Sarah Taylor abt 1837 Stownpland, Suffolk, England Inmate Islington London - Single Blind age 64 
actually from Stowupland ''The higher land' or 'the rural district' near Stow(market).' which equals baptism for Sarah Ann Barnard  I found 

BUT that was not her for sure 

North London Homes for Aged Christian Blind Men and Women RG13/170 Islington - Upper Holloway Folio: 53 Page: 3

Sarah A Taylor abt 1838 Nk, Suffolk, England Boarder Fulham London - well she is Sarah A but nothing else to go on

no sign a Bailey or Roberts 

Conclusion Sarah married James Taylor - he died and she worked as a Servant and then sadly  blind and ended up in Islington 

However I am not going on Stowmarket now 

I could buy MC but funds prevent and I think this is the answer

Example of possibles Deaths Jun 1890 James 54 W. Ham 4a 77

and Deaths Jun 1908 TAYLOR Sarah 71 Islington 1b 138 - some other possibles as well but this is Islington and age is right
