I'm not 100% sure I've got the right person but... When they're buried, is their death recorded in detail or with just a surname? Or what? And, if they were Catholic, would they still be buried in a Catholic cemetery?
I work in a prison. The history of our one I should imagine would be the same for others in the U.K. When hanging was much more prevalent and a regular occurrence (1700/1800s etc )the family had to pay money to have the body released. Unfortunately if the family was unable or unwilling to do so most were put in a lime pit, so not even an official burial and definitely no headstones.
