<Tr> <Th> Nieces </Th> <Td> Pamela Rebecca Barnes </Td> </Tr> <Tr> <Th> First cousins </Th> <Td> Jimmy Monahan </Td> </Tr> <P> Pamela Barnes Ewing is a fictional character from the CBS primetime soap opera, Dallas . Pamela is portrayed by actress Victoria Principal, first appearing on the show in the first episode, entitled "Digger's Daughter", which was first broadcast on April 2, 1978 . Dallas follows the trials of the wealthy Ewing oil family in the city of Dallas, Texas, which Pam has married into . Principal played Pam until the end of the tenth season of Dallas in 1987, when the character crashes into a truck carrying butane and propane and her body is severely burned . After this, she is briefly played by actress Margaret Michaels in an attempt to write the character out . Pamela's storylines in season 1 focus on her relationship with her new husband, Bobby Ewing (Patrick Duffy), and her fight against the considerable suspicion and hostility from within the Ewing family, due to Pamela being a member of the Barnes family . Pamela's love for Bobby remains a strong character trait throughout her tenure on the show, noted for its similarities to Romeo and Juliet, with two people from hostile families falling in love . </P> <P> In the early years of Dallas, Principal took certain measures in her personal life in order to add depth to her character . She initially was very distant from the cast and they assumed she didn't like them . Series producer Leonard Katzman confronted her about the issue and she said, "I like everybody . It's just that I want to feel like an outsider, like Pam Barnes does, being married to a Ewing ." Principal also took to other ways of improving her character, such as taking voice lessons to perfect a Texas accent . Her relationship with Patrick Duffy's character, Bobby, was a central component to the show, and when Duffy returned to Dallas in 1986, after being killed off a year earlier, the entire previous year had been written off as Pam's dream . </P>
