Hi again Debra,
Attached below is the little I know about Alfred Sydney Campbell. I have never been able to find his birth which he states to be in Prahran victoria. I have also never found his marriage and he and Elizabeth Hart appear to have separated after 1901 and well before WW1. He then appears to have worked as a shearer.
