The Marshall Family – $9 Billion.
The Marshall family made their money the old fashioned way: by making smart investments. You see, the Marshall family invested in a 14% stake of Koch Industries and soon they were well rewarded for their faith in the company.
The Gallo Family – $10.3 Billion.
If you enjoy a nice glass of vintage wine then you will definitely respect the Gallo Family. The Gallo family got their start back in 1933 in a little shed out in Modesto, California. They sold their wine initially for just a buck a gallon and soon were involved with wholesalers across the country. Since then the Gallo family has turned into one of the largest winemaking companies in the world.
