Hi - just managed to dig out some more information! I think it was 1940 onwards (not sure until when). Roy had a younger brother, Brian, and I think their father's name was Leslie, his mother was possibly Lilian?? Apparently the Croft family might have been lived on Avondale Rise in Peckham, with my father being on parallel Danby Street before they both moved to other addresses. Leslie and later Roy worked for the London Press Exchange [an advertising agency] and were both Account Executives.
