Primary House Felling Dates: Winter 1843/4, Winter 1842/3

Secondary Phase Felling Dates: Winter 1869/70

Site Master 1736-1869 (white oak) HBPAx1 (t = 9.77 MARYLAND; 9.72 BPAx1; 8.45 CONCORD1).

Hummelbaugh House began as a small one-and-a-half story log house that was later raised to a full two stories. A dendrochronological study of the house was undertaken in the summer of 2021 to attempt to date both of these phases of construction.

Dendrochronological analysis has shown that the primary building was constructed from timbers felled in the winter of 1842/3 and the winter of 1843/4 and the secondary phase was added using timbers felled in the winter of 1869/70.
