If you check over to the left you will find a list of cemeteries /graveyards that we have transcribed. Tinsley is not one of them.
Are you sure they are in Tinsley?
It maybe worth your while just to enter their names and see if they come up at another cemetery.
Tinsley has been covered by S&DFHS but not sure of the dates they covered.
Many of the Churchyards were transcribed by S&DFHS for the National Burial Index but most had a cut off date around 1910. The more recent ones we not indexed.
Just a few bits of info for you to keep in mind as you further your research.
