Thank you for writing, and for the information. A lot could have happened in the editing process. What always made me doubt her was that she never wrote anything else.
And, yes, I knew that she and Capote were not related. It was another FRpr who wrote that.
Lee's explanation is:
"Two reasons: one, I wouldn't go through the pressure and publicity I went through with To Kill A Mockingbird for any amount of money. Second, I have said what I wanted to say and I will not say it again."
BTW, Lee published a few short stories after To Kill A Mockingbird.
