Hi garthj,
I see from John Turbitt's war record it is very precise, right down to being able to envisage what he would have looked like, from his personal description. But alas, tantalising short on who was his next-of-kin, which is what you want to know.
However, "km1971" who came on to this thread, is a wiz on military matters. He has given me tremendous assistance so hope that he spots your request and can be of help.
Good luck, Bonnie
