Hi Sue
Yes Sale, Vic,Aust,been doing a bit of searching and found his marriage here to Euphemia SCOTT in 1857,BUT it still needs to be checked,to be 100% sure.
And yes it could have been one of the boys.My guess is,it was Edwin giving his name and fathers name John."Edwin John".then shot through,although on his death cert only the 3 childrens names are given.
