Hi Nikki - Porteils info in Australia always seems hard to come by! John Ernest married Mabel Daphne Mould and had 1 child, Archibald John, b1921. It seems John Ernest, William and Lawrence enlisted 1915/1916 and details are shown on National Archives war records. John & Mabel (my father's cousin) separated when Archibald was infant and were always part of our close family. Arch was like older brother to us and he died in 2003. I now live in Brisbane and my email is patsumner@bigpond.com I am happy to pass on any info I have. Regards Pat
