This is an extensive collection of genealogies of the first settlers of Schenectady, tracing families in the direct male line for at least three generations. The compiler based his research, in large part, on the baptism and marriage registers of the First Reformed Church of Schenectady but otherwise drew on records of the Secretary of State of New York, the Clerks of the City and County of Albany, and the Court of Appeals. The result is a genealogical compendium of unimpeachable authority.
