May Burden
From Tardis Wiki, the free Doctor Who reference
May Burden was a human girl who lived in Ealing in 1884.
She lived in a Victorian house that swapped places with the O'Briens' house from 2009. She was the daughter of Charles and Beatrice Burden. She had an older brother, Jack Burden, who died of scarlet fever.
In November 1884, May fell through the crack in time to 2009 and left her worried parents behind. Later her mother Beatrice also came through the crack in time. Skak helped Beatrice and May to get back to their own time. When the house was placed into the correct time again, she lost her memories of the swapped houses. (AUDIO: The Ghost House)
