Murphy is her birth name - no birth certificate but stated on her marriage certificate age 18, (permission given by an adult cannot find a relationship, married in NZ, have the Certificate and Intention to marry, No clues). Married name, Minton, separated 1880; 16 years difference in age with husband and taking a long bow suspect she left him (and her five children) for someone else, so assume she lived under someone else's name; there is no record of her after the death of the infant. The only clues I have are where she was living at the time (20 Exeter place) and the name of the infant, Maude Alice a total difference from the other children's names which were rather posh, and Mrs Megan witness to the birth. The one Mary who showed up in Newington Asylum was a Mary O'Neil - note the spelling - and there are a couple of references to same in SMH. That's all I have
