Rocking unimaginable wealth, the 25 richest families in America have a combined fortune of over $940 billion – around $30 billion more than the GDP of the Netherlands. From the Gallos to the Waltons, read on to discover the mind-blowing net worths of the wealthiest dynasties in the US, according to data from Forbes and Bloomberg.

Partial to a drop of Californian wine? Chances are you've drunk this family's goods. In 1933, brothers Ernest (pictured) and Julio established the famous E & J Gallo Winery. Younger brother Joseph started up a cheese-making business in 1979 but fell out with his siblings when they sued him for using the family name. Now run by the brothers' 17 children and grandchildren, the wine and cheese businesses combined have generated billions of dollars.

Brothers John and O. Wayne Rollins went into business in the 1940s, originally starting a broadcasting company to advertise their family car dealership. The company went public in the 1960s and the Rollinses used their ever-growing profits to purchase a variety of other businesses, including pest control company Orkin. Today Rollins, Inc. is a commercial services organization with subsidiaries in the UK and Australia, as well as being the biggest pest control firm in North America by revenue. The Rollins family owns more than 50% of the business and the current CEO is Gary W. Rollins (pictured), O. Wayne Rollins' son. 

The Goldman family's real estate company Solil Management is headed by Jane Goldman, the daughter of late founder Sol Goldman (pictured). The business currently owns more than 700 properties in New York, making it one of the largest landlords in the city. Around 20 family members share a fortune of $13.2 billion.

Dr Homer Stryker (pictured) was working as an orthopedic surgeon in Michigan when he began inventing products for his patients. In 1947 he patented an electric saw that was designed to remove casts without breaking the skin beneath. By the 1960s Stryker had retired from practicing medicine to focus on the Stryker Corporation, the business he set up to sell his medical inventions. Today, his three grandchildren own around 13% of the company, which made $17.1 billion in sales in 2021.

In 1967, S. Truett Cathy founded the fast food chain Chick-fil-A in Atlanta, Georgia. America's third-largest restaurant chain by 2019, Chick-fil-A is currently run by Truett's son Dan Cathy (pictured), who works as chairman and CEO of the company and has a personal net worth of $4.5 billion. Dan's younger brother Donald, known as "Bubba," is vice-president. All told, the Cathy family has a net worth of $14.2 billion.

During the 70s, the late William Bernard Ziff Jr. transformed his father's moderately successful magazine business into publishing leviathan Ziff Davis thanks to niche but hugely profitable titles such as PC Magazine and Car and Driver, which earned the company billions of dollars. The company was sold for $1.4 billion in 1994 and Ziff's three investor sons inherited his fortune when he died in 2006. The image shows heir Dirk Ziff (far right) and his wife Natasha (far left).

Dubbed "The First Family of Soup," the Dorrance family are heirs to the famous Campbell soup fortune. In 1897, Dr John Dorrance (pictured) invented a cost-effective method of condensing soup and eventually gained full control of the Campbell's Soup Company. An estimated 11 members of the Dorrance family own half the company, which made $8.47 billion in revenue in 2021. 

During the 20s, oil man and lucky gambler H. L. Hunt (pictured) – the real-life inspiration for J.R. Ewing from classic TV show Dallas – swapped poker winnings for oil rights, eventually controlling most of the oil fields in Texas. When he died in 1974, Hunt was the richest person in America and left 13 surviving children. His heirs have branched out into hotels, sports, and real estate.

The Du Pont family is the largest and most "old money" family in our round-up. The fortune, which is spread out among a whopping 4,000 family members, began with French immigrant Éleuthère Irénée du Pont (pictured), who founded the gunpowder business that become DuPont in 1802. Over the years, the company has moved into chemicals, inventing nylon, Teflon and Lycra. While the family is longer in control of DuPont, its members own substantial shares in the company.

The Busch family has America's best-known beer to thank for its piles of cash. Patriarch Adolphus Busch (pictured center) started brewing Budweiser way back in 1876. His Anheuser-Busch Company remained wholly owned by his descendants until 2008, when Belgian-Brazilian brewing giant InBev acquired the firm for $52 billion. The fortune is reportedly shared among 30 family members.

Florence Butt started the family grocery store business back in 1905 on the ground floor of her home in Kerrville, Texas. Her son Howard took over in 1919, eventually developing the H-E-B chain of supermarkets. Howard's son Charles (pictured) is the current company CEO, presiding over 300 stores with annual sales of $16 billion. He shares the huge family fortune with just four relatives.

J. Howard Marshall II, who made his fortune from oil, famously married Playboy playmate Anna Nicole Smith in his twilight years and disinherited his eldest son J. Howard Marshall III, creating the mother of all probate battles upon his death. Marshall II's younger son E. Pierce (pictured here with his wife Elaine) received the bulk of the estate. He died in 2007 and left the fortune to his wife and two sons, who successfully fought off challenges from J. Howard Marshall III and Smith's estate.

Like the Gallos and Buschs, the Brown family has made serious money from booze. The clan of 25 owns a majority stake in the Brown-Forman Corporation, the company that produces Jack Daniel's whiskey, Chambord liqueur and Finlandia vodka. The family traces its wealth back to pharmaceuticals salesman George Garvin Brown (pictured), who founded Brown-Forman in 1870.

The original media mogul, William Randolph Hearst, the inspiration behind Orson Welles' Citizen Kane, owned 28 major newspapers and 18 magazines at his peak. Hearst's living descendants, who number around 67 and include the current Hearst Corporation chairman William Randolph Hearst III and model-turned-actor Lydia Hearst (pictured), share the immense family fortune.

Texas native Dan Duncan grew up in poverty, scraping together the cash to found natural gas and oil company Enterprise Products in 1968. A true rags-to-riches story, Duncan's company had an annual turnover of $34 billion when he died in 2010. The gas and oil tycoon's four children inherited the firm and are each worth billions of dollars.

Together with his brother Donald and nephew Steven, Samuel Irving "S.I." Newhouse (pictured) inherited Advance Publications, the parent company of publishing giant Condé Nast, social news site Reddit and a whole host of newspapers including The Star-Ledger. S.I. passed away in 2017 and the $30 billion Newhouse fortune is currently shared among 23 family members. 

The Pritzker family, who number 13 members, made a colossal fortune from shrewd investments in firms such as Berkshire Hathaway, as well as ownership of the Hyatt Hotels Corporation. The hotel group was founded by family patriarch A.N. Pritzker in 1957. The family wealth is shared among his children, including Jay Pritzker (pictured), and grandchildren.

Media conglomerate Cox Enterprises has a wide array of newspapers, radio stations and TV channels in its portfolio and annual revenue of almost $20 billion. Cox Enterprises was founded by James M. Cox in 1898. His five living heirs, who include company chairman James Cox Kennedy (pictured), still control 99% of the firm.

Together with her two siblings, Abigail Johnson (pictured), who has been described as the most powerful woman in finance, owns a 49% stake in Fidelity, the flourishing fund management company started by her grandfather Edward C. Johnson II. The remaining 51% is held by the company's employees. The business currently has a staggering $4.2 trillion in managed assets and Abigail alone is worth $19.4 billion.

Yet more super-wealthy Johnsons. This moneyed clan, which isn't related to the previous family, wholly owns cleaning products company S.C. Johnson & Son. The firm makes around $11 billion a year in revenue and has a portfolio of brands that includes Mr Muscle, Pledge and Ziploc. Pictured is Dr. Herbert Fisk Johnson III, part of the fifth generation Johnsons to lead the company, who is personally worth $3.4 billion. 

Estée Lauder (pictured) founded her eponymous cosmetics company in 1946. By 1960, the company's wares were being sold all around the world. Lauder created Clinique, the first dermatology-driven beauty brand, in 1968, and Estée Lauder now has a portfolio of around 30 brands, including La Mer, MAC, and Aveda. Six heirs, all Estée Lauder board members, share the huge family fortune.

Christmas must be an opulent affair within the Cargill-MacMillan clan: the family boasts eight billionaires and a total of 90 members own 88% of the agribusiness firm Cargill Inc. Founded in Iowa in 1865, Cargill is now one of the biggest private companies in America with annual revenue of around $114.6 billion. Pictured is the late company patriarch Cargill MacMillan Jr. 

When Forrest Mars Sr. died in 1991, the confectionery tycoon bequeathed Mars Inc. to his three children: Jacqueline, Forrest Mars Jr. and John Mars. The Mars siblings have complete control over the candy and pet foods company, which owns a multitude of popular brands and has an annual turnover of around $40 billion. John Mars is pictured here receiving an honorary knighthood from Queen Elizabeth II in 2015. 

Fred C. Koch founded the oil refining company that became Koch Industries in 1940 and passed it on to his four sons upon his death in 1967. The company pioneered a new refining method, which generated billions of dollars over the years. Charles (pictured) and David successfully sued their brothers William and Frederick for control of the firm during the 80s and 90s. David passed away in 2019, while Charles currently has a personal net worth of $59.8 billion. 

The wealthiest family in America by almost $140 billion, the Walton family controls almost 50% of supermarket behemoth Walmart, America's largest business in terms of revenue, with an annual turnover of $559 billion in 2021. The fortune is apparently shared between seven family members, the living heirs of brothers Sam (pictured with his wife and children) and James, who co-founded the ridiculously successful family company in Arkansas in 1962.
