I have established that Elizabeth Jackson née Ellerington died aged 23 at Bulmer St., Newcastle on 15th Dec. 1865. She was the first wife of William Jackson. JenB suggested the following lookup to see if she was buried at St Andrews Cemetery.

"Bulmer Street was in the Parish of St Andrew, Newcastle upon Tyne.
It's possible, therefore, that the burial was at St Andrews Cemetery which opened in 1857.
The burial books are on microfilm at Tyne & Wear Archives - some Rootschatters visit there from time to time."

I really appreciate any help.
Thanks
