Following Enoch's death in 1901, his sole child, a son Aaron, born in the 1870s, had Southfork Ranch signed over to him and carried on his father's legacy.

Aaron and his wife Barbara had two children: son Garrison and daughter Eleanor, who eventually became known as Miss Ellie.

In 1936, Miss Ellie married Jock Ewing, who helped Aaron save Southfork Ranch from bankruptcy.

Garrison dated and later married Cherie Simmons (in the television movie The Early Years), but it is unknown if the couple had any children.

However, Jock was so upset over J.R.'s remortgaging of Southfork Ranch that Bobby stepped in to help run Ewing Oil.

J.R. had gotten word that problems were escalating in Asia so he decided to sell 75% of the Asian leases to members of the Cartel (a small group of independent oil companies who work together for mutual benefit) - Seth Stone, Jordan Lee, Wade Luce and Andy Bradley - as well as banker Vaughn Leland, all bought shares.

Bobby moved very fast and was eager to prove he was smarter and better than J.R. at running Ewing Oil, but encountered numerous obstacles in the business community.

Bobby made several business decisions including changing banks and selling Ewing assets to buy a refinery, all while not consulting Jock or J.R. about any deals.

Bobby eventually pulled the deal off via a loan but had a terrible fight with Jock and decided to quit Ewing Oil, and later became a state senator.

After his wife Sue Ellen left Southfork and moved in with Dusty Farlow at Southern Cross Ranch in San Angelo, J.R. began stock-piling all of the oil that went to Farlow Refineries as a way to force Sue Ellen to come back to him with their son, John Ross.

Just prior to this, as an interim measure in his absence, Jock gave his family the power to control the company with voting shares which were divided as follows: When J.R.'s plan to ruin the Farlows backfired, Miss Ellie stepped in to stop the destruction of Ewing Oil and made a deal with Clayton Farlow.

Furious at J.R., she persuaded the family to vote with her to have him fired as president, but changed her mind at the last moment as nobody would be able to take his place at the time.

However, when Ellie later learned that J.R. had used Ewing Oil to ruin Cliff Barnes (resulting in his attempted suicide), the family voted unanimously to remove J.R. as president and Bobby took over again.

J.R.'s route was to over-pump oil with a special variance from the OLM (which he obtained through blackmail), refine it and open a chain of cut-price gas stations.

Bobby and Pam divorced; and Cliff and Pamela's mother, Rebecca Wentworth, died in a plane crash in an attempt to stop J.R. from winning.

Ownership of Ewing Oil was now as follows: In 1984, Bobby was shot at the office by Katherine Wentworth, Pam's half-sister who was in love with him.

During his recovery, Donna Krebbs stepped into his place, much to the annoyance of J.R. Jamie Ewing, Jock's niece, turned up at Southfork Ranch from Alaska, where she had been working in the oil business.

The Ewing family agreed and Jack took Ray, Bobby and J.R. to meet a man called Wally Wyndham.

An Ewing employee named Scotfield lost his job and, in his anger, he blew up a well, was later arrested and committed suicide.

As April agreed to sell her share back to J.R. and Bobby, the company was now divided as follows: The same year, J.R. wanted the price of American crude to rise and he met with mercenary B.D.

In the 1996 TV movie Dallas: J.R. Returns, Cliff Barnes sold Ewing Oil to Bobby and Sue Ellen.

John Ross continues the Ewing tradition in the oil industry while Christopher works on new gas hydrates technology.

When John Ross was attacked while in police custody for the suspected murder of Veronica Martinez aka Marta Del Sol, Christopher signed over exclusive South American rights to his technology to John Ross's former business partner, Vicente Cano.

Vicente's part of the deal was to provide video tape evidence that would clear John Ross.

It is discovered in the season finale that before his arrest for his hand in the fraudulent Southfork sale, Vicente was about to sell off his South American rights to Cliff Barnes.

Cliff's plan was to sabotage Christopher's technology demonstration on the gas rig, causing the state to levy a billion dollar fine against Ewing Energies.

Meanwhile, Governor McConaughy was to seize the Ewings' oil wells via eminent domain, making it impossible to pay the fine.

Emma stole evidence from her father's safe that linked him to working with a Mexican drug cartel and cocaine trafficking.

He showed up in Dallas in the season premiere and stopped the Ewings from selling their consumers division to help pay for the arctic leases.
