This source should be avoided. It is full of assertions in direct contradiction to recorded facts. For example, see Person:Isaac Harrington (11) where a fictitious son is created based on misreading a birth record as a death record, his purported sister Person:Susannah Harrington (3) where a death record was reported as a birth so she could be inserted into a marriage that was really a different person, and her sister Person:Tamar Harrington (2) whose birth date was misreported because otherwise it would conflict with the manipulations done for Susannah. Zero credibility. Source:Weis, Frederick Lewis. Early Generations of the Family of Robert Harrington of Watertown, Massachusetts, 1634, and Some of His Descendants, or probably any other sources, is a better place to look.
