Edith Thompson

 was the scullery maid for the household of Edward Grove in 1906. She later was the cook for Charlotte Pollard's family. She committed suicide when she heard that Charley had died in the crash of the R101, as Charley was the only person who cared about her. Edward Grove used this to his advantage when the Eighth Doctor and Charley landed in 1906. (AUDIO: The Chimes of Midnight)
