Benefits of Censuses
- Censuses reveal specifics about the family, such as names, ages, birthplaces. (See Contents of Federal Censuses)
- A census locates the family—where records about them were likely created. (See Using the Census to find other records)
- Every census of the family provides clues that help you learn even more about them.
Census Tips
- Why:
- Relatives, such as grandchildren or married children, may live with them
- They may live with a child, such as a married daughter, in their later years
- Neighbors may be relatives or old friends from their home state.
- Why:
- You may find sisters living in the area.
- Your ancestor's widowed mother may have remarried. In those censuses, were the women the right age(s) to be sisters? Aunts? The mother?
- One of the husbands and your ancestor may have witnessed one anothers' deeds or other documents, perhaps suggesting they have become relatives.
- Why:
- Gaps in ages of children may be a clue to:
- A second marriage of the couple: Check marriage records for this.
- A child died young. Check cemetery, church, funeral, and other records.
- Where the children were born (state, nation) may be a clue to:
- Ages of husband and wife may be clues:
- In a second marriage, the husband may be older than the wife.
- Compare ages of the wife and the children:
- The oldest child: was the wife too young to be the mother? (Child-bearing years for most women were between 16–40.)
- The youngest child: was the wife too old?
