Damien Bendall, aged 31, of Chandos Crescent, Killamarsh, is charged with the murders of 35-year-old Terri Harris, her son John Paul Bennett, 13, her daughter Lacey Bennett, 11 and Lacey’s friend Connie Gent, 11.
He is remanded in custody and due to appear at Derby Crown Court this morning.
A provisional trial date of March 1, 2022, has been set but as yet no pleas have been entered.
Bendall was charged after police discovered four bodies at a house in Killamarsh in September after being called over safety concerns.
Terri, the woman he is accused of killing, had recently moved to Killamarsh with her children from Woodhouse in Sheffield.
Connie still lived in Woodhouse and had been on a sleepover when she died.
