Clara (The Ghost House)
From Tardis Wiki, the free Doctor Who reference
Clara was a human maid who lived in Ealing in 1884.
She lived in a Victorian house that swapped places with the O'Brain's house from 2009. There she worked for Charles Burden, his wife Beatrice and their daughter May. When the house was placed into the correct time again, she lost her memories of the swapped houses. (AUDIO: The Ghost House)
