Jennifer Buckingham

Lady Jennifer Buckingham was a nurse and ambulance driver who served in the Women's Volunteer Reserve during World War I. She was abducted by the War Lords and hypnotised into participating in their simulated version of the war. She and Lieutenant Jeremy Carstairs broke their condition thanks to the Doctor, and they assisted him in fighting against the War Lords. She, like all the survivors of the War Lords' victims, was returned home by the Time Lords. (DW: The War Games)

The Doctor met Lady Jennifer and Lieutenant Carstairs again in 1915, though they had no memory of meeting him before. He then helped them and Winston Churchill escape from the Players who had captured them.

Jennifer Buckingham and Jeremy Carstairs eventually got married. (PDA: Players)
