Barbara Smith

Barbara Smith (née Wilson) was the mother of Sarah Jane Smith and the adoptive grandmother of Luke Smith and Sky Smith.

Timeline 1
Barbara and her husband, Eddie Smith, died on 18 August 1951, the day of the Foxgrove village fete, when they drove off in their car, leaving their three-month-old baby behind in her pram. The infant Sarah Jane was subsequently raised by Eddie's sister Lavinia.

Timeline 2
Sarah Jane and her son Luke travelled from 2009 to meet Barbara and Eddie. Sarah Jane decided to save them by deactivating their car so they would not be able to leave. However, while this change in and of itself had no major effect on the timeline, meddling with history near an unstable rift in time caused the rift to open, allowing the Trickster to fully materialise on Earth and conquer the world.

Timeline 3
After Sarah Jane returned to 1951 Foxgrove from the alternate timeline her parents' survival had created, Barbara soon worked out who Sarah Jane was after hearing her real name and witnessing the Trickster begin to manifest. Barbara and Eddie decided to restore the timeline by sacrificing themselves to save Sarah Jane's world. (TV: The Temptation of Sarah Jane Smith)
