Sarah died (believed in child birth) in Dec 1854 - could not find a death entry
I strongly suspect that's because she probably didn't die in 1854!
She is on the 1841 census as aged 3, with her father
Thomas Blakey, butcher, mother Elizabeth and siblings in North Shields. Also in the household is someone with the surname
Kell. (HO 107 / 825 / 10 / 39 / 25)
In 1851 census aged 13. In 1851 she is living with her mother and step-father John
Lough in North Shields (HO 107 / 2409 / 442/ 11)
In 1857 there is the birth of a Mary Ann
Kell Mason, birth registered 3rd q. 1858, Tynemouth 10b, 113. Mother's maiden name
Blakey.
In 1861 there is a married Sarah Mason, 23, born North Shields, working as a house servant in North Shields in 1861 ( RG 11/ 3837/ 83/ 62)
Also in 1861 a Mary Ann
Kell, aged 3 is living with a Mary Ann
Lough and her son Ebenezer
Blakey in North Shields (RG 9/ 3837/ 60/14)
Finally the death of Mary Ann
Lough Mason aged 9 in Tynemouth in 1867.
I appreciate this isn't finding your Joseph's parents, but a bit of unravelling of the story is needed, I think
