Biggest wealthiest families in the world

Since, we are talking strictly about families here so I would exclude some individuals.

The Walton Family
*Owner of Walmart and Arvest Bank Group
*Net Worth: $190.5 billion as of 2019

The Walton family is an American family, whose collective fortune makes them the richest family in the United States of America and the richest non-royal family in the world.

The majority of their wealth derives from the heritage of Bud and Sam Walton, who were the co-founders of the world's largest retailer, Walmart. The three most prominent living members (Jim, Rob and Alice) have consistently been in the top twenty of the Forbes400 since 2001, as were John (d. 2005) and Helen(d. 2007) prior to their deaths. Christy Walton took her husband John's place in that ranking after his death.

As of December 2014, the Waltons collectively owned 50.8 percent of the company.

In 2018, the family sold some of their Walmart stock and now owns just under 50%.

In October 2019, the annual Sunday Times Rich List indicated the Walton family's wealth is at $US201.4 billion

Bernard Arnault Family
*Owner of LVMH
*Net Worth: $117 billion as of January 2020

French national Bernard Arnault is the chairman and CEO of LVMH, the world's biggest luxury goods company. The company owns some of the biggest brands on earth including Louis Vuitton, Hennessey, Bulgari, Marc Jacobs, Dior, Sephora, and many more.

An engineer by training, Arnault's business chops became apparent whilst working for his father's engineering company, Ferret-Savinel. He converted the company to a real estate company in 1976.

Arnault acquired luxury goods maker Financière Agache in 1984, eventually selling all of its holdings other than Christian Dior and Le Bon Marché department store. He became chairman of the board of LVMH in 1989. His own investments are broad, including technology concerns and yacht companies.

The Koch Family
*Owner of Koch Industries
*Net Worth: $110 billion as of January 2020

Koch Industries was founded by Fred Koch in 1940 and is majority owned by his sons, better known as the Koch Brothers—David and Charles, with each owning 42% of the company. David, 79 years old, stepped down from his role with the company in 2018 due to health issues, while Charles, 83, remains Chairman and CEO.

Fred Koch: Father and Founder

At the age of 27, a chemical engineer by the name of Fred Koch developed a new and more efficient process for turning crude oil into gasoline. An MIT graduate, Fred had invented a new method of refining gasoline from viscous and common heavy oil. After a string of lawsuits from Universal Oil Products, which had patented and was licensing a similar technique, Fred brought his innovation to the Soviet Union 1929. He returned to America shortly after to start a family.

Koch Industries is the second-largest privately held company in the U.S., per Forbes annual rankings, generating $110 billion in annual revenues. This has helped position the Koch family as the second richest family in the world, behind only the Walton family (Walmart owners). The Bloomberg Billionaires Index puts the Walton family fortune at $152 billion, while the Koch family is worth $99 billion.

Al Saud - Saudi Royal Family
Estimated Wealth: $100 billion
*Owner of Saudi Aramco
*Net Worth: $100 billion as of January 2020

The House of Saud, the Saudi royal family has a monarchical history extending back nearly a century. The family's massive fortune, estimated at $100 billion, has grown thanks to decades of payments from the Royal Diwan, the king's executive office. Ties with Saudi Aramco, the world's most profitable company and a behemoth of the oil industry, ensure that the Saudi royal family continues to accumulate wealth. It's difficult to accurately assess the wealth of the House of Saud, in part because the family contains as many as 15,000 extended members, many of whom have founded businesses, received government contracts and more. Though, am not sure about this as their rightful owner is the Government of Saudi Arabia.

The Mars Family
* Owner of the Mars Chocolate Empire

The Mars family sits on top of a delicious empire. They're the heirs to the candy throne that is Mars Inc., maker of Snickers, Mars Bars, Milky Way Bars, Twix, M&M's, and more — not to mention a portfolio of PetCare products, drinks, and gum, among others.
