I have been in contact with David Christopher. he told me the work he did in Family Search is not correct. John Pierce is NOT Samuel and Tabitha Brewsters son! I also spoke with a relative of mine in NB, she has found John Pierce's family and spoke with them. They told her John came to NB from Ireland! The family doesnt know much more than that about him.
I so wanted to prove I am a descendant of the Elder William Brewster, but it is not so.
