In 1847, Abiel Abbot and Ephraim Abbot compiled a comprehensive genealogical record titled “Abbott Genealogical Register,” detailing the lineage of several Abbott families originating from early New England settlers. Initially aimed to document the descendants of George Abbot, Sr. of Andover, the scope expanded to include numerous branches such as George Abbot, Jr., Thomas Abbot of Andover, Arthur Abbot of Ipswich, Robert Abbot of Branford, Ct., and George Abbot of Norwalk, Ct., among others. This volume, published by J. Munroe and Company in Boston, Massachusetts, integrates meticulously gathered data, revealing the expansive and intertwined genealogies of the Abbott families. The authors’ painstaking research and dedication to accuracy, despite challenges in data completeness, provide a valuable resource for anyone tracing the Abbott lineage or studying early American familial structures.
