J.R. - unscrupulous and unhappily married to Sue Ellen Shepard (Linda Gray), a former Miss Texas - was frequently at odds with Bobby, who had the morals and integrity that J.R. lacked. Middle son Gary was Miss Ellie's favorite as he displayed Southworth traits; however, Gary had been in conflict with both Jock and J.R. since childhood and was dismissed as a weak link. While still young, Gary had married waitress Valene Clements (Joan Van Ark), who produced the first heir, the petite and saucy Lucy (Charlene Tilton). Years prior to the series beginning, J.R. had driven Gary and Valene off Southfork, leaving Lucy to be raised by her grandparents.
