Try http://www.congregationallibrary.org/ I don't know if they have them, but they might be able to help, and then let us know because Chester NH interests me too! Hi! I?m wondering if anyone knows if Rev. Ebenezer Flagg?s records have survived and where they might be found. Rev. Flagg was a Congregational Church Minister in Chester, Rockingham County, NH from ca. 1736 onwards.
