I noticed you are looking for the burial records of Melville church. Yes there is a listing online but not all of them are listed. I had to go through the church itself to find what I needed and there is a much "Older book" that contains the older burials that may not have stones. I was looking for a relative and it was only through this "old book" that he was thankfully found.
Just contact the church itself and see if they can help. I am trying to get them to get the lists from the old book on line.
