I don't know how Lt GRAY can be found now, nor even which service he belonged to. There are too few with the three of his names and too many just William GRAY.
I sent to the UK National Archives to see how much it would cost to have a copy of the record for the Tank Corps man - 73 pounds

was the answer which I thought was a bit much.

The RN also had shipping in the area around Felixstowe and who knows where he was actually stationed. as he was using the Hotel address.
It is really amazing how much we found. Judith
