My cobbled together alternative is here! Corrections made.
Is this a late marriage for Ann, or just a coincidence of names? I haven't thoroughly checked.
Sep 1872 Sunderland 10a 760
Gordon, Ann
Jones, James
Sunderland indexes ref C026BK15/373
Leaving that aside, in Sunderland in the 1871 census (free resources only for me at the moment!)

Thomas Jones 7 Durham Sunderland

Ann Sells 36 Sailors Wife Durham Pensher
Thomas G Sells 17 Sailor Durham Sunderland
https://www.familysearch.org/ark:/61903/1:1:Q271-JHGTCould the G be for Gordon??
There is a baptism of Hannah Gordon in Penshaw, Durham, in 1845
Parents Henry and Mary Ann
I think abode will be Shiney Row.
A daughter Ann to those parents in Penshaw as well, maybe in about 1843.
