1865 New York State Census

As one of its many service projects, WNYGS organized the preparation of an amended index of the 1865 New York State Census for Erie County.  Many dedicated volunteers worked on this project over a number of years. While originally collected and documented on index cards, the society later created a digital version that now resides here for genealogical researchers.

It is important to note that while planning and researching this project several existing printed and online indexes for Allegany, Cattaraugus, Chautauqua, and Niagara Counties were identified; those resources appear below.  At the time of the project, no censuses were available for Genesee or Wyoming Counties.
