Trivia: What title of nobility did Diana’s father hold?
Prince
Earl
Knight
Baron
The correct answer is Earl
So why is this answer correct? : At the time of her birth, Diana’s parents, John and Frances Spencer, held the title of viscount and viscountess. In 1975, John inherited the title of earl, making him the eighth Earl Spencer. The Earls of Spencer date back nearly 300 years, with the first Earl Spencer born in 1734. An earl is the oldest British nobility ranking and is third in precedence, behind duke and marquess.
