Thanks everyone for your input.
I have found a William Richard Kennett in the New South Wales Police Gazette in 1907. He is at Creasey's Hotel in Parramatta. He then aquires a publican licence at Toowoomba, Queensland, in 1908, then 2 more pubs at Ipswich, Queensland, until 1913. In 1914 there is a W.R. Kennett storekeeper at Sandgate, Queensland, selling up and moving to England. It is only an unproven theory, but explains why there is no death for him anywhere in Australia, given also that I can only find 3 William Richard Kennetts in the entire country. Him, his father, and a nephew in S. A.
The dates all fit and my gut feeling is this is him, but cannot prove it.
Thanks again
Regards
Lorayne
