Census Research

Census Records are one of the best places to start research on your family. Start with the name of your ancestor and the place where they lived. In the United States, a census of the population was taken every decade from 1790 to the present. Census records are public from 1790-1940.  From 1790-1840, only the head of households were listed by name. Please note that most of the 1890 census records were destroyed. 

One source for census records is Heritage Quest . Anyone with a Connecticut State Library Card  can access Heritage Quest  from the State Library site.
