LilyJ, how did you go with your search?
This is pretty bizarre, but I was in Blaydon Cemetery just this afternoon, hunting for graves of relevant family names, and I snapped an Armstrong gravestone because I recalled an Armstrong back in my tree.
It goes:
In loving memory
Francis Armstrong of Blaydon who died August 16th 1?35 aged ?2 years
Also Hannah wife of the above who died June 16th 189? aged 74 years
If you want the photo, just let me know.
Pretty freaky that after I had visited the cemetery and got back to my hotel room, I searched +"parish church" +stella +"st cuthberts" at Google and this thread came up result number 3 and I'd actually taken this shot prior.
