In looking at the transcribed records of Bream, I notice all of the 1929 burial entries have in the notes section "Entry in Left Margin" followed by a number such as 6179/3. I do not know what the number represents but I would imagine it would be something like a grid number of the location of the grave or similar.

Gloucestershire Archives hold the original Parish Registers for Bream but as we always do a full transcript of what is written in the Registers you would not find any further information than what you see on the transcribed record on this website.
