It was moved intact in 1967 to its present site.","why_significant":"The cabin is nominated for its unusual full dovetail notching, done with saw and chisel, which specialists believe is unique among log buildings in the United States. It is also associated with Betsey Mo-John, described as the last Ottawa Indian living in Ottawa County, who lived there with her husband, the builder.","narrative":"Built around 1853 by Pennsylvania pioneer Henry Luckert, this small log cabin near Port Clinton, Ohio, is notable for how its logs were joined. Instead of the usual hewn notches, the corners use detailed dovetailing, a technique normally seen in furniture making, cut with saw and chisel. Floor joists, rafters and attic joists are notched the same way, and the joists do not show on the exterior. Specialists consulted believe it is the only log building constructed this way in the United States. The cabin was also the home of Betsey Mo-John, daughter of a chief and the last Ottawa Indian in Ottawa County, after her people left for Upper Sandusky in 1831. She married Luckert and later moved to Sandusky, where she died in 1908. Fruit pickers later used the cabin as temporary housing. It was donated to the county historical society in 1963 and moved three miles in 1967, intact, for restoration as a museum.","period_of_significance":"ca. 1853","architect_builder":"Henry Luckert","architectural_style":"Vernacular log construction","criteria":[],"status_note":"Being restored by the local historical society for use as a museum; the roof, foundation, door and window frames are new.
