Oxford Dendrochronology Laboratory Report 2009

A total of twelve phases of construction from eight buildings were sampled and dated as part of a multidisciplinary research project into the survival of pre-Civil War slave cabins. The project was funded by a grant from the National Endowment for the Humanities and was managed through the Department of Historic Preservation at the University of Mary Washington and the Mount Vernon Ladies’ Association.  The tree-ring dates ranged from 1785 to 1858, although the earliest of these are reused timbers.
