Peggy Garratt

 and her husband Stan lived in Nottinghamshire. They had a son named Neville.

In 1967, Peggy collided with the Fifth Doctor and, in the confusion, came away with a necklace the Doctor had stolen. When two warring alien races came to Earth to retrieve the necklace, she helped the Doctor and Turlough get the necklace to the TARDIS. After the Doctor and Turlough left, drawing the aliens with them, Peggy found that the Doctor had left the necklace for her, so that she could wear it in one week's time and have her picture taken in the newspaper — the event that had brought the Doctor to Earth in the first place.
