Quite a few public double oversized plots in the cemetery where many of mine are, they were placed and sized in such a way as to make the cemetery appear less crowded. Ironic that now huge swathes of it appear empty as there are many unmarked plots though it contains around 40,000 recorded burials. There are likely many more as around 20 years worth from one parish aren't recorded in the cemetery register for some reason though the churchyard in question had long since been closed.
