Hi Albert, My great grandfather was in the 1st light horse brigade. I sent away for his service records,and I was amazed at just how much information I received from them.Perhaps it might be well worth sending away for your Uncle's records? Kind regards, Sharron Grilk P.S I'm in the middle of family tree research ,and I have been told that the "Grilk's" changed their name to "Grulke" at some stage.Do you have any info that would assist me?
