Each lot history give the original lot number, original owner, the current address, the owner of the lot in 1860, a description of the lot or dwelling in 1860, a recital of ownership with as much detail as is known, a comprehensive lot history, any known residents in 1860 (may be different than lot owner), and any family notes on any residents mentioned in the lot history. The research is comprehensive, but not necessarily exhaustive. Thorough information for all lots was not always available to the researcher.
