The Marshall Family
Howard Marshall made his fortune in oil and was a billionaire businessman and investor. He once even owned 16 percent of the Koch Industries, a company mentioned before. But perhaps you know him better from the 1994 scandals in the tabloids. At the age of 89, Marshall married 26-year-old Anna Nicole Smith, who was model. The two only spent 14 months of blissful married life before Marshall died. There ensued a bitter long legal battle between Smith and the Marshall family over the family fortune. Even though Anna got to keep a chunk of the Marshall fortune the family still has about $18.5 billion.
