How to Use the Records
Begin your search by finding your ancestors in the census index. To search the index you will need to know:


 * The name of your ancestor. If your ancestor was unmarried at the time of the census you will need to know his or her parent's names.
 * Where your ancestor or their parents lived.

Search the Index
Search the index for entries that may match your ancestor. Compare the information to what you already know about your ancestors to determine if this is the correct family or person. 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.

Using the Information
Use the locator information in the index (such as page number or family number) to locate your ancestors in the census. When you have located your ancestor in the census, carefully evaluate each piece of information about them. These pieces of information may give you new biographical details that can lead you to other records about your ancestors.

For example:


 * Use the age listed to determine an approximate birth date.
 * Use the ages and place of residence to locate the family in federal census records.
 * Use the race information to find records related to that ethnicity such as records of the Freedman’s Bureau.

Tips to Keep in Mind

 * If your ancestor was in the militia they may have military files in the State or National Archives.
 * It is often helpful to extract the information on all families with the same surname in the same general area. If the surname is uncommon, it is likely that those living in the same area were related.
 * Be sure to extract all families before you look at other records. The relationships given will help you to organize family groups. The family groupings will help you identify related families when you discover additional information in other records.
 * Married family members may have lived nearby but in a separate household so you may want to search an entire town, neighboring towns, or even a county.
 * You may be able to identify an earlier generation if elderly parents were living with or close by a married child.
 * You may be able to identify a younger generation if a young married couple still lived with one of their sets of parents.
 * Additional searches may be needed to locate all members of a particular family in the census.
 * You should also be aware that the census may identify persons for whom other records do not exist.

If you do not find your ancestors in the census try the following:


 * Look for alternate spellings of the names.
 * Look in neighboring counties or states.
 * Look for another index. Check with local or historical or genealogical societies as they often have indexes to local records.

Record History
The state constitution of 1848 accepted the federal decennial censuses as the basis for apportionment of representatives, but also provided for state censuses at mid-decades. As a result state censuses were conducted in 1855 and 1865. The state constitution of 1870 ended the practice of state censuses. Census returns for 1865 exist for 99 of the 102 counties.

Why the Record Was Created
The census was compiled to obtain a count of the population to determine how many representatives the state would send to Congress.

Record Reliability
Reliability of the information in the census is determined by the accuracy of the knowledge of the informant, which could have been any member of the family or even a neighbor. '
