After reading that Copyright can foil your effort I did some looking into this matter.
From what I was told; Copyright is a matter for each cemetery, if you must just ask the local council.

If you just happen to live near or be going to Pilton, Somerset in the UK, and your looking to fill in some time, you could always tour St John the Baptist church and/or the graveyard there.

Not only would the headstones tell some great stories, but you might come across the headstones of my
MASTERS family there. If you do, could I ask you to take some photo's for me, and send them by email to me in Australia please. Circumstances dictate that I will never make it there, as much as I would like to.
If anyone can oblige me with my request I would be greatly appreciative. Thank you for reading my post.
