Hi, this is a long shot but I wonder if someone would look up a Charles J Davis. I'd certainly appreciate anyone doing this for me.
He was living in Darlinghurst when he died and something I read made me thing the Waveley cemetery would be the most likely cemetery. If this isn't so then please ignore this post.
His wife was Georgina. He had a son. I think it more than probable he has a proper headstone.
It is more than probable also that he was Roman Catholic.
I suspect he died sometime between 1912 when he married and 1930 but this is merely supposition. I can't find him on any war record.
Another possibility is that Davis was mistaken for Davies.
Sorry I can't be more specific than that.
