Hillsborough County, New Hampshire in the 1730s
Known then as the Merrimack and Souhegan frontier.
This was disputed border country: river farms, fresh town grants, scattered English and Irish settlers, and older Pennacook ground.

Looking around
You stand in a broad county-sized country that does not yet have a county name: Hillsborough County will not exist until later, and the 1730s map is made of grants, rivers, and claims. To the east runs the Merrimack River1, with Naticook land near the Souhegan and islands at Reeds Ferry. Inland, the path of settlement thins toward Number Seven on the Contoocook3, where lots are marked by stakes, stones, hemlock, and beech. Some places are already farms; others are only paper townships. Near the river are freeholders choosing town officers2, and farther west are house lots, a meeting-house site, a sawmill, a dam, a house, and a barn3. The land is being measured, sold, mortgaged, and argued over, while older Pennacook names and rights remain under the new English deeds.
Work
Farms, timber, millwork
The most visible work is land-making: measured house lots and common rights3 are being turned into farms. In the interior, a sawmill and dam on the Contoocook River3 show timber being cut into usable boards.
Who lived here
English, Irish, Pennacook
The place is not empty: Naticook is Penacook ground1 before it is a Massachusetts township. Among new settlers, most families came from Massachusetts and were of English origin2, with some Irish permanent settlers.
Law & power
Boundary and proprietors
Power is unsettled because Massachusetts and New Hampshire both claim the ground4,5. Locally, power comes through town meetings, elected officers, proprietors, land grants, and charters2,3.
Faith
Meeting house as center
In Number Seven, deeds already locate property by the meeting house3, even in a raw township. As across New England settlements, the meeting house normally joined worship and civic business.
Money
Land is the price
The clearest prices are land prices: one thousand acres sold for £500 and then £5503 in 1739. Smaller parcels could be dear too, with fifty-acre house lots and common rights selling for £1003.
What people feared
Frontier uncertainty
The danger most documented here is political and military uncertainty: the area is inside a boundary dispute4,5 until the Crown's 1740 decision. Later petitions from nearby frontier settlements show how quickly war fears could empty outlying townships, but that belongs mainly to the 1740s.
Home & table
Scattered first houses
A household might stand on a fifty- to seventy-acre house lot3 with rights in common land. But no street-by-street description of ordinary houses from the 1730s has been found online here.
Roads & news
Rivers, roads, petitions
News moves through official acts as much as newspapers: freeholders are summoned to choose town officers2, and settlers petition legislatures and governors. Inland people would hear news by travelers, meetings, petitions, letters, and roads toward older Massachusetts towns.
