Marguerite McQueen is the daughter of Queenie McQueen, the widow of an unnamed man and the mother of Victor and Breda McQueen.
Marguerite married a pig farmer, and they had at least two children together. Her husband was an alcoholic that would beat Marguerite and Breda. When keeping him captive, Breda told Louis Loveday that her father died after coming home drunk one night and fell down the stairs resulting in a head injury. It is revealed the next year that Breda murdered her father, shooting him in the head with the bolt gun that he used to kill the pigs.
