Even if there is no other instance of this surname on the page, the census reference is useful to get a feel for how the enumerator formed his letters
If I got the right census return then the full record can also be be used to work out leads such as the following:
Marriages Q4 1884 Manchester. 8d 359 (per freebmd)
John Windridge - Mary Ann Croft
Lancs BMD shows that this marrriage took place at Manchester St Philip - their local ref is 93/5/353
and the GRO site which gives MMN prior to 1911 is free to search to check out the childrens' births to cross ref the MMN, if you search though systematically from the marriage year, you can possibly find children born and died too soon in between census years.
