Thank you so much for your informative post. To begin with, I appreciate the part about how to handle postings and follow-ups. I try very hard to respond back to everyone that takes the time to help me out, but had not considered that if I post on more than one board, others might be repeating the same work that has already been done or not know if my question has been answered. I will certainly take that into consideration in the future.
Furthermore, what a gold mine that you sent me to look over. By looking at some of these websites, it certainly seems possible that my third great grandfather Jason Morrell is the Jason Morrell son of Enoch and Thankful. Unfortunately, where some of the siblings of Jason have descendants and spouses listed, Jason does not. It would be nice to have some children or my second great grandfather Walter listed, so I could know for sure.
I will look into these websites you provided me more closely now to see if I can somehow get the "proof" I need. Do you have any further suggestions beyond that?
