Tyhne
Pte J McKissock wrote to the Editor of the Standard from France on 9 April 1917 saying that the newspaper was enjoyed by all the Port Melbourne boys at the front. He enclosed the issue of 6 January 1917 signed by the soldiers from Port who had read it. Pte Tyhne was one of those men.
It could be that the name was misspelled in the newspaper article and could have been Thyne. In which case it could have been one of three brothers who lived at 4 Little Princes Street – Henry Thyne, James Thyne or John Andrew Luke Thyne,
