Florence was born in 1870 so there is a significant difference of 16 years - sort of "toy boy", I dont see that as an issue bit we might consider it in the "big picture".
How do we establish a 1931 address -
If there is "grave finder" could we find a crematorium that would have existed after 1931, and who knows how far- Perhaps if Patrick FLANAGAN had war service he may be recognised by the Australian war graves commission. I know that my father was a POW and although buried privately there is memorial plaque in the war graves section of the cemetery. I applaud your involvement.
