Thank you, Queenie & Carole W for your replies.
I had done the census search some years ago with negative results (hence age/occupation not really relevant) and should have mentioned that--my apologies!
I was hoping that someone might have access to brewery or other commercial directories for Brighton at around the time-span given.
From browsing the QH website it appears to be a free-house, but if it was owned by a brewery in that time-frame there may be company archives for me to contact.
