I am convinced that my father existed but that his parents did not. Oh I do know their names - John and Mary(ne Darcy)and that they married in Maryborough Queensland on 28th August 1875, but then they vanished.

They didn't exist before the marriage and Mary didn't appear again until she died in Brisbane on 14th August 1921. I contacted the Maryborough Historical Society and they found reference to 20 John Halpins but none of the ages matched the one I am looking for. They also found 4 Mary Darcys but once again the ages do not agree.
If these two people (if they existed) were criminals could not have hidden more perfectly. So much so that I am starting to believe that I will never find any other ancestors.
