There appears to be some anomaly on his medal index card. CWGC & SDGW both agree that he died 16th May 1915, but his MIC says that he entered France 24th November 1915. It also notes Presumed Dead. I assume that 1915 should read 1914.
I can't see a surviving service record for him.
He would have joined around Spring 1914.
At the time of his death, 2nd Battalion RIF were in 5th Infantry Brigade, 2nd Division. 2nd Ypres was going on at this time.
Unfortunately, the two pages on Long Long Trail that would have helped you most, are both being updated. These are the links anyway, in case they are uploaded soon:
