Some transcribers are confused by footstones, which often have only the deceased s initials, or perhaps a first name, and think the footstone represents a distinct burial. I have never done stone rubbings. I have read articles that say rubbings can damage monuments. I offer no insight on this issue because it does not strike me as something I wish to spend my limited research time doing. I regret not having taken more photos of ancestor s tombstones.
Stones break, become unreadable, or are stolen.
Always pack an extra set of camera batteries and you should probably simply install new batteries before starting on a long trip. If you are using film, pack extra film and make sure there is film in the camera before you get there. After each shot, note the number of the frame and what the subject was. Go to the restroom beforehand. Figure out where food is available or bring it with you.
