To River Tyne Lass, Tickettyboo, AllanUK and Chris Doran, many apologies for my delay in replying to your latest posts. Many thanks also to River Tyne Lass for your efforts- when I saw the details on the inscription I remembered it from my visit to the cemetery when in Newcastle some 10/11 years ago. I remembered that Maria ( my greatgrandmother) had died during the First World War and the inscription obviously confirmed it. I have a vague recollection from burning the midnight oil one time when doing family history research that Peter-Maria's husband ( my greatgrandfather) died after her, but I might be wrong-old age! If however I am correct the fact that his death isn't recorded on the inscription suggests that it was after 1925 when Mary died. Anyway that's another avenue for me to research!
To Tickettyboo many thanks for having one of those "lightbulb" moments and doing some great detective work to locate the actual grave.I'll now be able to give my relative the information she was trying to find.After my initial post I did follow up some of the advice given and fired off an email to Bereavement Services @ Newcastle Council but haven't had a reply yet. Now that doesn't really matter.
Many thanks again to all who replied, Pirhana.
