I missed the original query, so I don't know if this is relevant or has
been mentioned, but John Milner Associates excavated the Federal Triangle
site in Washington, DC about 1990?  I don't have the report, but much of
the material dated to the late 19th century when the neighborhood was
working class and consised of a mixture of ethnic groups, Irish, black,
etc.  During the Civil War the immediate area was facetiously referred to as
Hooker's Division--after the Union Major General--because the populace
consisted largely of camp followers taking advantage of wartime prosperity.
As a result, a lot of the material recovered from the site was
originally discarded from the brothels there (and, some say, one
colloquial term for prostitutes was coined).
 
The Pennsylvania Avenue Development Corporation put out a video about
the excavation.
