Many thanks for your kind response Kevin. Unfortunately, I am unable to resize the picture but could email it to you? I know that he called himself John but on the back of the picture (which isnt easy to read) it says Jan/Jon Johana/Jahana. I know this isnt very helpful but the people that would know have since passed away. I was told that he was killed in the war but I am not sure if that was true as my Grandmother wasnt married to him.
