Coroner's Records for the early period do not exist only a Register with
a list of death's reported, when and where, inquests held and where and
verdict. This dates from 1886 and is held at Haverfordwest Record
Office Ref T/CR-1. You may view the first book but the early part of
the second book is covered by the 75 year rule. It is possible to ask
the archivist to look for you and to let you have details of any
inquests up to 1936.
The Pembrokeshire Record Office catalogue is available on
However as this all too late for you it might be worth looking to see if
there is any report in local newspapers - Pembrokeshire Herald
(available from 1844)and Tenby & Pembroke Dock Observer (from 1853)
The former covered Haverfordwest but at that early date there is little
local news although you may be lucky.
