History
- the text in this section is copied from an article in Wikipedia
Hillsborough was one of the five original counties identified for New Hampshire in 1769, and was named for Wills Hill, the Viscount Hillsborough who was British Secretary of State for the Colonies at the time. The county was organized at Amherst on March 19, 1771. In 1823 a number of towns were removed to become part of Merrimack County. Over several years ending in 1869, county administrative functions were moved from Amherst first to Milford in 1866 then to the current seats of Manchester and Nashua.
