O'Connor, John, Maria & Berna. Relatives in Melbourne, Aust.

I am seeking any information on two cousins of my father, who I knew as Maria & Berna.Neither married and lived for many years in Footscray near the train line (a goods yard I think).They would be quite elderly now.My father (now dec.) is John Mervyn O'Connor and they had a brother also named John O'Connor.I believe he died at an early age leaving a wife and young family.Have not had any contact with them since the mid-70's.Would love to find them again if they are still alive or any of their immediate family.
