A little bit of deduction from this record:-
As they were both born in York and still lived in York only searched for marriages with in York.
The earliest date for the marriage possible was 1856 Mary would have been 16 the most likly latest date was the birth of their first child (1872).
A search on FreeBMD gave two possible marriages one for John Topham and Matilda Sotheran
The other most likely between John Topham and Mary Bland you would have to get the Marriage Cert to confirm this.

The two marriages could be for the same John Topham so it might be worth looking for a death of Matilda Topham between 1869 and 1871.
Best of luck with the search.
