Find the Parents and Siblings of Your Ancestor in the United States Census, 1850-1940
Census indexes can help you locate your ancestors. People were listed in national, state and territorial census records. The national census was done every ten years. Other censuses were often done five years after the national census. Most census records are available online.
Step 1. Search for your ancestor in a census record
Search in the United States Census collection at: www.FamilySearch.org (free).
- Use the ancestor's name, birth year and birth place for a successful search.
Tips for success:
- Always look at the original record, not just the index or transcript.
- Find your ancestor in each available census.
- If you don't find the person in the census nearest their birth try one near their marriage or death.
- If you only have initials for one parent's given name try searching by the other parent's given name.
