Potter Family from Fitzroy Melbourne Australia

I am trying to locate POTTER family members that come from Fitzroy, Melbourne, Australia
Parents are Violet Eileen POTTER (nee Darcy)& Kenneth John POTTER from Bendigo, Victoria then later moved to Fitzroy they had 3 boys and one girl
I believe the girl - Violet Faye Potter is still alive and has married and could be living in Coburg, Victoria
Any information would be greatly appreciated and would it would be wonderful to have contact
I am the grand daughter of James Elliott Potter
