Thanks, but I already have a picture of his unmarked grave plot from the lovely lady that was auditing the cemetery; I spoke to her via Skype. I also have all the newspaper cuttings about him at the time of his death.
I have the details of his death, where, when, why and the fact he was buried the same day he died, all of which was provided to me via Skype. It was also noted that on his paperwork it stated he had two living issue, hence my query about why his property never went to them, both of whom are now deceased.
There are no probate records for him in the NT, a search already having been conducted, so I was referred to the SA records.
Thank you for your post, I will Skype the SA courts at some point.
