Was Prince Charles Related to His First Wife, Princess Diana?

Although the thought of marrying someone you may be related to makes many people cringe today, it’s actually a common thing the royals have done for centuries. So while we know some members of the royal family have wed people they are related to, exactly who that is and are how they are related is where things get confusing.

One question that constantly comes up is about the heir apparent, Prince Charles, and if he was related to his first wife, Princess Diana. Of course, the next question after that is whether or not he shares any of the same ancestors with his current wife, Camilla Parker Bowles. Here is the answer to both of those questions, plus some other royal couples you probably didn’t know are related.
