If you choose Redhill from the dropdown list and put in grave number 2525 there are four burials.
That's a good find Dizzifish - I did notice that her mother Hilda Bateman's grave number was the same but did wonder why I couldn't find a death for Lille's husband John (Helmsley/Pratt marriage registered Dec 1936 Nottingham)
I think Hilda Cooper's mother is Ellen Maud Allsop married Tom Cooper 1881
