Surrey

From TARDIS Index File, the free Doctor Who reference.

Surrey was a county of England. The early events of The Visitation took place here, although Heathrow was later absorbed into Greater London in 1965.

Paul McGann, Katy Manning, Bonnie Langford and Nicola Bryant were all born in Surrey. The Surrey Heathland was used to double for the Peak District in Derbyshire in Doctor Who and the Silurians.
