Cattaraugus County Information Cattaraugus County, NY was created in 1808 from southwestern Genesee County. However, Cattaraugus was not finally organized with its own county government until 1812. For that reason its residents were numbered along with those of Genesee County in the 1810 Census. The township of Napoli was organized in 1828 but it is not included in the census indices until 1840. Its residents in 1830 were apparently enumerated along with those of Little Valley.
