The Duncan Family – $24.8 Billion
Dan Duncan founded gas and oil company Enterprise Products Partners back in 1968 with just $10,000. Believe it or not, Duncan came from a very humble background. You see, he was raised by his grandmother from age 7, following the death of his mother and brother. Unfortunately, Duncan passed away at the age of 77 back in 2010.
His children, Randa, Milane, Dannine, and Scott, inherited a $10 billion estate from their father. Since then. The family’s fortune has more than doubled. That’s thanks to generous dividend payouts and a rise in the stock price pf pipeline behemoth Enterprise Products Partners. Furthermore, Randa, Duncan’s eldest child, is chairman of the board of the company.
