Solved! You probably already know this but I was curious, so looked for Mary in the census
1891 RG12/4014 Folio 37 Page 25
29 Bowley Street, Middlesbrough
William Bingham head wid 53 General Labourer Nottingham Fenton
Mary Firth sister " 67 Lincolnshire Langworth
Ernest Firth grandson 11 Scholar Yorkshire Sheffield
Mary E Preston visitor 7 " " "
It's a relief to know we had found the right grave!
Middlesbrough archives just phoned to say that there are two burials for that grave, Mary Firth in 1891 and the other 2nd September 1901 - the name wasn't legible on the microfiche, he said, but must be your William.
