I am not kidding - they are called 'loose papers.' LDS did not photocopy them.
Also remember the estate settlement may have been 30 years or longer in appearing. Why? Everyone one knew who the heirs were, so they stayed on the land. It was only later when the land sold 'out of the family' or was further divided up that the records appear.
I am a New England researcher. The south has these 'loose papers.'
