Thank you so much for that - I was interested to see what it said, and death from TB at the age of 36 was not unexpected. He had got through the war in the RN, had a wife and child back in the UK, so all very sad.
I am seeing he was 'late of Banka' which Wiki is saying is in India, how does this link to where his death was in Carolus Hospital Batavia (Jakarta?) My knowledge of all that part of the world in the 1920s is minimal. Or is there another Banka, I am guessing it was where he was working.
Looking on Google, there is a Bankga Island by the Java Sea. I wonder if this was where he was working at the time???
