I contacted the Gloucester Coroners Office some while ago about the suspicious death in 1916 of an aunt. They were very helpful and supplied me with a full transcript of the inquest.

They can be contacted at:

Gloucester Office

Tel: 01452 305661
Fax 01452 307935

It is best to write, rather than ring, giving as much detail about your request as possible.
