Margaret Hayhoe
From Tardis Wiki, the free Doctor Who reference
Margaret Hayhoe was Lizbeth Hayhoe's sister whom she did not visit especially often due to her work at Torchwood One. (AUDIO: Madam, I'm)
When Lizbeth was pulled out of time, she wondered about the funeral that Margaret must have held for her and believed that she would not have invited any of the Wrens whom she looked after during World War II. She told Andy Davidson that she would turn Margaret into glue if she had destroyed her dog. (AUDIO: Ashenden)
