Is there a better way to verify to ensure accuracy?
Yes. You can look at the census records for the John Chambers who died in Morpeth in 1895
AND
You can obtain the death certificate (details directly below) for the John Chambers who died in the Pipewell Gate area in May 1894.
CHAMBERS, JOHN Age 40
GRO Reference: 1894 J Quarter in GATESHEAD Volume 10A Page 449 You will see that John Chambers who died in Morpeth was from Scotland, born abt 1847-48.
His family seem to have come from Peebleshire and were in Northumberland from the 1860s working in the brick making industry.
Johns brother, William (born abt 1844 Scotland) is living in Backworth with his wife Hannah and family. This John Chambers appears to have married an Elizabeth, but it looks like she died before they had any children. I doubt this is the John you are looking for, and I cannot see any sign of him being in Gateshead.
You can check this yourself. Yesterday I sent you a PM with information about how to access census records on FamilySearch, and how to obtain birth and death certificates from the GRO.
