[JACKEROO]

  does anyone know if there is access to electoral rolls for south australia from 1922 until 1955, 
there is no census, i am trying to locate lucy davey last known to be living in or around glen osmond in sa, i know she died in 1955 at glen osmond sa, but trying find out where she lived before that and maybe with who, due to changing my email i can only pick up replies when i log on,have to find out how to change and get past the password dilemma. appreciate help
