 * There may be more than one person in the records with the same name.
 * You may not be sure of your own ancestor’s name.
 * Your ancestor may have used different names, or variations of their name, throughout their life.

Using the Information
When you have located your ancestor’s record, carefully evaluate each piece of information given. Save a copy of the image or transcribe the information. These pieces of information may give you new biographical details. Add this new information to your records of each family. You should also look for leads to other records about your ancestors. For example:


 * Use the age categories to determine an approximate birth date range.
 * Use the residence to locate other records such as land, probate, tax, and church records.

Tips to Keep in Mind

 * Continue to search the index and records to identify other relatives.
 * When looking for a person who had a common name, look at all the entries for the name before deciding which is correct.
 * You may need to compare the information of more than one family or person to make this determination.
 * Be aware that, as with any index, transcription errors may occur.

Unable to Find Your Ancestor?

 * Look for variant spellings of the names. You should also look for alias names, nicknames and abbreviated names.
 * Search the indexes and records of nearby localities.
 * Try alternative search methods such as only filling in the surname search box (or the given name search box) on the landing page leaving the other box empty and then click on search. This should return a list of everyone with that particular name. You could then browse the list for individuals that may be your ancestor.
 * There is also the possibility that a family was missed in the census.

General Information About These Records
Federal census takers were asked to record information about every person who was in each household on the census day, which was the first Monday in August for 1820. A census taker might have visited a house on a later date, but the information he collected was supposed to be about the people who were in the house on the census day. The basic census enumeration unit was the county. Each county was divided into enumeration districts, one for each enumerator. The completed forms were sent to the Commerce Department’s Census Office in Washington, D.C.

Federal censuses are usually reliable, depending on the knowledge of the informant and the care of the census enumerator. Information may have been given to a census taker by any member of the family or by a neighbor. Some information may have been incorrect or deliberately falsified.

Population schedules consisted of large sheets with rows and columns. The schedules were arranged by place, such as township or post office. The places were not filed in any particular order. The arrangement of families on a schedule is normally in the order in which the enumerator visited the households. The original schedules are well preserved at the National Archives in Washington, D.C. They were microfilmed in the 1950s and 1960s. The schedules for some counties in varying censuses are missing.
