In anticipation of restoring the Corneau house, archaeological investigations were conducted for the National Park Service at the Corneau Site, which is located within the Lincoln Home National Historic Site, Springfield, Illinois.  These archaeological investigations were conducted in late 1997 and again in the spring and late summer of 1998.  This work consisted of the evaluative testing of the east third of the lot in that area where the house originally was located.  The second phase of this research consisted of the evaluative testing of the carriage barn and privy locations.  The investigations documented the location of the original house, the size and location of two carriage houses and/or urban barns, a mid-nineteenth century privy, and several middens.  A wide variety of artifacts associated with the early component of this site were recovered from both the privy pit and early rear yard middens.  These artifacts give us new insights into the early site occupants and their activities at this location.  The results of these investigations were discussed in terms of the discrete functional areas associated with urban house lots in Springfield.
