In 1986 a survey of the Overchurch site was carried out and a plan was produced giving the locations of all the remaining visible grave markers that could be found.
Each of the markers was numbered, and any legible inscription was recorded. One, no 13 on the plan, is believed to be medieval.
While it is difficult to see, the stone has a simple cross carved in it
A second medieval stone was found in the wall surrounding the undertaker's office at the site of the Greenbank church, this is now stored in the Williamson Art Gallery. There are other fragments of grave markers in the walls at Greenbank, parts of inscriptions can still be seen on some of the stones. This is all material that was brought from the original Norman church and used in the construction of the second church.
The graveyard, as has been said earlier in this thread, is a Scheduled Ancient Monument and is in the care of Wirral Borough Council.
The site is open and therefore subject to abuse, rubish is dumped, fires are lit and the remaining grave markers are often vandalised.
Some people think that the site should be left in its present, overgrown state, as to some extent this protects it from even worse vandalism. Others feel that the site should be cleaned up and propper access provided.
As an aside, if anyone is interested in what happened to the gravestones from the Greenbank churchyard when the Undertaker's Office was built, relatives that could be traced were asked if they wanted them moving, the rest were sold and now form part of a garden wall at a house in Noctorum.
