content: These were identified as from the vicinity of Chain Bridge, which is a bridge over the Potomac River between the northern part of Arlington, Virginia and the Northwest of the District of Columbia, a few miles upstream from Georgetown. These were presumably found during the era of the 7th version of this bridge, which was built in 1874 and lasted till 1938. (There have been bridges there since 1797, but the first true "chain bridge", a chain suspension bridge, was the third bridge at the site, built in1820.) See Fearson, Jim ."Chain Bridge: A History of the Bridge and Its Surrounding Territory 1608 - 1991."
