Thanks for all the data!! I am also posting here to share the clues.
Correct me if I am wrong!! But I think we found the line.
Eliza Fernald and Joe Fleming Bryant Newcomb Fernald and Abigail Pratt Lemuel Fernald and Mary Wiggins Evans Thomas Fernald and Anna Kenniston Abraham Fernald and Mary Trickey Thomas Fernald and Mary Thompson John Fernald and Mary Norman Spinney Renald Fernald Joanna Warburton
Since you have documentation that Lemuel Fernald/Furnald is Bryant's father and it is known they are from Nottingham NH. And you also have documention that a Thomas Fernald is Bryants grandfather. Then my guess is that Thomas is most likely the son (or possibly the grandson) of Abraham and Mary Trickey of Nottingham (formerly of Kittery, ME). It is said on Internet records that Thomas and Anna had 14 children. But I have not seen them all listed. I only have Thomas Jr in my database. In any case Nottingham is the place to research.
When I sift thru the data you sent and do some more digging, I'll contact Jonni Sue to verify and confirm these leads, (from Abraham, I believe these people are closer to her line) then she can add them to the database.
