It can often be worthwhile talking to the warden or archivist, especially with churchyard graves.
I recently took a trip to the graveyard where my g.g. grandparents are interred, to see if I could prove any family links to others in the same area with the same surname. Grave photography proved fruitless because so many stones were unreadable - the grave yard was in SE London, next to a busy road, so I guess pollution had taken its toll. I was just about to leave in despair, when I found that the church doors were open, and people were milling around inside (a Sunday service had just finished). I asked if there was anyone available who had access to the burial records, and I was very lucky to find the church archivist actually in the church.
The archivist very kindly looked up the whereabouts of the burial place of my g.g. grandparents, and she also looked up who else was buried in the grave, and we found that their 4-year-old grand-daughter (who they never met) was also interred there. I left the archivist a list of about 6 other names of people that I was interested in, and some money to cover postage, in the hope of finding out more. I was pleasantly surprised to get a reply the same week, which listed the resting places of the other people, and found that they too had others in the same grave. By tracing these others, I am now much more sure that the other people with the same surname were indeed close relatives.
So, don't give up hope if you can't get to a graveyard to take pictures, or if you do get there and find no pictures to take, because quite often there are paper records surviving, and you have to track them down.
