I have found an Elizabeth Jean Isabel Howard, spouse: William Dennis Robinson, unfortunately the children were not listed on the document. Elizabeth's Mother was documented as being Jessie M. Howard, and her father Albert Howard. She was born 1910 in Bathhurst, New South Wales, Austrailia, and died the 9th of June, 1986, and died in Oberon, New south Wales, austraila.at the age of 75 years. The source for her birth was:
Australia Birth Index, 1788-1922 Original data: Compiled from publicly available sources.
Her first spouse was listed as" Private" Her second husband as being William D. Robinson. They married in 1934 in Mudgee, New south Wales. Source:

I regret that I could not find "Billy" or "Bill", but this might be a place to start.
