It has been an interesting series, particularly as it ties in with my own research.
Regarding the cholera epidemic, one of my great grandmothers died of cholera in the infirmary of the Brownlow Hill Workhouse. The site is now occupied by the Catholic Cathedral.
The female penitentiary on Falkner Street was for fallen women, when the red light area moved to this area from Lime Street. One of my other great grandmothers was living in Smithdown Lane. She'd moved there from St Helens as a young woman and was probably on the game. She moved back to St Helens and was almost certainly sent to prison for three months for co-managing a brothel there.
I could give them a lot of good stories for the next series..
