go to a cemetery and photograph all the stones then send the photos to the coordinator for that county at <
http://www.usgenweb.org> They have a tombstone project that will be more than delighted to receive them. I take one of those dummy plastic credit cards to scrape the moss off the names and dates, then make sure the photo is taken so the name and datew will be readable on the photo. If there is a tall stone, I take a long shot then the next photo is a close up of the names on it. This will freeze those stones in time. I've photographed several whole cemeteries in my county for my website.
One more thing, a couple of sets of rechargeable batteries and you can almost get a whole small cemetery in one take. I've sometimes had to go back numerous times to get the whole cemetery, but it's worth it.
