Hi, I had this reply from GRO which is very interesting and useful . So I will cut and paste it in its entirety . All births, deaths and marriages should be recorded with the local register office were the event occurred, this record will then be stored with us here at the GRO. If the deceased is unknown it is usually the coroner that will register the death with the local office stating whatever information about the deceased they have. However it has been known that if the coroner has insufficient information then the death would not be registered. If the deceased is unknown it will be entered on the death certificate as unknown. The coroner may then give an approx. age, the address as to where the death occurred and the cause of death. I hope this information helps --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
