Just found out:
Papers Past; Evening Post; 6 August 1887; Dens of Infamy in Wellington.
The Alfred mentioned in the last paragraph is my maternal grandfather's father.
Charles: My great great grandfather.
Grace and Maud: My great great aunties.
This was the first of my mother's family to come over from Whitechapel, London. It's a good thing they did as Grace and Maud would have been prostitutes in the immediate vicinity of Jack the Ripper.
