Research Tips for the 1800 Census
The 1800 census records are useful for identifying localities to search for other types of records for a named individual. The 1800 census will, in most cases, help distinguish the target family from others of the same name; help to determine family size; locate possible relatives with the same name; identify immediate neighbors who may be related; identify slaveholders; and spot spelling variations of surnames. Free men “of color” are listed as heads of household by name. Slaves appear in age groupings by name of owner. By combining those age groupings with probate inventories and tax list data, it is sometimes possible to determine names and birth order of other family members.
