Henk, I also think there should be six crew members but the link only refers to 5, namely Appleton (bomb aimer), Evans (pilot), Gent (Flt Engr) (similar names to local residents), McGregor and Alexander (W/Op/ Gunner).
Of the rest on your list, I assumed the Corporals not to be aircrew.
I also felt a Sqdn Leader would merit mention, as none, therefore excluded Timmins.
Therefore I was a Navigator and a gunner short.
Green seemed a possible for the gunner, but I didn't know Roberts was a Navigator

I had assumed (!) that Roberts had died in hospital possibly from a different incident, as the rest of the crew had been buried close to their home addresses.
As McGregor is also buried there, it might be that they survived the initial crash and taken to Brookwood, but then dying from their injuries.

Now you've provided a Navigator, we may have a typical 7 man crew.
