New York State Maps Index

The vast and diverse geography of New York State is richly captured in its historical maps, offering key insights for genealogists. Early Dutch colonial maps, post-Revolution land grants, and 19th-century county atlases document settlement and migration across the state. The Erie Canal era spurred detailed mapping of towns and transport routes, while Sanborn Fire Insurance maps reveal structures in growing cities like New York, Albany, and Buffalo. Changes in county lines—especially in western New York—make maps essential for locating records accurately. Maps of Native American lands, military bounty grants, and estate subdivisions further enrich research. The New York State Archives and local libraries offer wide digital access. These maps bring New York ancestors into clearer focus across time and space.
