This voluminous work treating 18,000 individuals in all consists of genealogical notes on specific New York and New England families, as well as a miscellaneous section of source records pertaining to families of the region. The genealogical notes provide exact dates of births, marriages, and deaths of all members of a given family, working back to the original immigrants to this country and forward to the last quarter of the 19th century. The section of miscellaneous notes includes Bible records (with cross references to the above genealogies), records of burials in New York from 1727 to 1757, and an index of intermarriages for both New York and New England families. A dense 50-page index contains the names of all persons referred to in the genealogies.
