Good afternoon Gail, You are in the same place I am, I'm searching Gibbs of this Cape area, where I live. You want to check Wareham, MA. Historical they even have tours in Summer. Now my scrapes of paper I have found in attics and books tell this story. Rev Rowland Thatcher first preacher of Wareham, had a daughter Desire who married David Nye, and a daughter Martha who married John Howland ( he was of Barnstable ) the daughter I'm searching married John Gibbs. If you would like more info contact me. Edie Young/MA.
