New Hampshire Maps Index

The historical maps of New Hampshire are powerful tools for genealogists, capturing town boundaries, land grants, and settlement patterns. Town plats and early colonial maps from the 18th century document New Hampshire’s chartered towns and original proprietors. County atlases of the 19th century frequently include names of property owners, while Sanborn maps add detail for urban locations. Boundary disputes with neighboring states, such as Massachusetts and Vermont, make maps key for locating shifting jurisdictions. The New Hampshire State Archives and local historical societies maintain excellent map collections. These resources help illuminate ancestral homesteads, family clusters, and the economic life of rural and mill-town communities throughout the Granite State’s history.
