Hi
Finding a burial entry in a church register can be done in earlier 19th century registers but is hard as not knowing which district, parish, town or village hamlet. If your lucky MI's can be transcribed. By the 1900's (20th century) most parish registers were kept by the church archives with no transcription or film record (Few were)
By the 1960s the most likely will be grave records & location plot maps or cremation remembrance books but these where kept by each cemetery or crematorium administration but which!
You don't give any idea of location in West Yorkshire or if buried or cremated or even buried at sea.
Total impossible task! without more info.

Local Newspapers death entries may be the best starting point but again where! which hamlet, village, town or city
