Hello Genielewis,
Thank you for that, seems he was not a very nice man at all. As he married Louisa so soon after his wife's death and her husband had died in 1929 maybe they were already together by then

and just made it legal. Will check the Electoral Registers next time at Library and see what turns up.
Hope you don't already have this info but will post it anyway.
Frederick was killed by a train Thursday June 14 1940 at Oxley, Brisbane, He was deaf and didn't hear it coming apparantly.
There is a Newspaper report-Bathurst Daily Argus 11 May 1909 headed "The Peculiar Whitwell... Breaks Things With a Pistol". so it appears he was bad tempered before his injury in WW1.
There is also a report of that court case in the Sydney Morning Herald 12 may 1909 entitled "A Variety of Charges", but the quality is not good enough to post here.
If you go to.....
http://trove.nla.gov.au/newspaper and type in his full name the articles will come up. (Hope the link works) there are a few other arrticles there as well.
