While 2020 has been a nightmare financially for many, some locals have cashed in. One example is Houston's Duncan family, with a net worth of $22 billion, who once again appear on the annual Forbes ranking of America's richest families. (The Duncans come in at No. 11 on the Forbeslist.)

The four children of pipeline mogul Dan Duncan — Randa Duncan Williams, Milane Frantz, Dannine Duncan Avara, and Scott Duncan — inherited a $10 billion estate from their father when he died in 2010. The net worth of each heir exceeds $5 billion.

Randa enjoys the highest profile among the four Duncan siblings. She is chairwoman of Houston-based Enterprise Products Partners, the pipeline giant founded by her father, and owns Austin-based Texas Monthly magazine.

Elsewhere in Texas, The Walton family once again reigns as the richest family in the U.S., according Forbes. Their net worth: $247 billion. In its 2020 budget year, Walmart racked up revenue of $524 billion — and the company continues to rack up riches for heirs of the retail giant's founders.

That $247 billion sum represents close to half of Walmart's annual revenue and is equivalent to the size of Chile's economy.

The net worth of Fort Worth billionaire Alice Walton, the only daughter of Walmart founder Sam Walton, accounts for a little over one-fourth of the family fortune. Forbes estimates she's worth about $68 billion, making her the richest resident of Texas and the richest Walton heir. If Alice Walton were a family unto herself, she'd rank as the fourth wealthiest clan in the country.

Descendants of Sam Walton and brother Bud Walton own about half of Walmart's stock. Forbes says the stock generates more than $700 million in annual dividend income for the family.

Alice Walton isn't the only Texan who's a member of the Walton dynasty. Ann Walton Kroenke, one of the two daughters of Bud Walton, lives on a 535,000-acre ranch about 50 miles northwest of Wichita Falls. She is worth about $9.1 billion and is married to sports and entertainment titan Stan Kroenke, who's worth an estimated $8.3 billion.

While all of the Waltons don't live in the Lone Star State, members of four of the country's other wealthiest families do.

At No. 15 among the country's wealthiest families is the Butt family, with a net worth of $17.8 billion. Charles Butt is chairman and CEO of the H-E-B grocery chain, based in San Antonio and parent company of Dallas-based Central Market. Butt, grandson of H-E-B founder Florence Butt, and three relatives — sister Mary Butt Crook and two nephews — own H-E-B. The company's annual sales are around $28 billion.

The Hunt family, whose members are descendants of oil wildcatter H.L. Hunt, sit at No. 18 on the Forbes list with a net worth of $15.5 billion. The richest among them are billionaires Ray Lee Hunt and W. Herbert Hunt, both of Dallas.

Rounding out the Texas contingent on the Forbes list are members of Fort Worth's Bass family. The Basses hold down the No. 30 spot with a net worth of $10.8 billion. The four Bass brothers — Sid, Edward, Robert, and Lee — each inherited $2.8 billion from their oil tycoon uncle Sid Richardson after his death in 1959. Robert is the wealthiest of the foursome.
