Peter, in addition to the 1904 death for William in Sheffield there is Emma 67 died Sheffield q1 1905..
According to GRO they had several children but two died young, Joseph born and died 1857 and Rose born 1861 died 1868 age 7. Both in Wortley. Note that parts of Wortley reg district moved to Sheff reg district 1901. I cannot find burials for any of these four deaths. It is likely that all four are in the same place. That means we can say theywere not buried in any of the places for which we have records in the period 1857 to 1905. Unfortunately that covers quite a few places if you look at the dates given.
