Samuel Hunter and Caroline North were my great-grandparents on my mother's side. Their son, William Hunter was my mother's father.
We didn't know much about Samuel as he seemed to have been dropped from family history (William died when mum was 6, and Caroline died in the Spanish flu epidemic), mum seems to think because of the Asylum. Mum had a copy of his death certificate and coroner's report which a Tauranga pathologist looked at - thought poor Samuel had had a brain tumor.
Mum is 91 now and her memory isn't so flash, somewhere in her boxes is quite a bit on family history.
