Tips
  • If at first you don't find a name, try again under another spelling.
  • Photocopy each ancestor's census. Identify where you found it.
  • Look for an ancestor in every census during her or his lifetime.
  • On the family group record show each person's census listings.
  • Study others in the same household, neighbors, and anyone with the similar names nearby on the census in community context.

1810-1855 Index Territorial, state, and federal censuses have been indexed in one alphabetical sequence along with county election returns and other records. Records for the 1825, 1835, and 1845 state censuses of many counties are missing or incomplete. The Illinois State Archives has the original card index complete through 1855. A microfilm copy made before the index was completed is:

  • Name Index to Early Illinois Records (Springfield, Ill.: Illinois State Archives, 1975). On 248 [FHL Films 1001592+]. At the time the index was microfilmed, most of the indexing of the 1855 census had not been completed.

Why use a census?

A well-indexed census is one of the easiest ways to locate where an ancestor's family lived and when they lived there. You can also use censuses to follow the changes in a family over time, and identify neighbors. These and other clues provided by censuses are important because they help find additional kinds of records about the family.
