When you buy something at the store, turn on the television, or eat a meal, you interact with numerous family businesses and contribute to countless family fortunes - perhaps without even realizing it.
Some of the most well-known, wealthiest names in goods and services are established entities that have been around for decades. The historical descendants who inherited those company fortunes may have picked up the reigns of their ancestors' business, or perhaps they just sit back and reap the rewards of their families' success.
Either way, the descendants of billionaires often get to be magnates in their own time. The children of the rich may not be instantly recognizable, but their families pull in some of the biggest paydays around.
Forrest Jr., Jacqueline, and John Mars each inherited 1/3 the fortune amassed from decades of selling M&Ms, Snickers, and Milky Way bars when their father and Mars candy founder, Forest Mars, Sr., passed in 1999.
By the time Mars Sr. passed, the Mars, Incorporated empire extended far beyond confections to other food products and consumer goods
Forrest Jr. passed in 2016 with an estimated worth of about $22.6 billion. Jacqueline narrowly avoided jail time after killing an 86-year-old woman in a 2013 car accident. In 2018, she and her brother are each worth almost $24 billion.
