Texas Monthly has been bought by Texas Monthly LLC, a new affiliate of Enterprise Products Company (EPCO), a privately held firm, the magazine reports.

Randa Duncan Williams is chair of Texas Monthly LLC and EPCO. Forbes puts her estimated net worth at more than $6 billion. Williams’ father is the late oil billionaire Dan Duncan, founder of Houston-based Enterprise Products Partners.

The purchase comes less than three years after the magazine was sold to Genesis Park, a Houston-based private equity firm founded by Paul Hobby, whose father was a Texas lieutenant governor and whose grandfather was the state’s governor.

“I have been an avid Texas Monthly reader since I was a teenager,” Williams said in a statement.

“She wants to own it forever,” said Texas Monthly president Scott Brown.
