1790, 1800, 1810, 1820
Unfortunately, these censuses in New Jersey were not saved for posterity. Before the counties were required to submit their census schedules, one supposes that they were locally processed to produce raw statistical output, were otherwise unappreciated, and were destroyed. The only thing that has survived is the 1800 Census for Cumberland County.
So maybe I will stop looking and looking and looking for something not there, and then when I do remember, maybe I can stop refusing to believe such a thing could be true.
