This date established the structure to be the earliest basically intact and scientifically verified barn in all of Pennsylvania.
Scientists and scholars of various disciplines have been using recent advances in dendrochronology, or tree-ring dating studies, in the Northeast along with the development of regional master chronologies for various species of trees to promote the dating of timber framed buildings and other buildings that have timbers somewhere in their construction.
However, the home owner is becoming more and more interested in knowing the exact dates of construction of both their houses and their barns.
The oak slice from the Tredyffrin double log crib English Lake District style bank barn located near Devon in Chester County, Pennsylvania was dendro-dated to 1779.
