Seneca County New York Census Records

Seneca County New York was established in 1804, prior to that date researchers would need to access census information within the parent counties, Montgomery County for 1790 and Cayuga County for 1800. The availability of free indexes for each of the census is dependent on volunteers. The primary source for free Seneca county indexes are at FamilySearch, however, they link their search to the images to be found on Ancestry, which you must pay for. You can use the roll and page number from their index and access the records via the free census images below. In this way you are able to search and view every census record in Seneca County New York for free.

A census is an official enumeration of the population in a particular area. In addition to counting the inhabitants of an area, the census generally collects other vital information, such as names, ages, citizenship status, and ethnic background. Each census can prove to be invaluable in painting a portrait of a family at a particular place and time. For genealogists, census records have become the go-to tool when conducting research in the late 19th and early 20th centuries. In theory, census enumerate every person in every household, in ever district, in every town, in the state or country the census was taken in. In reality, they did miss people, for various reasons, and quite often misspelled names. To add further confusion, most census indices have been extracted by foreigners not familiar with the handwriting of the enumerator, or the local names. This requires the researcher to be diligent in searching for an individual, and don’t always take a “no results” in a search as the definitive word.

Unless otherwise indicated, all census records listed on this page should be accessible for free. When cost may be involved those listings will include the $$$ symbols. As a general rule we do not provide subscription listings when a free website location contains both the index and the images except for Ancestry. FamilySearch currently provides this method for the 1850, 1860, 1870, 1890, 1900 and 1940 census. As a result we limit those census to only the listings from FamilySearch and Ancestry (for users of FTM and subscribers).

State censuses were created by the state of New York and were taken about every ten years beginning in 1795. Unfortunately, Seneca county struck out from 1855-1875 and all three census years their records have been lost.
