: Much of the royal Stuart ancestry is found through the Dukes of Richmond and Grafton, who were the descendants of Charles II's mistresses.
- Visit Althorp: If you're in the UK, the estate is often open to the public in the summer. Seeing the Spencer family portraits in person gives a much better sense of the lineage than any digital chart.
- Use the Peerage Records: Unlike commoner genealogy, noble trees are meticulously documented in "Burke’s Peerage" and "Debrett’s." These are the gold standards for verifying Spencer dates and titles.
The Spencer family wasn't just a backdrop for Diana's life. It was the foundation of her identity. She didn't become "someone" when she married Charles; she already came from one of the most significant bloodlines in British history. Understanding that changes how you see her entire story.
