I trust the following may be of help.
From May’s churchyard survey I have found the spot where your Elizabeth might have been buried.
May’s survey primarily concerned the older part of the churchyard, where plots/graves are identified by numbers, some of which have alpha suffixes. The plot where Elizabeth may have been buried is 224v.
In the Survey May has put the name Corns - no mark next to that number.
Unfortunately, the suffix v indicates that a person, it could have been May herself, had provided information employing local knowledge.
Having found that record I examined others with similar numbers. I found that the dates given on the inscriptions varied widely, for example 224 is the Keay family where the dates given are 1886, 1888,1898 and 1903..
223 Shirley Yates died 1949
222v Lees - no mark
221v Gittins - no mark
221vv Lees - no mark.
225 Lake - no date – Vase
226 Corns 1944 and 1945
From the above you will see that the dates given are many years apart – from the late 1800s to 1945. You will also see the large number of ’no marks. The reason for both could be because in that area, memorials have moved downhill or simply sunk into the ground due to the fact that Wombourne is built upon fine sand. Lines of plots that were once straight are now anything but straight and there are many blank spaces.
If you wish to visit the location 224v then I will gladly provide details to pin point the location.
Alternatively, I could send you a photo of plot 224 and/or 226. As I said previously I hope this is of some help.
