PM Macfire, many thanks that is truely amazing what you have dug up, Alfred Barnes is the chap!
Been rooting around myself and found out he was a Chief Petty Officer (is that Warrant Officer equiv?) who was serving on HMS Illustrious during its Bermuda cruise.
He died in a Bermudan hospital on the 21 July ’40, aged 41.
At the moment I am trying to find out if there was a link between the events of the 7th and his admission to hospital and subsequent death. This might be based on a supposition from a website that I am still trying to find, which is based on eyewitness accounts from that day.

Pagen01. Your posts about your relative dying in Bermuda is very interesting to me as I have been researching aviation in Bermuda for many years. Please let us know if you find out what caused his death. It may, as you suspect, have been as the result of injuries received when the Skuas crashed on the deck. All documents I have found say that nobody was seriously injured on the Illustrious on July 7th 1940. Keep searching.
