4. Camilla, Duchess of Cornwall
Marrying a prince surely has it’s financial benefits, but Camilla was far from destitute when she married Prince Charles in 2005. Prior to her induction into the royal family, she owned a home that was estimated to be worth around $2.5/£1.9 million. As the Duchess of Cornwall, she receives benefits from the Duchy of Cornwall estate in exchange for her royal duties like Prince Charles does. Her estimated net worth is said to be in the vicinity of $5/£3.8 million.
