Yes, the NYState and Federal census were two entirely different enumerations. You might check the web site of the NYState Library at Albany for a discussion of these records (http://www.nysl.nysed.gov/gengen.htm or the Archives: http://www.sara.nysed.gov/) I'm unsure of the months of each (I personally haven't researched the NYS census any earlier than the 1800s). Not all counties are extant. I do have a printed list from the NYS Library giving the counties available in each census year. Best of luck, Barbara
