Hi Wivenhoe
Answers to your questions below.
The children were aged 0 to 12 when their mother died. She died of uterine hemorrhaging according to the death record.
I agree unlikely that father could not look after them. From information above William (b1866) was sent to the Caversham Industrial School before the death of his mother. So he was possibly running wild? Or hard to manage locally!
The Parliamentary report of 1882 suggests the youngest (Joan) was in the care of a local lady after the death of John Johnston. One could guess the same lady was helping before his death. But that is a guess.
A person whose research encroached on the family of Jane (b1864) has indicated she was looked after by the Clifford family. Can I prove that? No. Jane (who became Jane Forno) did name one of her children Clifford which of course could be a coincidence.
The best I can do is assume the eldest two (Elizabeth and Martha) finished their schooling locally with support from local families (Cliffords again?).
Who looked after William, Catherine and Mary is a mystery. I have unsuccessfully chased school records. We now know they were in the Caversham Industrial School shortly after John Johnston's death.
The wedding record I have is a transcription written in one hand so cannot tell whether they were literate.
The researcher mentioned above has indicated that
"I believe the children were raised by a Mr Clifford, possibly a post master, which is where the Clifford name comes from.
Other than that - only John Johnston (Length of Residence for Intention to Marry- 9 years, age 35.) (Elizabeth Bell L of R for Intention to Marry - 8 months, age 25.)"
Spades has indicated the possibility of confirming that.
I do not have a cause of death or a death cert for John Johnston.
Any hints would be greatly appreciated.
As an additional piece of information, Peter McGill, who was discharged with John Johnston at Port Chalmers seems to be the same person who died at Milton 21 October 1894 aged 68. He was a native of Stonykirk, Wigtonshire, Scotland according to his gravestone.
