Hi,
This is very interesting. Before John Blenkinsopp died, there was a record for Robert Henry Blenkinsopp (another son) at the Bishopwearmouth Boys C of E school, from 1897 (parent given as "John".) Then, in1899 John died, Eleanor moved to Blyth with the children and remarried to Frederick Watson. In 1902, a daughter Eleanor was born; and all of the family was living in Percy Street in Blyth.
Then in 1905, the family was in Bishopwearmouth, where Eleanor, the daughter died. In 1908, they were still living in Bishopwearmouth (15 Hopper Street), and then went back to Blyth. From Blyth they then went back to Bishopwearmouth; this time to Back Elgin Street.
But, on the 1911 census, James is living with the rest of the family at Gladstone Street. Lots of moving back and forth! Strangely, on the 1911 census, Frederick Watson is not with them and Eleanor has recorded her marriage as 32 years?! (It would have been 32 is John Blenkinsopp were still alive.) From 1911 until hear death in 1938, Eleanor lived at Percy Street in Blyth. It's very confusing.
