I don't want to split hairs (but I'll do it anyway!) I'm sure her name was Kirsten, but whenever it's asked in quizzes people always say Kristen. Can anyone confirm which is right... Please!
Definitely Kristin (Kristin Shepherd). Played by Mary Crosby (daughter of Bing and Kathryn Grant) She was in Dallas from 1978 - 1981. She shot J.R. in episode 54 entitled "A house divided"
