A few years back, Joe Harl excavated part of a former church cemetery in St. Louis that had supposedly been "moved" many years prior, but several intact 19th century burials were documented.  I've seen it in public talks but I'm not sure about publication.  You could contact Joe for details:

Subject: urban cemeteries

Hi all,

First I want to thank the many respondants who answered my (and Diana  
Wall's) query last year about urban site reports. We are working our  
way thru the material you sent and it has been very helpful.

We have another question: does anyone know of excavations in white or  
Euro-american cemeteries? We have information from African-American  
cemeteries, and there are gravestone studies from Euro-American  
cemeteries but we cannot find examples of excavation in the latter  
(which is interesting, of course).

Thansk again for any information you have,

best,
Nan
