There is only one Stanley and that is Yardley Cemetery but there are quite a number of burials for William - one at Yardley. If you contact the cemetery they should be able to tell you if they are the ones you are looking for.
You can try this site but I am not sure what info you will find. Many graves do not have gravestones.Would you know of anyway to find the gravestone inscriptions of Callow burials in Keystone/Warstone cemeteries
please.
I have found this https://www.findagrave.com/memorial/213179467/elizabeth-callow#view-photo=209085003
Thought that might be the case about the money and being able to afford a gravestone but just thought in that case it would be an unmarked grave. But how did this work? If they all died at different dates how would their names be put on one gravestone.
