Helen Sinclair's grandmother

From Tardis Wiki, the free Doctor Who reference

Helen Sinclair's grandmother enjoyed baking, reading stories at night and spoiling her, Harry and George. One day, she came back from the hospital and told them her family that she was ill, later telling them that it was terminal. She had died by the time that Helen joined the Eighth Doctor and Liv Chenka in 1963. (AUDIO: Ship in a Bottle)
