Hi Ali
By this date, they would almost cetainly have been bried in one of the cemeteries, unless they were in a small village where the churchyard was still being used. In the case of Pendlebury it would be the cemetery.
Not sure which though. It might depend on family and religion as well as area.
My family from there were at Moston but they were RC. Weaste and some others have some entries indexed on;line but you pay for the original.
I'll look for the address.
Also, if you email local studies with an exact date, they might look for an announcement in the Manchestyer evening News. All my family in the area and loads they knew used it. It nearly always gives a burial place for ours.
Do you have a name you can give? People may know other databases.
Best wishes
