I found myself yelling ' What about Parish records ' at the TV at that point !! lol Interesting episode , as my maternal grandfathers side came from Ireland to Liverpool , and eventually settled in Coventry,
Like RT I have 2 ancestors ( father and son ) who died due to accidents, rail though not horse/ carts , one was a driver of a train that crashed , though he was the only fatality, ( and after a lengthy inquest was found to have been at fault for the accident, his son died 35 years later in a goods yard accident
