I have gotten a dead end on my Great Great Grandfather - Patrick Donovan. Apparently is wife's name was Nellie Donovan. I do not know if they lived in Australia, America or Ireland.

Their son is Charles E Donovan who married Ivy May Vincent in Sydmey Australia.

There is a rumour that Charles made his parents name up, and is actually of Aboriginal decent. But I am not sure.

It would be great if anyone has any ideas...
