Well, it seemed easier to look at the census for 1851 than the death of a John Taylor....

HO107 2242 583 18
Rochdale Road, Middleton, Lancashire
Sarah TAYLOR Head
Widow 39 Innkeeper, b Gt Leaven, Lancs
Elizabeth Dau 20 House Servant b Hopwood Lancs
James Son 18 Warper of Silk
Fanny Dau 16 Winder of Silk
Alice Dau 13 Scholar
Sarah Dau 12 Scholar
Mary Dau 7 Scholar
Selina Dau 4mths
All the children born Hopwood
So Sarah calls herself a widow in this census.
Kind regards
