Pamela Rebecca is born off-screen in Dallas in 1985, as the daughter of Cliff Barnes and Afton Cooper. At the time of Rebecca's birth, Afton had left Dallas, and Cliff wasn't aware of her existence until 1989, when she appeared in the season 12 episodes "Yellow Brick Road" and "The Sound of Money". As Afton didn't want to acknowledge Cliff as the father of Pamela, they soon leave Dallas again.
