Are there any pre-1900 tombstones you have not transcribed, photographed, etc.? Look through your records, your database, etc.
Put getting the transcription from the stone on your priority list. Old stones do not last forever and the information may literally fade away before you get to it.
And be careful relying totally on published transcriptions. Sometimes in an attempt to be helpful, people added information to the "transcription" that really was not on the stone.
But those stones may not be as legible in five years as they are today.
