Agnes Havisham was born under another name. She used "Agnes" as a pseudonym for Torchwood. Her mother was Scottish and an alcoholic. Her father wanted a boy and trained her from a young age to use guns. Neither were particularly pleased with her choice to join the Torchwood Institute. She also had a younger sister named Tilly, but Agnes was unable to find out what happened to her after Agnes became Torchwood Assessor.
