Sandra Haddon was Lily Haddon's daughter and Martha Longhurst's granddaughter. In 1960, Martha went into the Rovers Return to buy a packet of crisps for impatient Sandra, who had fallen and hurt her knee. According to Martha, Sandra had been eating crisps before she could talk.

Sandra was played by Jennifer Moss in Episode 2 (14th December 1960), to give her experience of live television before making her debut as Lucille Hewitt two episodes later. Sandra didn't appear in the episode, but her voice was heard.
