I don't know if those records even exist now.
My great grandfather fell down into a lime pit and there was a Coroner's
Inquist and a death certificate signed in 1871. I asked at the Dyfed FHS
Reference Library in Carmarthen if there were any coroners records and was
told no. I was advised that it might appear in the Carmarthen Journal and I
looked at that up to a month after the date of the death certificate. I
found nothing; however, I could have missed the reference.
