Hi BM
I just checked the Qld CD and found Elizabeth's death - father given as James Neill, no mother but the date you have given for John does not exist. The only John from 1909 was June 22, John Patrick Murray
(They certainly lived long lives

)
There are some siblings for John Jnr born in Qld - Do you have them?
James Oswald 1871 Harold 1867 Margaret Dundas 1866
Given that last name, there is a John Murray death registered 11 May 1907, parents James Murray and Margaret Dundas. Have to go out - I'll look for these names in the census this evening.
