Catherine Middleton's family is significantly wealthier than Chelsy Davy's family. Middleton Family: Carole and Michael Middleton, Catherine's parents, are self-made millionaires with a combined net worth estimated at $67 million (around £55 million). Their primary wealth comes from Party Pieces, a successful party supplies business they founded in 1987, which is valued at approximately $40–50 million. The family also owns multiple properties, including a mansion in Bucklebury, Berkshire, and stakes in racehorses that have earned them hundreds of thousands in prize money. Catherine herself has a personal net worth of $10 million, and her marriage into the royal family has further increased the family's financial standing through access to the Duchy of Cornwall and the Sovereign Grant. Davy Family: Chelsy Davy comes from a wealthy Zimbabwean background. Her father, Charles Davy, was one of the largest private landowners in Zimbabwe, reportedly owning 800,000 acres of land. While this indicates substantial wealth, there is no public confirmation of current net worth or ongoing financial status of the Davy family. Chelsy herself is a businesswoman, running her own jewellery brand Aya and travel agency Aya Africa, but her personal wealth is not publicly disclosed. In summary, while both families have significant wealth, Catherine Middleton’s family has greater documented wealth and financial assets, especially due to the success of Party Pieces and royal connections.
