Elz,
Looking at the info you have, it seems as if most of it is based on family "oral history" ?
I can see the death registration of Eleanor, in March qtr, 1962. aged 59.
But as yet I cannot see other records that should show up to match your other info !
Although Seaham had many Irish ( including workers from County Sligo encouraged to work in Lord Londonderry's coal mines) Whitehaven had a larger Irish element. Like a smaller version of Liverpool, many Irish entered England in 1800s etc, via Whitehaven.
Is it possible that Eleanor was born in Ireland, not England ?
The name "Eleanor" is a variation of the name "Helen", but many Irish preferred the "Ellen" variation ?
You quote " George Johnston c. 1969 " Is that his death year ?
