Rockingham County location map. Where is Rockingham County?
History
The area that today is Rockingham County was first settled by Europeans moving north from the Plymouth Colony in Massachusetts as early as 1623. The government was linked tightly with Massachusetts until New Hampshire became a separate colony in 1679, but counties were not introduced until 1769.
Rockingham was identified in 1769 as one of five original counties for the colony. It is named for Charles Watson-Wentworth, 2nd Marquess of Rockingham, who had been Prime Minister from 1765 to 1766. The county was organized in 1771, with its county seat at Exeter. In 1823, a portion of Hillsborough Country became part of the formation of Merrimack County. In 1844, its area was further reduced by the formation of Belknap County to the northwest. In 1997, the county court facilities were moved to Brentwood, a rural town adjacent to Exeter.
