Site Master 1622-1739 SHPAx1 (t =8.21 DRNX5M; 7.56 FORES; 7.55 eapenn). Site Master 1712-1807 SHPAx2 (t =8.33 HOLL2; 7.44 MARYLAND; 6.88 MCYx1).

The primary house consists of a large stone structure that has had the roof raised, to give full height rooms on the second floor.


Dendrochronological analysis has shown that the timbers used to build the original stone structure were felled in the winter of 1738/8 and the winter of 1739/40, suggesting that the primary house was constructed in the winter of 1739/40 or shortly thereafter. The timbers used in the raising of the roof where felled in the winter 1807/8
