Hi Catherine, Just wondering if you found at where your stepgrandfather is buried. I came across the burial when doing some family history on the Ashfield council website of cemeteries for Hucknall and looked up the incident on the web, I used to work at Rolls Royce hucknall myself , but later on 1964. My mum worked there also and was a waitress to the test pilots and served their meals and laid out tables for them. Unfortunately she is no longer alive and I don't know if she would have known Keith.This should take you to the page the burial is entered on.

Apologies if you already know this. Best Regards, Di.
