Granny Campbell arrived in the village in July 2017 after learning that her granddaughter, Courtney, was pregnant. She was insistent on Courtney returning to Scotland to move in with her, but Courtney refused. Granny Campbell returned a few months later, lying that Courtney was suffering from pre-eclampsia, and held her captive in the flat without the ability to use her wheelchair. After Courtney went into labour, Granny Campbell disallowed her boyfriend Jesse Donovan from visiting Courtney at the hospital.
Following the birth of Iona, Granny Campbell manipulated Courtney into believing that she was an unfit mother. Courtney ended up believing her, and asked Granny Campbell to adopt Iona. However, Glenn Donovan threatened Granny Campbell and forced her to leave the village. In August 2018, Granny Campbell became the guardian of Iona when she was taken from Courtney by social services, but Courtney ended up getting her back.
