The burial would have been in a community grave often referred to as "pauper grave" if the burial was funded by the workhouse. There was no kerb or headstone but possibly a temporary wooden cross. By law parishes were not allowed to show any identifying name. The parish if it regularly sought a burial plot for paupers would re-open graves so that there were usually several bodies within a grave some buried a few years after the original burial. If the workhouse accounts still survive you would probably find an entry paying a sum of money on or about the date of death recorded with possibly the initials of the deceased.
