History

Hillsborough was one of the five original counties identified for New Hampshire in 1769, and was named for Wills Hill, 1st Earl of Hillsborough, who was British Secretary of State for the Colonies at the time. The county was formally organized at Amherst on March 19, 1771.

In 1823, twelve townships of Hillsborough Country – Andover, Boscawen, Bradford, Dunbarton, Fishersfield (now Newbury), Henniker, Hooksett, Hopkinton, New London, Salisbury, Sutton, and Warner – became part of Merrimack County. The town of Merrimack along the Merrimack River in south-central Hillsborough County was not included in the newly formed county 9 miles (14 km) to the north. Hillsborough County’s administrative functions were moved from Amherst to Milford in 1866, and then to the current seats of Manchester and Nashua in 1869.
