Ralph White (b. Oct , 23 , 1930; 'd. Feb 1963) is the father of Carrie White and was married to Margaret White. He was not involved in raising Carrie, although all versions strongly suggest that it was through his blood that Carrie gained her powers.
The "novel" Ralph White was a construction worker who came into contact with Margaret White in 1960. He was also a fundamentalist Christian and believed, as did his wife, that all forms of intercourse — even in marriage — were sinful, as opposed to many other Christians who believe martial sex is something to be nurtured and enjoyed. Nevertheless, two years after meeting Margaret, he married her. After one night of raucous drinking with the men, Ralph came home and heated by the booze, seduced Margaret, resulting in the forthcoming pregnancy of his daughter. This version also gives explicit reason for his absence: Carrie was a posthumous child; Ralph having died in a grisly construction accident prior to Carrie's birth.
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.
