Fragments from two different sites (one 17 c. one 18th c.) have been
recovered in St. Mary's City. Noel Hume found part of one at Martin's
Hundred, and several pairs are curated at Colonial Williamsburg, though I
believe they are from the Public Gaol. There was also a fairly intact set
from the excavations at Oxon Hill Manor done by John Milner and Associates
(John McCarthy and Jeanne Ward - as I recall)
