Following the death of Sonia's mother when she was just aged two, Elli took in her granddaughter to raise her when Sonia's father played an almost non-existent role in her life. It is assumed that Sonia's father is Elli's son, as Sonia shares a surname with Elli.
Sonia was the victim of the 1967 train crash on Coronation Street. Elli Jane, now aged about 70, turned up to look for her granddaughter, and Stan Ogden consoled her, and the news was later broken to her of Sonia's death. Minnie Caldwell attempted to comfort Elli at the Rovers Return, but with little result.
Full Name: Elli Jane Peters
Children: Mr Peters
Grandchildren: Sonia Peters
