Hi Alison, Thanks for your reply!!.
Recently I have just found out some new information about all the births for their children and they were all born in Australia. Mary Fullerton also had been born in Australia and not Scotland and died in Australia.
So now I am just looking for William Warr's information. Going by what I have heard about his death certificate, it states he was born in Oxford, UK. He was 71 years old when he died in 1910. So he was born approx 1839. As far as I know there are no parents listed on his death certificate.
I do not have much information to go on until I get his death certificate.
