The first census for the Commonwealth was in 1785, while the first Federal census was taken in 1790.

Until the latter part of the 17th century, members of the governor's council were exempt from taxation.

The 1890 census was destroyed in a fire in Washington D.C. in 1921.

Mortality Schedules 1850 ~ 1880

Federal Censuses from 1850 - 1880 included schedules enumerating individuals who died the previous year.
