The "novel" Ralph White came into contact with Margaret White in 1960 and married her two years later. He was also a fundamentalist Christian and believed, as did his wife, that all forms of intercourse — even in marriage — were sinful. Several months before his daughter Carrie White was born, Ralph died in a grisly construction accident.
The 1976 film version of Ralph was only mentioned by name during the movie. Carrie revealed at one point, that "he ran away." Margaret tried to convince her child, that her husband was tempted by the devil and taken away. Carrie, on the other hand, saw the devil as another woman, whom Ralph ran away with.
Twenty-three years later, Ralph was mentioned again by a woman named Barbara Lang, mother of her daughter named Rachel Lang, the main protagonist in The Rage: Carrie 2. Barbara said, that Ralph was the father of Rachel. Rachel herself possessed similar powers to Carrie and was also considered an outsider--although Rachel was more independent and outspoken than Carrie. Meanwhile, a grown Sue Snell--the only survivor of the Bates Senior Prom disaster--tried to inform Rachel, that she and Carrie were somehow related, since Ralph was father to both.
