but it could be possible that he gave the correct parents, even if he'd changed his name.
On HIS Death Registration??? Nobody else would know the names of his parents (who had died back in England). He would just be another Joe Bloggs, or whatever name he had chosen, with unknown parents. I am sure that there must have been many such individuals in Australia at that time. I have searched for his real name and drawn a blank. I have no idea what other name he may have chosen. He is unlikely to have used the name of somebody closely related to him. I probably have more chance of winning the lottery
His daughter, who married just before his departure from England, also posted requests for news about him over 30 years later in Sydney and Adelaide publications (that I have found). Perhaps she put similar requests in other towns/countries that I have not found.
