Elise (The Haunting of Villa Diodati)
From Tardis Wiki, the free Doctor Who reference
Elise was a French nursemaid tasked with looking after William, the infant son of Mary Shelley. In June 1806, Villa Diodati was busy looking after William when a Lone Cyberman in search of Cyberium invaded Villa Diodati, where the Shelleys were staying. Though the Cyberman spared the infant's life, he killed Elise and her body was found by Mary. (TV: The Haunting of Villa Diodati)
Behind the scene
In real life, the full name of the woman who was the Shelley family's nursemaid was Elise Foggi. She was still alive in 1820, by which time she had been discharged by the Shelleys and had become involved in a scandal within Mary Shelley's family.
