Hi Benlewis, I am new here.
I have stumbled across your thread by accident. I am looking for a Mary Delury who appears on the same 1901 Census as your relation. I'll be polite and say she was a guest at the Devon and Exeter reformatory school. She is my Great-Grandmother.
I know all about her from the time she got married to when she died aged just 35, and even tracked down where she is buried but I am struggling to find much as a single woman. I can't even find a birth certificate despite her being born in Barking (according to this census and the 1911).
Just thought I'd ask if you have had any joy finding records for the reformatory because I'm just drawing a blank?
Finally, as another coincidence, Mary spent her adult life in Woolwich (I live in Bexley) so our ancestors followed a similar path.
