Susan Foreman's grandmother

Susan Foreman's grandmother was the grandmother of Susan Foreman and partner to the First Doctor.

In November 1963, when Ian Chesterton and Barbara Wright barged their way into the TARDIS, the Doctor was forced to take them against their will and make a quick escape because Susan's grandmother had entered 76 Totter's Lane with the intention of getting the Doctor to perform her housekeeping. After the TARDIS had dematerialised she angrily proclaimed him a rascal. (NOTVALID: An Unearthly Child: The Unscreened Edition)
