Hello again Pennines,
Why not just phone up the church and ask where you can access the Memorial Inscriptions? By googling the first entry gave the phone number. I can only think of one book of Memorial Inscriptions published by HDFHS, and that was for a Colne Valley graveyard.
Do let us know if you receive an answer - I would be interested in the inscription for Agnes Wheatley who is buried at Mirfield St Mary.
Happy hunting
