Connally's main legal customers were the Texas oil wealthy person, Sid W. Richardson and Perry Bass, who was Richardson's nephew and partner, both of Fort Worth. Richardson's family dynasty business at the time was estimated at $200 million to $1 billion. Under Richardson's custody, Connally had experience in many enterprises and received tips on real estate purchases. The work required the Connallys to relocate to Fort Worth. When Richardson died in 1959, Connally was named as the profitable position of co-executor of the estate.
