Just a suggestion - I wonder if No 7 is St. Blazey. I am by no means certain - it just reminds me of it.
No 8 - or what about Levant mine near Pendeen, same area as Botallack.
No 9 - as already said, St Michael's Mount.
The others I suspect are all taken in the same place, but I've no idea where. Not even a helpful church tower in sight!
