Mary Jane 'Black Kelly' or 'Ginger' Kelly was born in Ireland. After living in Wales for a while, she moved to London where she got married. Her husband was then unfortunately killed in an accident, so she turned to prostitution and working in a brothel as her source of income. She lived with another man for awhile, until they broke up because he found out that she was letting other prostitutes sleep at their house. Mary Jane was young and pretty unlike the other victims, at only twenty-five years old.
Mary Jane was murdered on the 9th of November, 1888. She was seen just the day before drunkenly singing in the streets. At 10:45am her landlord came into her room on Dorset Street to demand her rent money which was six weeks late, but found her dead and mutilated body on the bed, with her clothes folded neatly next to her. Her dead body was described as 'more like the work of the devil than the man', suggesting she was yet another victim of Jack the Ripper.
Mary Jane was the last known victim of Jack the Ripper.
