Independent Archaeological Consulting (IAC) conducted multiple phases of archaeological survey for the proposed widening of the Interstate 93 from the Massachusetts border at Salem, New Hampshire, through Windham, Derry, Londonderry and into Manchester – a distance of about 20 miles. The 20-mile-long widening project for the most part follows the existing corridor but proposed to widen lanes, reconstruct exits, and expand the ROW, with the possibility of impacting archaeological sites.
The William Dinsmore Homestead is one of four sites in Windham, New Hampshire, that were aligned along Old County Road. The other three are the John Dinsmore Homestead, the Misses Dinsmore Homestead, and the Towns-Hunnewell Farmstead. Each of these resources share a kinship tie, harkening back to John “Daddy” Dinsmore (b 1671), who arrived from Ireland in 1723. Following a short stint in Maine, where he was captured by Indians, John Dinsmore settled on 60 acres in Windham.
