Hi Ann,
try writing ( e-mail) to the Bristol
library. Give them the exact date of the the inquest etc( which should be on the death cert), and the name, cause of death, plus the name of the coroner etc, basically all of the details you have on the death cert.
My gg grandfather had an inquest into his death, the Bristol Librarian found the newspaper report of the coroners inquest for me, and sent it out to me here in Australia by post .She really was most helpful.
Bristol Library really is a joy compared to some places- very quick response to emails, queries, and very, very helpful.
Kind regards
