Hmmm, I wonder......Could this be Jane's death with her surname incorrectly spelt?Deaths Sep 1885 GREY Jane 40 Sunderland 10a 283The gives a birth year of 1845 so about right. What do you think?
There is a Jane Gray in Hedley Street that would fit in 1881 wife of EdwardRG11/5011 f125 p69
Looks like that death for Jane I found is going to be the right one.
